Hi ,


I need to connect two offices ( two different LAN's) together using cisco 1841 routers at both end.


Currently both cisco router are in working order and  acting as a internet gateway to the LAN clients. ( doing NAT).


Can anybody please advise what is the easiest method to configure VPN between two sites so that  LAN users at one office be able to access  the  email/application servers at the other LAN office.


I understand I need IPSec Site to Site VPN  ( i think).


Can anyonce please advise.


Regards.

Yes, you do need a site-to-site VPN. Start with this link which gives a number of examples for configuring a S2S VPN between 2 Cisco routers -
