Well the problem is solved, but I am not happy about the solution as it makes absolutely no sense to me. xl0: flags=8943 mtu 1500 options=3 inet 192.246.38.10 netmask 0xffffff00 broadcast 255.255.255.0 inet 208.23.240.10 netmask 0xffffff00 broadcast 208.23.240.255 ether 00:04:75:b0:24:12 media: Ethernet autoselect (100baseTX ) status: active The above was the ifconfig when I had the problem. Notice the broadcast addresses. The commands that brought up the interface at boot are: /sbin/ifconfig xl0 192.246.38.10 netmask 255.255.255.0 /sbin/ifconfig xl0 alias 208.23.240.10 netmask 255.255.255.0 (note that the netmask really is not required as those IP's are from traditional class C, but I like to always be specific so I don't forget one when I'm working in 'A' or 'B' space.) So those commands give two different kinds of broadcast addresses and to my way of thinking, the second one (on the 208...) is correct. But if I alias the interface like so: ifconfig inet 208.23.240.10 netmask 0xffffff00 broadcast 255.255.255.0 The sluggishness on the 208 net goes away. I don't understand it, but it works. I don't like stuff this, it creeps me out. -- Joseph F.
