I have a serious problem with my institute's firewall. I have a Rackspace Cloud server instance that is configured to accept SSH connections on port 6xxx. When I was using port 22 there wasn't any problem; but when I switched to port 6xxx I cant connect using SSH. This is probably about our institute's firewall policy, as only the ports below 1024 can be listened by root processes on *nix. Is there a trick I can use to connect for once? I will add a MAC-based rule to allow my device.
Edit: I'm using iptables on CentOS 5.x
Best regards, Deniz
