Hi, To summarize, My ADSL modem does NAT. I run vnc server on port 9000 I translate port 21 to port 9000 on the modem My modem was listening from port 21 but I disabled it. I am behind NAT in the office also. I can telnet to port 21 of my modem and I get the RFB prompt of VNC
I did something crazy and put a firewall on my desktop at home. I allowed port 9000 on it and configured it to log everything. When I got back home, I can see all the requests from my office being allowed by the desktop firewall. BUT I still get connection reset by peer (10054) message. Does anybody know how to debug vnc? Any other suggestions?
