I've this issue: I've configured a VPN on my private network at work. Is all configured on a ISA Server 2006. When I try to connect (trough VPN) with a PC I have not problem. With the same configuration (and the same ISA Server rule) on my MacBook I cannot ping to any internal servers. Note: all works fine! I can navigate over internet, i can do everything on external address but if i try to ping (or simply connect) to an internal machine, the connection fails. Someone have some ideas? Thank you.
Ok I've found solution..... As I told yesterday, I've changed the IP range of my DHCP Server (to 10.0.0.xxx) and now I can make ping to my VPN (192.168.1.XXX). Probably the solution was also to make a route via terminal, but I don't know how!!!
Anyway... now it's working and I'm happy!!
