Solved: VPN between 2 Cisco 1841 routers ( LAN to LAN)

s.nasheet · ‎12-01-2009

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 -
