SMTP Forwarding 
Some ISPs require their users to send e-mails via the ISP’s SMTP server. All outgoing SMTP connections
are blocked except those connecting to the ISP’s. The Peplink Balance supports the interception and
redirection of all outgoing SMTP connections (destined for TCP port 25) via a WAN connection to the WAN’s
corresponding SMTP server.
To enable the feature, select Enable under SMTP Forwarding Setup. Check Enable Forwarding for the
WAN connection(s) that needs forwarding. Under SMTP Server, enter the ISP’s e-mail server host name
or IP address. Under SMTP Port, enter the TCP port number for each WAN.
The Peplink Balance will intercept SMTP connections. Choose a WAN port according to the outbound
policy, and then forward the connection to the SMTP server, if the chosen WAN has enabled forwarding. If
the forwarding is disabled for a WAN connection, SMTP connections for the WAN will be simply be
forwarded to the connection’s original destination.
Note
If you want to route all SMTP connections only to particular WAN connection(s), you should create a custom rule in
outbound policy (see Section 16.1).
