TCP can't be confused in this fashion; it does not make the connection from 5900 to 5900, but instead makes it from (temp port) to 5900. All packets would be sent back to (temp port) on the viewer machine or tunnel-machine. Even if somehow this were happening, I would get "failed connection" messages, as NO packets would successfully return -- instead I get a login prompt and successful-connection reports in my logfiles. You can look at NETSTAT /AN and see what I mean. However, in this instance (as mentioned in the other message) the IP address ranges aren't even identical; 192.168.1.* at home, 10.* at work, so the identical-IP stuff doesn't even apply here. Also, just for giggles, I installed a server on BOX_2 and attempted to vNC to it; same problem. (changing the forward from 5900: BOX_1:5900 to 5900: localhost:5900 and 5900: BOX_2:5900, of course). > Even if that is not your situation exactly, try a tunnel that looks > like: > > L5910 <BOX_1 ip address>:5900 <external ip address> I haven't used the IP addresses yet. I suppose I should try that and see what happens, although for DNS or reverse-DNS to be the problem here would be very weird. (I have changed the local ports, remember: tried it on 9876 and 5631, specifically.) -- Derek _______________________________________________ VNC-List mailing list [EMAIL PROTECTED] To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
