How To Add Different IPs In Different VLANs
Nov 5, 2008how to add different IPs in different VLANs
My customer requests different IPs in different class C, that are belong to different VLANs in the switch. Let's say
- they have 1.1.1.10 already on their server with gateway value is 1.1.1.1
- now they want to have 1.1.2.10 too.
I have no trouble to provide them a new IP, but wonder how to setup on server now? Different range will use different gateways.
VPS Providers And VLANs
Apr 16, 2009Is there a VPS provider that will sell me a VM , and put it up somewhere, and can make me another VM in the future, on the same VLAN as the original VM ?
For example, pretend VM #1 has a NIC at 10.0.0.100
in the future, I want another VM with a nic at 10.0.0.101
I was looking at Go-Grid , but I'm not sure how their pricing works.
L3 Switch That Does VLANs?
Sep 5, 2006I need a basic L3 switch for maybe 25 mbps that will do hopefully up to 50 VLANs and which will not require me to hire someone to configure it.
As much as I like Cisco, that rules them out.
The reason I'd like a Layer 3 switch is so that I can run my backups and inter-server transfers without adding to my bandwidth bill. Also, VLANS are a critical requirement as i have a lot of customers with root on their managed servers.
So i am looking at HP [gasp] switches. How "easy" is the web-based configuration widget? [I'm an advanced unix admin but networking is a mystery to me.]
This is a starter switch and once i have a full cab of servers I'll be able to spend $7K on a pair of 3560s and hire someone to configure them for me ... but until then what can i get to meet my requirements?
Vlans In 3COM
Jul 13, 2009I orded today new switch 3COM (48 port + 2giga + 2 fiber).

I want configure switch for port 41-48 access all ports;
What solution for this cenary?
VLANs Routing Help
Feb 11, 2007I'm trying to implement VLANs on my network and can't get connectivity to host servers. Here's how the network is configured. Pardon the bad ascii diagram.
In this example my upstream is providing two subnets:
111.111.111.16/28 (I'm using an IP from this subnet to manage the 3550)
222.222.222.16/29
I am attempting subdivide the /29 into two /30's in order to place a server into it's own /30 subnet & VLAN ............
Private VLANs
Jul 24, 2007What's the benefits of these private VLANs I've seen advertised around? Anyone have a good understanding?
I've read a few things about them but have yet to fully grasp the concept.
Network Boot Across Many VLANs
Dec 4, 2006I'm not sure exactly how to phrase the question. But, I'm researching how to PXE boot a server without having a DHCP/PXE server in each vlan.
Scenario: Datacenter with dozens of servers. 1 VLAN per server. Cisco switches and routers. Each server has a serial console available for remote management (OS and BIOS are configured for serial console). If an admin wants to re-install OS, they should be able to reboot the server and tell the BIOS to initiate a PXE boot request. A central install server is available to provide the DHCP and PXE boot images.
Has anyone tried this? I have been reading about the 'ip helper-address' for Cisco to relay DHCP requests. Interested in hearing about real-world setups. Or is there a better way to accomplish remote OS installs?
Ping In Vlans Not Working?
Aug 10, 2008I have two servers both in a same vlan. Both may access Internet and be acceessed from Internet I setup db server and web server internal IP each as follows:
step 1: on web server:
vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
add following:
DEVICE=eth0:0
BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.5
NETMASK=255.255.255.248
NETWORK=192.168.1.0/24
ONBOOT=yes
TYPE=Ethernet
save and /etc/init.d/network restart
step 2: on db server:
vi /etc/sysconfig/network-scripts/ifcfg-eth0:0
add following:
DEVICE=eth0:0
BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.10
NETMASK=255.255.255.248
NETWORK=192.168.1.0/24
ONBOOT=yes
TYPE=Ethernet
save and /etc/init.d/network restart
I used ifconfig to check both status, both of them are up. both of them may ping google, but when I try to ping their each other through internal IP, nothing returns.
I used command tracert to follow, found all packages were sent to Internet rather than an internal IP.
My host tells me to do it by making NAT, I have no idea on it. Anyone may help me out on how to do with NAT?
Provider That Provides Public Ip Vlans?
Aug 8, 2008we are looking for a provider that provides public ip vlans' with dedicated server purchases,
so far,,
we have found few companies that offer this at no extra charge or minimal extra charge
1) softlayer (best choice)
2) singlehop
3) nocster/burst.net (not a good provider for business hosting / not reliable / no phone support)
does anyone know of any other dedicated server providers that offer public ip vlans for no extra charge or minimal extra charge?
Route Between Vlans In Same Subnet On BigIron
Jun 9, 2007I'm looking for a solution that I can place a firewall between 2 vlans on
a BigIron router with L3 enabled.
For this moment there is one big vlan2 with a ip-route 0.0.0.0 0.0.0.0
123.123.123.123 and a router-interface ve2 with the IP of the router, the
address I use as gateway on the machines behind it.
The WAN port has the IP address to communicate with to the GW of the
carrier-router (123.123.123.122)
Because I want to let the BigIron the routing I was thinking of 2 vlans,
one for the lan-vlan and one for the wan-vlan, but this will be a problem
because I only have one IP-block what I can use.
So the sitiuation must be as follow on the BigIron:
WAN => vlan2 => firewall => vlan3(lan)
Because of the fact that the firewall will be transparent, this should be
no problem to place it between the vlans. The actual problem is how to
manage this. In simple words, I should be able to replace the firewall
with a cross-cable and it should still work.
Cisco for an example has a SVI solution for this, but I can't find such
thing for a Foundry router.
Addressing VLANs On Extreme Summit 48
Feb 13, 2007Having a slight problem working with one of our Extreme Summit 48 (ugh) switches - I've figured out most of the basics, but I can't seem to find any way to add a secondary IP address to a VLAN! This, I would have thought, would be a pretty basic feature to have. Typing "config vlan [vlanname] ipaddress 1.2.3.4/24" works for setting the primary IP, but I can't figure out how to add any more - and doing the command again just overwrites the first one.
So... does anyone have any tricks up their sleeve, or is this something that Extreme neglected to add to this model switch?
VLANS For Internal Servers - Is It Worth It?
May 22, 2008We offer colocation & dedicated servers as well as shared & reseller hosting services.
Our colocation customers and dedicated server customers are definitely on their own VLANs for obvious reasons.
Up until now, we have been using separate VLANS and ip allocations for each of the servers in our shared & reseller server fleet. I'm starting to question this policy for many reasons:
1) We directly manage all of the servers and it is very rare that any servers are compromised to the point where they can steal an IP address.
2) We are wasting IP addresses - network, broadcast and gateway addresses are required for each vlan. Additionally, if a server needs 1 more IP address, we need to add a whole new block.
If all of the servers are under our direct management, does it make sense for us to use any vlans at all? It seems that it only serves to complicate things, waste ips and add management overhead.
Impact Changing MST Instance VLANs Range?
Sep 19, 2009I've read that all ethernet switches in a MST Region need the same Name, Revision number, and list of member vlans for each Instance. So what happens when you need to change the range of VLANs in a MSTI ? Let's say that you need to add a range of vlans to an instance that spans 20 switches? How would you do that?
View 1 Replies View RelatedInter-VLANs Router With In/out Policers, Ipv6
Oct 11, 2009Can you make a recommendation for a switch-based L3 router which can
- hold a moderate number of routes (interface routes, a few hundred statics + default)
- OSPF and BGP
- MST
- 1024 layer-3 dot1q subinterfaces (or maybe VLAN interfaces)
with
+ traffic policing in and out per subinterface/vlan
+ VRRP/HSRP/NSRP
- IPv4 & IPv6 native
- 2x GigE ports
- Not tip-over under 1gbps DDoS towards a VLAN interface.
I've been using 3560Gs, but they seem to lack the output traffic policing. I'd prefer to have subinterfaces which don't run spanning-tree, versus Vlan Interfaces to a trunk interface which runs spanning-tree. These switches sit at the L3 boundary between two L2 networks.
Cost is a big factor; but I also must carry vendor licenses & support contract, if the vendor asserts that not doing so is illegal in US.

