Using an alternate source IP address for specific destinations
Normally, locally originated IP packets use the IP address of the outbound IP interface as their source address.
However, when using VPN tunnels there are situations, where locally originated IP packets must be sent using
the source IP address of an alternate interface. You can specify using the following command that for one or
more destination network the IP address of an alternate IP interface should be used. This configuration com-
mand affects all locally originated IP packets except those, which originate from explicitly bound components
like SIP and H.323.
