Re: SBC DSL blocks port 80?

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.

I cannot use port 80 for my web server (IIS 5.1) running on my WinXP
box, but nonstandard ports work great.

No, SBC (now ATT/Yahoo) does not block port 80. 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).
