I *think* $ARG?$ is available in post 1.0 but the code is not stable.

Why don't you define the check of the external interface as a service and 
check the internal interface as the host check ?

Firewall is up if the internal interface responds (machine is good)
External interface down - service alert for the firewall admins.
