i read the FAQ and it says 100 passive ports should be sufficient. my firewall is the Windows Server 2003 RRAS basic firewall, and it doesn't support port ranges so i have to set them one by one
other users have reported success with 10 ports, and i've tried using ports 5000-5010. but i get about 30% success when trying to browse directories or transfer files. is that due to the small port range? i have disabled multiple connections for transfer on the client in an effort to use fewer ports.
the client is using Active mode, with a custom port range of 5000-5010 to match the server, connecting via implicit SSL on port 990.
server firewall has opened ports 20-22, 989-999, 5000-5010.
client router is forwarding ports 20-22, 989-999, 5000-5010 to my client PC.
no matter what i try i can't get a reliable connection. can anyone help?!
really appreciate any tips/suggestions... apart from buying a hardware firewall
