I'm using the latest v2.rc6, Linux (SLES9) and iptables on the server
side, Mac OS 10.3 client side. The general connections work pretty
well, but I have trouble opening multiple connections to the same
destination address & port to a machine behind the VPN.
The mail application on Mac OS X is heavily threaded and establishes
multiple connections to the mail server in parallel, because I've got
two accounts on the mail server, and it also establishes parallel
connections for downloading attachments and so on. When I connect
through the OpenVPN tunnel some of these connections never gets
established, but the "main" connection works fine. I have this problem
over both UDP and TCP tunnels. When close the tunnel and connect
directly to the mail server the problem disappears again. Is this a
known problem, and how can I go about troubleshooting it?
