VNCviewer and Proxy Connection Issue
 

I am having trouble remotely connecting to clients behind my Squid/Dansguardian proxy server but if I am on the proxy server or the firewall I can connect fine.
I have a basic 192.168.3.0 network and wanted to know if Squid/Dansguardian actually blocks ports which I though the firewall did? I have a feeling that it is DANSGUADIAN that is causing the headache. VNCViewer, Rdesktop and other remote programs, what type of MIME do they use or is it just ports that I need to be concerned about?

Seek confirmation from Iptables "-j LOG" target rules and logfiles?