Jun 21, 2009I have an office internal website and I opened a port in the gateway of my office (7080) to this website (server )'s 80 port. That makes this website open to public as office has static IP. And then when I view the site from home . it's fine. But when I tried to login, the site is using a pop-up, I guess it's http authentciation, login, I was redirected to a url without my port number any more, that stops my access to the site as obviously I would.
How can I keep my connection/port number ...?

Network Design / VLANs Design
Apr 9, 2008We are co-located at a datacenter and host web sites, and corporate email systems, as well as host dedicated servers for customers.
We currently have two /25 internet facing subnets from our provider. We have a Watchguard X5500e 8 port gigabit firewall that supports routing as well as VLANs. We also currently own QTY4 2848 HP Gigabit switches.
We currently have each switch connected in a loop with 2 gigabit ports trunked using static LCAP. The switches are connected as follows:
A > B
B > C
C > D
D > A
Rapid STP is turned on. One thing is - is this the ideal trunking scheme?
The more important question is this. We would like to separate ips from each other using VLANing.
IE: we might have a client with 5 different IPs in one or more subnets and we would like to group them together.
We ideally do not want to break up the subnets into smaller ones as it makes it hard to reconfigure and it wastes ip addresses, as we do not have that many.
FTP Only On Port 21
Apr 23, 2008I am using proftpd...How do i instruct that the server don't listen on high ports 49152-65534 but only to 21?
The reason is because my client's firewall setup is very strict and i need to give a good reason to open those high ports. Right now, i can ftp to port 21 only but can't do nothing more than that coz the higher ports are blocked.
What's My SSH Port
Jun 24, 2009i now have root access at a site i manage and the previous admin has set up a different SSH port.
I think this because i get " Connection Refused " and that user has access for SSH.
When restarting my SSH services i recive;
Quote:
sshd has failed, please contact the sysadmin.
And from looking that error up it means the port has been changed.
So i have WHMC access and all other root passwords etc, but how can i find out the port?

Apr 16, 2009I know this is a bit of an odd question but I have a VPS which has port 1189 open. Is it normal by default to have this port listening on a OpenVZ VPS under HyperVM? or is this something a little concerning?

It's most probably nothing to be concerned about, just wanted to double check.
