I am have setup a temporary ssh server to reverse ssh to remote clients. When a client has an issue I have them reverse ssh to my server and then from my laptop or workststation connect to there workstation. The problem that I am having is when I connect to them from behind my firewall from my laptop the connection is really slow but when I connect to them from the firewall it is fast. I am using Firestarter which is simply a GUI for iptables. I am trying to figure out what iptables rule is causing the connection to slow down behind the firewall. Any suggestions?

I'm not seeing anything that sets off major alarms immediately for reverse ssh, have you tried flushing it and setting up a simple firewall and seeing if the issue still occurs? It might be due to rate limiting somewhere in that config but really shouldn't be. I'd start from scratch and add things back in and see where the problem starts occurring at.
I have resolved the issue. I do believe that firewall definitely play a part in performance issue with remote connections. This has been an issue that has been occurring for years and never really dug to deep into it until today. Essentially is was rather simple and was just thinking about the connection and what the issue was. Of course when connecting to a remote connection via vncviewer you are dealing with typically graphics when connecting to a windows environment. I just reduced what was being sent over the pipe in regards to graphics and configured vncviewer to connect as though I was connecting to a slower connection such as a modem. This is what worked for me via vncviewer.
I'm sorry! I do a lot of remote support, but most of it is at the console, so I never considered you were simply sending a large amount of data. Good job however, and congratulations on discovering a workable solution!
