Add for my previus post: 

Hello folks
 
I am using m0n0 without any troubles for 6 months. Now I want to use it as
VPN server and client. Here is the situation: I have one Main location and 5
remote ones. SO I want to establish a VPN tunnel from remote to Main site
using m0n0wall. Does anybody has any experience with situacions like this?

Here is a description:

Main m0n0 (VPN1) <> ADSL <> Remote1 m0n0
Main m0n0 (VPN2) <> ADSL <> Remote2 m0n0
Main m0n0 (VPN3) <> ADSL <> Remote3 m0n0
Main m0n0 (VPN4) <> ADSL <> Remote4 m0n0
Main m0n0 (VPN5) <> ADSL <> Remote5 m0n0

Cheers,

Andrej
