Here is my situation and setup:
Internet --------Router A----------(E0)Router B(E1)----------LAN
Router A belongs to my ISP and they have assigned my E0 interface on Router B (Cisco 2514) a private (10.0.0.155) IP address. The E1 Interface goes to my lan. The default gateway for Router B is set to the Interface on Router A (10.0.0.1).
I have a public IP and it is on some interface over at Router A and then any thing destined with my public IP gets sent to my Router B E0 interface.
I did NAT so my users can get to the net and I setup port fowarding so my www server will work.
I need to setup a VPN solution here using a Linux box or with the Cisco IOS. I will copy and paste my sh version of the router when I get it, but for now, all I know is that when I look for any vpn commands the only thing I see is VPDN. I don't know if that will work. Also, I don't think I have the IPsec or DES feature pack. Ill copy and paste as soon as I can.
Also if I use a linux solution, does my router need to support ipsec or any encryption?
