I must add tons of subnets (in the xxx.xxx.xxx.xxx/xx format) to the IPsec policies. I am on Windows 2003 servers.
It will take forever to add them one by one...
It's almost 500 subnets.
Is there an automation script or...?
to configure a VPN connection between two Cisco Routers.
I have the configuration in one side but for another side I have nothing.Is any one can help me about it??Another question is :are two routers need to have a valid IP or not?
secure a windows server 2003 traffic.
I have one server with a small number of clients <10. The clients have dynamic IPs.
The server hosts a number of public facing websites, email, FTP and remote desktop.
What I want to do is make port 80 respond to all web requests but lock all other services down so that they only respond to my 10 clients. I was thinking some certificate or VPN solution but I've ruled VPN out as I don't have a firewall or VPN so would I be able to do this with IPSEC?
Is there quick utility that would do this or can you point me to a good example article?
Is it possible to use IP Security policies in Windows Server 2003 to help prevent types of DoS attacks? Today my server was attacked by a single attacker who merely connected and disconnected on open ports at an incredibly fast rate. This was enough to eat the cycles of the server processes effectively creating a DoS attack. I was hoping IPSec could help prevent this, but I'm open to use any other software as well.

I can enter IPs manually but unable to ban an entire RANGE of ips
i.e. For example 172.10.10.10 - 172.1.1.999
Anyone know?
I'm trying to establish a VPN server inside a Fedora 10 VPS under OpenVZ. Openswan or Poptop is preferred over OpenVPN because Windows has built-in support for these protocols.
It looks like the host node (it's actually the vps from myprohost.com) doesn't have the required kernel modules enabled(installed?). Take Poptop for example, if I run pppd after rpm installation, the output is like this:
[root@v ~]# /usr/sbin/pppd
/usr/sbin/pppd: This system lacks kernel support for PPP. This could be because
the PPP kernel module could not be loaded, or because PPP was not
included in the kernel configuration. If PPP was included as a
module, try `/sbin/modprobe -v ppp'. If that fails, check that
ppp.o exists in /lib/modules/`uname -r`/net.
See README.linux file in the ppp distribution for more details.
[root@v ~]# modprobe -v ppp
FATAL: Could not load /lib/modules/2.6.18-92.1.18.el5.028stab060.2/modules.dep: No such file or directory
And when I check for the availability of the encryption module "MPPE", I got the same result:
[root@v ~]# modprobe mppe
FATAL: Could not load /lib/modules/2.6.18-92.1.18.el5.028stab060.2/modules.dep: No such file or directory
Openswan complains about some missing kernel modules too. So what do I do? Do I tell the provider to enable these modules? Do they normally do that? Will the host node require a reboot after having done that?
What modules are required for Poptop and Openswan? And, do I need to tell them to re-enable these modules every time I rebuild my OS?
