USER MANUAL 
Peplink Balance Series 
 
To enable the feature, select the Enable  check box under SMTP Forwarding Setup. Check the box 
Enable Forwarding for the WAN connection(s) that needs such forwarding. Enter the ISP’s e-mail server 
host name or IP address and TCP port number for each WAN.   
The Peplink Balance will intercept SMTP connections, choose a WAN with reference to the Outbound 
Policy, and then forward the connection to the forwarded 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 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 Section 14.1). 
 
20.3.2 Web Proxy Forwarding 
 
 
When this feature is enabled, the Peplink Balance will intercept all outgoing connections destined for the 
proxy server specified in "Web Proxy Server Interception  Settings", choose a WAN connection with 
reference of Outbound Policy, and then forward them 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, web proxy 
connections for the WAN will be simply forwarded to the connection’s original destination. 
 
20.3.3 DNS Forwarding 
 
 
 
When DNS Forwarding is enabled, all clients’ outgoing DNS requests will also be intercepted and 
forwarded to the built-in DNS proxy server.
