FreeRadius & BSDi 4.2

I have compiled FR on BSDi and got it working. But I seem to be having a strange problem. Once Auth. users can't go anywhere. They get a IP# and a gateway addy. (Our Modem Racks gives that out - USR Total Control). When you try to go to a webpage 99% of the time it just times out. So we turn off FR and turn on the old radius server, and everything is fine again. Has anyone seen something like this before? Edward Rempala WorldNet Access
