Is it possible to write a firewall rule for a router with one interface
with multiple aliased ip
addresses that will grab pkts based on the IP_alias they are routed in
or out on, rather than the src or des address of the pkt.  It looks as
tho the 'via' qualifier lumps all the aliases for an interface
together.   I would like to grab pkts, not based on the src and des
contained in the packet, but rather based on which IP_alias it is going
to be sent out on.

Thanks for any insight,
Rick Norman
