I'm unable to use the windows VPN client via Fusion to connect to our corporate RAS 2003 Server, and even the Mac VPN Client fails to connect. The windows client (XP Pro) connects and passes the password verification phase but then times out. I'm using Fusion in NAT mode.
I've searched the forum, but haven't landed anything that resolves this issue.
How is your MAC Connected to the internet ?
if you're using a router check it has PPTP / IPSEC pass-through features needed to support vpn connections
Did you tried in bridged mode instead of NAT ?
If you're using Wifi, be sure to install the airport update release at the end of July.
It will prevent your mac to be disconnected from the network.
(not exactly related to this topic but it might help you )
I'm connecting using a Cable Modem that goes out to Comcast, DHCP based. The Internal network at home has an Airport Express that works just fine when I use my Windows machine to VPN out (exact same settings) to the same corporate VPN server.
Tried with bridge mode as well...same issue...
