You should re-read "HelpDesk.txt".
I did. It was working, before Telus replaced my old modem (actually a router as well) with a new one. Now, it seems that NO incoming traffic can get through. Alternate ports don't work. I suspect that they have, somehow, blocked the modem from accepting it's own address. Out going is okay, incoming seems to be blocked. Period. I can't even ping my own outside address (not that that means much).
I can make Helpdesk work through my own router, but not through the modem. I even tried my cell phone connection. It is with Public Mobile (which is owned by Telus), and it does the same thing. I can get out, but not in. I haven't, yet, tried to do a direct connection to my brother's computer (he is with Sympatico which is Bell Canada), and I wouldn't be surprised if they block that sort of thing too. It will be a major project to get him to open a port in his modem (especially when I don't know anything about his modem).
Telus was, at one time (when they were Alberta Government Telephones), a leader in internet technology. Now, they can't even run an e-mail server, and they farmed that out to GMail, which is nothing short of a royal pain. Unfortunately, there aren't a lot of options, and most, if not all, of the alternatives are even worse. I am looking at getting a business account, which is, of course, more expensive (but that is why they block things).
BTW... what ever happened to the once-standard advice of "Run checkini"?
Well, I asked my brother to do it, but I don't think he has done it yet. It would be so much easier if I could just go there and fix the problems. The biggest problem is, that he has lived with the problem for a while, without telling me, so going back is probably not an option any more.
