NAT Problems

Last night, I opened my routers ports that I was told (80,3074,53 and 88), and it still says my NAT is moderate or strict. the UPnP is enabled as well. Any ideas on what to do?

Many issues with this one I'm afraid


The first one is very likely to be down to your chosen ISP, can you go into the status menu of the Clear modem and look at the WAN or Internet IP Address. Does it start with 10, 192 or 172? If so please post it up, if it starts with anything else please only post the first part of it, i.e. 62.129


If the WAN/Internet IP Address does with 10 or 192 or 172 then your ISP is providing you with a private ip address not a public one, which means they are already NAT'ing your connection before it gets to you. You could ask if they can supply a public ip address.


Ideally you only want your Xbox connection NAT'd once (or not at all)


  1. Your ISP may well be NAT'ing your connection
  2. Your Belkin is NAT'ing again
  3. Then if your sharing your PC connection using ICS (and not bridging) your NAT'ing again


3 * NAT is a big problem. But I'd start with checking what your ISP is giving you for an ip address before doing anything else

Did this solve your problem?

Sorry this didn't help.
