I can successfully remote logon to the secure Aventail network set up by our campus group.  Using a laptop from work I can get  the qws3270 to connect.  With my PC at home I cannot.  Is there a procedure to troubleshoot why
the qws3270 cannot connect?  I can telnet with this connection but I need the emulator also.

Check the setup of qws3270 to see what port it's using.  The default is 23, which is also used by telnet. Since telnet is working, maybe they changed it.  Check what port you laptop uses at work.

If it's different than 23, then you probably need to have your Network Administrator add it to the firewal/access list to allow access.

port should be 10023.  I have the windows firewall turned off.  I use only Mcaffee virus and Adware.
I use a router.  Should I have port forwarding set up?

Are you saying that from home the laptop works but the PC doesn't?

You should only need port forwarding in you home router to allow inbound connections.  You router should allow outbound connection on any port and return packets should be allowed.

Try this , Open a command prompt (Start > Run > cmd) and enter the following

telnet w.x.y.z 10023  ( where w.x.y.z is the remote IP)

Hav you tried turning off McAffee.  I had a strange problem with Windows Remote Desktop not working and found it to be Norton's Internet Worm protection. Maybe something similar with McAffee.


> port should be 10023.

I'm sure you've confirmed that the emulator is configured to use that port right?

Another thing you could try on the PC is the install Ethereal www.ethereal.com (or any other packet capture tool) and monitor the connection process when you try to use the emulator.  With that you can see the outbound and inbound packtes and what ports they are using.

Cheers,
Gary
