hello,

I'm trying to implement ipsec vpn site-to-site tunnel. My scenario is:

LAN1--- Linux GW --- ADSL Router (NAT) ---INTERNET--- ADSL Router (NAT)---Linux GW---LAN2


The ipsec tunnel should be between the two Linux Slackware GWs.

Is there anyone how can help me with this implementation? Any tutorial?

Thanks.
