Many DSL providers do unless you are purchasing a static IP business connection. Verizon Online blocks port 80 in the areas that were formerly Bell Atlantic and some additional areas as well. You could use a dynamic IP redirection service that would redirect requests to your (probably changing) IP and also to whatever port you choose to use. Cheers! John -- John P.

Hi, John, Thanks. Yes, I also suspect that SBC DSL blocks the standard web port 80. I cannot find the info from their web. I use DNSExit dynamic IP updating service with a domain signed up with them. It is pretty good. It is pityful that my web server has to listen to a nonstandard port. John P. Dearing wrote: > antonyliu2002@yahoo.com wrote:

I use no-ip.com for dynamic DNS, and I have no problem accessing apache on my Linux box in Illinois on dynamic PPPoE IP from an external shell account in Texas. SBC only blocks 2 ports related to Windows worms (MS Blaster or Sasser?), and outgoing port 25 other than to their own SMTP servers due to worms that include their own smtp server (port 25 can be unblocked upon request). If you are using a router, maybe there is some problem with your router or its configuration (or if you enabled remote router config from WAN side). Make sure you test it from elsewhere on internet (or dialup), because if you are testing it from another PC on same LAN, many routers do not do loopback (LAN2LAN via public WAN IP). | |||||||||||||||||||||||||||||||||||||||||||

Hey, David, You are right! SBC DSL does not block port 80. This is confirmed just a moment ago, I removed my Linksys WRT54G router and directly connected my WinXP box to the DSL Modem. Then I changed the IIS listening port back to 80. It worked! Hmm, what do I need to do to Linksys WRT54G router so that it does not block port 80? Thanks.
