I could and have done it another way...that's to shut all the servers down in one box and start all the servers back up in the other box and tweak the dns server in both boxes but it's just easier and simpler to just shut one box down and bring the other up. now then..no, I do NOT run nat...since I only am using 1 static ip(209.205.179.141), I just have my dns server(s) do it all. I have both machines serving dns by using a "split" dns server. my config file for each is set up in "views" inside and outside. both the dns servers are basically the same. the zones are tweaked to point to their respective machines and the static ip points to the box that it's running on. lol now to confuse this issue more lol, my slave server set up in my 2 dns systems is my ip. I know that traffic is coming in #53 because of the notify and reply back from my slave when I change the sn on zone files. hope this clears that point up for ya. thx for your interest, Bob. john rose -- The only times my computer fails to come on is after I shut it off.
