Pop3 thru sonic wall
Posted on 2004-08-22
Previous setup: Windows NT Exchange 5.5, direct one to one NAT translation with external IP address thru Sonic Wall Pro 200 with Field Salespersons accessing email thru pop3 request from exchange server.
1.Installed Symantec Gateway for SMTP
2.Changed direct NAT thru Sonic Wall to point at SMTP Gateway
3.Installed DNS Server on Domain
4.Created rule to open port 110 thru Sonic Wall (POP3 request to LAN)
All works fine except POP3 accounts cannot log in.
Sonic Wall Pro 200 does not have a direct port forwarding option, that I can find, to point POP3 requests directly to the exchange server and bypass the SMTP Gateway and their tech support is in India.(They have been helpful but the language barrier is difficult and I do not know if they exactly understand my issue)
