the datacenter where are located my server have a Cisco 3560G 48 port, seem that we have a problem when we add on a port as secondary 5 subnet, it hangup and not all the ips work, the datacenter tech say that can be a bug and 3560G dont support more that 4 subnet as seconday per port is this true? when we have remove the 5th subnet all the ips work fine.

View 12 Replies View RelatedI'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.

I would like to find out from users how they designed and layout their networks when it comes to subnets.
Currently we have 3 subnet's of different sizes which house our network equipment such as Switches, PDU's, Log Servers etc. but also on these same subnet's are servers which we provide web hosting and VPS services. We also have some clients on these subnets with dedicated servers.
I am curious about this network design. Is it acceptable to house our operational equipment such as switches, PDU's etc on these same subnets which has client access servers or should be obtain a small seperate subnet to house this equipment for security and isolation reasons.
My host has helped me to install a switch. However, I don't know how to configure using the command line. Could anyone help me?

View 1 Replies View RelatedI 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 ...?

in your experience,do they really be different?

We are looking to replace our existing WatchGuard Firebox's with a hopefully more reliable firewall from Cisco's range although I'm a bit lost when it comes to the different ranges.
Could somebody suggest a firewall that is capable of:
1: Both NAT & Drop-in (bridge) mode
2: Pretty low bandwidth requirements, no more than 10mbit/s traffic
3: SNMP Monitoring
4: High availability pairing
I am on a tight budget for a Cisco firewall. I am browsing and seeing some affordable options in the x600 series.
Please tell me, which series is best?:
1600
2600
3600
The higher the better?..
Also what about submodels, like is 1650 better than 1600?
And how can I tell how much DRAM each one can take up to?
I see a lot of DDos related articles here at WHT. We've got hit multiple times by DDos and had to handle those attacks everytime with a different approach.
The largest one and the most well know one (we were in Times Mag, AP news, CNN, slashdot, you name it - just do a search about us on WHT) was Russian botnet cyberattack - we had to anaylyze netflow and then block everything on our edge routers, then on the firewall and then locally on the servers.
Since then we had number of other attacks, some of them we were not able to defend on the server level, while, as you can understand we can't do netwflow and manual intervention evey time somebody gets an attach.
We have very good scripts which allow to mitigate huge number of DDos attack, whet our scripts are finding attacking IPs and blocking them automatically - still some attacks could be blocked only on the router level.
I've read that Cisco Guard (I am interesed in 65xx version of it) suppose to mitigate DDos attacks in automatic mode.
after months of disruption moving servers into a new data centre, our once reliable colocation company has now had nearly 6 hours downtime in the last 16 hours. So much for network redundancy.

What is the difference between the Cisco PIX and Cisco ASA Firewall Systems?
Also which firewall do you guys recommend for a rack of servers
I am currently looking at these Cisco switches:
- Cisco 2924 WS-C2924-XL-EN Enterprise Switch
- Cisco 2950 WS-C2950-24 Catalyst Switch
- Cisco 3512 WS-C3512-XL-EN Enterprise Switch
- Cisco 3524 WS-C3524-XL-EN Enterprise Switch
- Cisco 3548 WS-C3548-XL-EN Enterprise Switch
1) I was recommended to chose the XL-EN model switches because it seems they have more Memory, but the second one in the list (Catalyst) is not a XL-EN, is that going to have any affect performance wise? or it doesn't really matter?
2) I was also recommended to choose managed switches because that way I can use the SNMP features to measure bandwidth, are any of the switches above unmanaged?
3) I also want to be able to manage the switch remotely, web managed, are any of the switches above web-manageable?
4) Most importantly, when my datacenter give me a 100mbit drop, I dont know which port to plug it in in the 29** series. In the 35** I see it clearly but I am not able to see it in the 29**, any ideas?
5) On some of these switches I see a special port called "Console", what is it? where does that connect to?
6) Do any of the switches above not have a console port?
My network currently looks like this :
ISP ->> L3 Switch ->> Firewall (Transparent Mode) ->> Switch ->> Servers
I have a single /24 and my firewall is on x.2 and routes traffic for each of the servers.
Now i have a new Cisco ASA 5510 that i want to replace the aging firewall currently in place, however i dont want to put the firewall into transparent mode because i dont want to lose all the functionality.
Now with most firewalls your outside subnet cannot be the same as your inside subnet, which is fine if you are using NAT but i dont want to NAT. I need all of my servers to remain with their public ip addresses.
So what is the ideal way to setup something like this? Request my ISP give me a /30 for the ASA outside interface or something? And then ask them to route my /24 through the /30 new subnet?
whether I can grant a specific vlan priority over all other traffic..and if so does anyone know an appropriate site where I can find documentation on how to do so?
