Hello Friends,
As you can read in the subject, I have a PPTP client using NAT being unable to connect to the ISA Server. With a public address there isn't any problem.
What ports should be open trough the firewall/proxy? I've read something about NAT-T; how can it be enabled for outgoing PPTP VPN? I know PPTP uses TCP port 1723 and IP protocol 47, but what is needed to be configured in the proxy to let it through?
Thanks,
Max.
