My thinking is that even with it properly configured internally the outside world couldn't see me without my previous router being on the same ethernet (?). Additionally, the /28 subnet was never set up properly and I was concerned about that. Dan, I turned off routed per your suggestion--(I didn't enable it in the first place) I was aware from your previous statements that there could be problems with it although I don't know the details of why.. So I changed all the ip #s and put in for modifications with the Internic last night. Luckily the important ones when through for today. (Although I don't understand why a couple others got the "need human eyes" junk! :( ) Again, thanks all for the advice! Riley
