RE: [PLUG] setting up a server: comcast, squid, port 80/8080

[<edward.pike@thomson.com>]

I have setup simple webservers for at least 2 friends
on comcast so i dont think they block it.

in order of preference I would check:

1 - the dydns address really points to your assigned IP.
    (could it have changed?).  most problems of my friends
    is this, half the time.
2 - port forwarding from the outside.e.g., the router wan ip
     1.2.3.4:80 to
    the inside machine 192.168.1.x:80.  if you suspect 
    80 is blocked work try other services (e.g., ssh 
    just to see if you get any response from the outside..
    even a prompt) for awhile with the appropriate port forwarding.


I dont know what dansguardian is; apache i wouldnt be concerned
too much about but I think you NEED to be careful about squid (not to open
it to the outside world).

Subject: [PLUG] setting up a server: comcast, squid, port 80/8080
 
Over the past week I've been experimenting with Linux and setting up a
home network. I started out by setting up a firewall, using ip
forwarding to do NAT. Then I put up squid and dansguardian to do content
filtering. Then I started playing with DNS services on the same machine.
Now I've discovered dyndns and I'd like to have a web server going. 

Everything works fine until I try to get to my site from a machine
outside of the lan. I guess the short question is: does Comcast block
port 80? Is that why my connection is refused outside the lan? Can I use
port 8080 to get around this? How do I set things up on my end so that
apache listens on 8080? Part of my confusion is that I'm not sure how
apache, squid, and dansguardian work together. So should I really be
worrying about what apache listens to or should I be worried about my
forwarding rules? Or should I be worried about one of the other
services?

I'm hopelessly confused here. Someone straighten me out.
