I did intend to set the netmask up as it appears, and it was working for me earlier as I said. Besdies, my internal clients are functioning just fine with the same netmask so unless there is some requirement I don't know about, I don't see why the netmask is an issue. I am hoping that the info I got recently can help shed some light on matters. Thanks again for your help.
