Re: TCP Problem

[Larry Bolhuis <lbolhuis@xxxxxxxxxx>]

As you describe your specific situation Jon, it sounds like the No
Dafault Route situation. Check CFGTCP option 2 for a *DFTROUTE which
should normally be poiting at your firewall or a router between the
AS/400 and the firewall. Of course this will also prevent any other
access through the firewall to the AS/400 as well.

Also after checking your other posts on this thread, it sounds like you
know the IP address of the PC outside the firewall as it is set up
specifically for testing.  Can you PING that device from the AS/400? 
That should be easier to get working. Also load some freeware FTP server
product on the PC and then connect to it from the AS/400.  Then while
that conection is open, on the PC use the NETSTAT -n command to list all
connections. You should see a connection on Port 21 coming from the
AS/400 and it should claim to be using the public (outside) address
assigned in the NAT table for the AS/400.

Hope this helps!

ps My General success rate with the SonicWall product has been fair to
ptly cloudy.  Good under light loads, worse under heavy loads.
