You say the wan interface uses 192.168.157.254/31:
that gives you a subnet of this range 192.168.157.253-192.168.157.254
and you configured M0n0 to use the gateway 192.168.157.100 ... this gateway
is in another subnet , wich is not accesible from your range.

are you sure your subnet is really a /31 ? this is not a useful subnet since
your first address is the network and the last the broadcast .

Objet : [m0n0wall] WAN interface problems


Hi.

I'm installing m0n0wall on a Soekris net4501 system with 3 eth interfaces.
I connected an ADSL router to the WAN interface, but I can't ping it.
If I try to ping the router IP address from the m0n0wall web interface I
get a "No route to host" answer.
I succesfully can ping the WAN interface of m0n0wall from a PC on the LAN
interface.
The WAN interface is configured with 192.168.157.254/31 IP address and
192.168.157.100 gateway, and the ADSL router is 192.168.157.100.
If I connect the ADSL router to the OPT1 interface of m0n0wall (which is
the sis2 interface of the Soekris) i can correctly ping it. On the WAN
interface it doesn't work anymore.

How I can try to solve this problem?

Thank you very much and goodbye.
Mattia Martinello
