Phillip, I would have concurred and would have given Mike instructions on addressing had not the traceroute that he provided let me know he is behind some router doing NAT. > You not sure your cable modem doesn't a Router built in His cable modem probably does have a router built in. I was a bit alarmed when I first saw his message, but since I was asking for a traceroute anyway, I figured that I would learn the actual situation before alarming Mike. The first hop in the traceroute was 1 * 10.133.140.1 (10.133.140.1) Most likely that is the IP of his modem/router. It is possible that that is on the other end of the line, which means that in the worst case, Mike is exposed to all other Virgin Media customers using that same router. That wouldn't be good, but it is certainly much better than having his machine connected directly to the public Internet. Mike, would you mind taking a look at your cable modem and telling us what the make and model is? Then we will be in a better position to advise. Also, the only machine in your house is your Mac, then go to System Preferences > Security > Firewall and check the box to block all incoming connections. Then go to Sharing and turn everything off. Depending on your answer to the make and model of your cable modem, I and others here will advise you to purchase a very simple router. I don't know what they cost in England, so I'll leave it to others here to make specific recommendations, but if you don't have any kind of internal network or wireless, the absolute simplest and cheapest thing will do. (my previous posts in this thread were probably more in line with me representing Agile Web Solutions. Now I'm just being me.)

Good luck with fixing the problem. -- Danny T

That's not much help I'm afraid. -- Mike Lane UK North Yorkshire email: mike_lane at mac dot com

But I am in the > south in London Thanks, Mark. That is very helpful. What appears to be a single DNS server (like the ones that both your and Mike were using) may often be several that are geographically distributed. This makes the actual cause of the problem even harder to track down. Cheers, -j -- Jeffrey Goldberg http://goldmark.org/jeff/ I rarely read HTML or poorly quoting posts Reply-To address is valid |
