The broadcast addresses > should both be 208.70.104.255 for the shown prefixes and netmasks. Hmmm... thats my bad. I have a fsck-up in my rc.conf on that box... ifconfig_re0="inet 208.70.104.210 255.255.255.192" ifconfig_re0_alias0="inet 208.70.104.211 255.255.255.255" I guess when one leaves out the 'netmask' keyword, the next parameter after the IP becomes the broadcast address. I'm actually quite surprised and perplexed as to how this box has been able to communicate to other prefixes on the network :) Thanks for the keen eye. You've most certainly saved me some future anguish! Steve
