Hi.

I'm trying to set up two linux routers as firewalls. 

I was wondering if there was any way of *directly* telling if a kernel
has been built with IP_FORWARDING and/or IP_FIREWALL?

The reason is that the forwarding works on one of the routers but not
the other and I think their using the same kernel. (I copied it
across)

However, Its hard to tell if the IP_FORWARING is there simply by using
ping etc since it could be a host of other routining and networking
issues.

TIA.
Cheers,


Javy
