Hi,
We recently updated our NetScreen 5GT firewalls from 5.0.0r6 to
5.2.0r2. Now we discovered that one of our customers can't connect anymore to a VPN server inside our network (Windows 2003). According to
formatting link
behaviour in the way PPTP traffic gets passed has changed, but I don't really understand that document. Here's our network layout:
Internet | | Firewall 1 | | Firewall 2 | | W2003 Server
Both firewalls are NetScreen 5GTs with 5.2.0r2. The first is in bridge (transparent) mode, and the 2nd does NAT using MIPs. Both have policies configured to allow TCP port 1723 (PPTP) and IP 47 (GRE).
Anybody got a tip?
greetings and sorry for the horrible english, markus
