Ok, some network info ...
I have six remote linux networks to connect to .. All remote sites are running Debian R3.0r1 linux to provide email facilities,etc.
I also have two other sites running Microsoft SBS 2003, again, that I would like to connect to - at the minute we are connecting to these networks via the SBS VPN client ..
To start with I want to link our network to one of the linux networks (a clients). How should I go about this? I have full control over the networks at both ends.
I would like to also enable our LAN to allow our remote engineers to connect over VPN (all our remote laptops run a combination of Debian R3.0 and Windows XP Pro)
Finally, I am completely 100% new to VPN
