I think I need a NAT solution... right???

[MrGibbage]

I am on Cox HS internet, using DynDNS. WRT54G router. I have a PC that stays on 24/7 (windows XP). I am trying to set up some IP webcams for home security and they have built in webservers, but they can only run on port 80. Cox blocks port 80. The only solution I can think of is to set up a port forwarding rule in the router to forward requests such as mydyndns.org:12341 for camera one or mydyndns.org:12342 for camera two etc to the 24/7 PC. I could run NAT on that PC looking for those specific requests and forward them again to the correct camera. I have looked and looked and cannot find and free/open source windows NAT software out there.

Is there another solution out there? Am I making it too hard? Does anyone know of a good NAT solution for Wondows XP?

Best Regards,
Skip

I might be missing something but how can you browse the internet if your
ISP is blocking port 80? This is the primary HTTP port...

My ISP (Verizon - FIOS) blocks port 80 going to the user, coming from the
use is not blocked. It seemed that Verizon wants to prevent a residential
user from being a server.
(Haven't check recently that this is still the case, it came up when I
wanted to test creating a server with IIS, had to use port 8080 instead)

If I remember correctly:

I used DynDNS to convert name:80 to my IP address:8080,
then use the router to convert 8080 -> 80,
details on how I did that are now fuzzy however


OP wants to have 2 servers, don't think what I did would work for two
servers.

Hi
I the camera send the info via port 80 it is blocked by the ISP and does not
reach to you, so there is nothing that you can do on side to get in
something that is Not existing. Most DNS services provides port redirect
(no-ip.com is an example). I.e any signal that comes to their server from
the outside ion port 80 can be redirected redirect to port 1234 (as an
example) before it reaches the WAN side of the Router
All you have to do is portfoward in the Router port 1234 toward the IP of
the computer that follows up the camera.
This should not effect your regular surfing since regular port 80 action
does not go to your DNS service.
