Hiya
My ISP uses DHCP to allocate IP numbers, so currently every time
the IP changes, I have to manually change my firewall rules.
I've just been looking into the 'me' option for ipfw:
me matches any IP address configured on an interface in the
system. The address list is evaluated at the time the
packet is analysed.
Since the machine is a gateway, it has two network cards. Will
'me' match *both* IP address or just the first one it comes
across? I only really want it to match the IP address of the
external interface, not the internal one.
Cheers,
--Jon
