Hello,
I am a network admin for a small company and am looking at a problem: I need to find a solution for our employees connecting from different locations around the world, to our company LAN, one way or another.
We have been using PPTP (as built-in in windows) thus far, but our problem is that people sometimes make connections from subnets that match our subnet (the "192.168.0.x problem") and we cannot really afford to change either. I have read that setting up a VPN-like solution trough IPSec would overcome the problem. Is this true?
I understand there are some issues like certificate deployment, but I do not believe this could be a problem considering the point that all company computers start their life in my office. I am not too eager to go for any extra commercial solutions and am hoping to be able to use what we already have (windows server ISA / windows XP workstations).
Can IPSec tunnels also be used to link LANs (two LANs filled with workstations, same subnet, two machines used as gateways for N-way communication)?
Thanks for any help in advance.
