Is there a problem with routing the WHOLE subnet? If you where me I'd
probly find the subnets assigned by aron and route them all to the correct
sevice.
Also you could use a script to run 'host' on the name and forward the
result to iptables, but make sure if the host call fails you provide a
descent default. The host cmd could add several minuets to your boot up,
if your name server is not reachable.
