I'm trying to configure a 2611 router (IOS 12.2) for vpn, so that vpn clients can connect to it.
As of now, my int e0/1 is using the 10.0.0.0/24 subnet, and I also have a dhcp pool that assigns address for that same subnet.
Hence, for the pool of addresses that I define for my vpn group, can the addresses overlap with an existing subnet?.. Or do I have to use an unused subnet?
Please enlighten me.
Thanks in advance.
Use a different pool for VPN Clients.
Use the configuration below as a reference;

hi.. thanks for your sample config, on my second attempt to fix the error.. seems that I should have defined a seperate address pool, and also, I forgot one line, which is client configuration address respond.
Thanks once again.
p/s sorry for voting 2.0.. couldn't change after I solved the problem.
