When an interface name appears in the second column of an entry in
/etc/shorewall/masq, Shorewall will detect all hosts and subnets routed
through that interface and will masquerade traffic from those hosts and
subnets.
This is slightly more general than what I posted recently on the users list
since it uses the routing table rather than the IP configuration of the
interface.
Example:
/etc/shorewall/masq
eth0 eth2
[root@gateway root]# ip route show dev eth2
192.168.1.0/24 scope link
192.168.10.0/24 proto kernel scope link src 192.168.10.254
[root@gateway root]# shorewall restart
...
Masqueraded Subnets and Hosts:
To 0.0.0.0/0 from 192.168.1.0/24 through eth0 using 206.124.146.176
To 0.0.0.0/0 from 192.168.10.0/24 through eth0 using 206.124.146.176
