Hi Joe, You're welcome. The flip side of Linux's arp funkiness is that you can get it to do some nifty stuff. For example, a /32 ethernet looks more or less like this: ifconfig lo:1 198.51.100.1 netmask 255.255.255.255 ifconfig eth1 192.168.0.1 netmask 255.255.255.252 ip route add 198.51.100.44/32 dev eth1 src 198.51.100.1 arptables --out-interface eth1 -j mangle -s 192.168.0.1 --mangle-ip-s 198.51.100.1 The implicit proxy arp takes care of the rest with the machine hanging off the interface thinking that it's part of a /24. This sort of thing is how I'm using all 17 of the IP addresses in my Cox /28. :-) Regards, Bill Herrin -- William D.
