Sorry -- this is the host I wanted you to ping:

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast
qlen 100
    link/ether 00:19:d1:01:2f:45 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.250/29 brd 192.168.0.255 scope global eth1
         -------------
    inet6 fe80::219:d1ff:fe01:2f45/64 scope link
       valid_lft forever preferred_lft forever

But it DOES exist -- it is your Shorewall box''s default gateway!!!

Table main:

10.100.100.2 dev tun0  proto kernel  scope link  src 10.100.100.1
...
default via 192.168.0.249 dev eth1
            -------------

If you can''t ping 192.168.0.250, then the default route on
192.168.1.140
is incorrect.
