22.3.1 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. Pepwave routers support
intercepting and redirecting all outgoing SMTP connections (destined for TCP port 25) via a

Service Forwarding
When this option is enabled, all outgoing SMTP connections destined for any
host at TCP port 25 will be intercepted. These connections will be redirected
to a specified SMTP server and port number. SMTP server settings for each
WAN can be specified after selecting Enable.
When this option is enabled, all outgoing connections destined for the proxy
server specified in Web Proxy Interception Settings will be intercepted.
These connections will be redirected to a specified web proxy server and port
number. Web proxy interception settings and proxy server settings for each
WAN can be specified after selecting Enable.
When this option is enabled, all outgoing DNS lookups will be intercepted and
redirected to the built-in DNS name server. If any LAN device is using the
DNS name servers of a WAN connection, you may want to enable this option
to enhance the DNS availability without modifying the DNS server setting of
the clients. The built-in DNS name server will distribute DNS lookups to
corresponding DNS servers of all available WAN connections. In this case,
DNS service will not be interrupted, even if any WAN connection is down.
When custom service forwarding is enabled, outgoing traffic with the specified
TCP port will be forwarded to a local or remote server by defining its IP
address and port number.
