Linux boxes seem to mostly work with the wrong netmask, but I've seen things that don't. Your subnet broadcast will be wrong. > They would talk to 10.1.16.1-10.1.19.254 ones, but would go for the gateway for 10.1.20.1-10.1.31.254 But the gateway may send an icmp redirect, knowing you should be able to reach the target directly. I'd recommend fixing everything to match as soon as possible. -- Les Mikesell lesmikesell at gmail.com
