On the subject...

Anyone know how to deal with the flip side of that?  Let's say I have a NAT
router which serves a mini-network with DHCP - any way to update the
firewall (iptables in this case) based on the DHCP allocations?  In other
words, I need to set the *new* destination for the forwarded packets based
on their DHCP address, which while it's usually steady, could technically
change whenever :-)
