Smtp Forwarding; Web Proxy Forwarding - peplink ONE One User Manual

SMTP Forwarding
Some ISPs require their users to send e­mails 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 E nable under S MTP Forwarding Setup . Check E nable Forwarding for the
WAN connection(s) that needs forwarding. Under S MTP Server , enter the ISP's e­mail server host name
or IP address. Under S MTP 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.
If you want to route all SMTP connections only to particular WAN connection(s), you should create a custom rule
in outbound policy (see S ection 1 6.1 ) .
Web Proxy Forwarding
When this feature is enabled, the Peplink Balance will intercept all outgoing connections destined for the
proxy server specified in W eb Proxy Server Interception Settings . Then it will choose a WAN
connection according to the outbound policy and forward the connection to the specified web proxy server
and port number. Redirected server settings for each WAN can be set here. If forwarding is disabled for a
WAN, then web proxy connections for that WAN will simply be forwarded to the connection's original
destination.
