Linksys router inappropriately doing NAT

Right, so I've got this little linksys BEFSX41 here. As one would expect, it's being used for NAT/PAT between the private IPs and the public IP. I have discovered a rather annoying "feature", though. It's translating plain text IPs that are in IMs. So, for example, I IM a co-worker "Hey, test this for me - http://192.168.3.99/blargh.html". He receives "Hey, test this for me - http://123.123.123.123/blargh.html". Obviously, that's incredibly shitty and gay and not really going to work.

I'm searching for a way to turn this off, but am not finding it so far.

It's also possible that it's MSN Live Messenger doing it as it seems to only be happening through Live Messenger, but due to the info needed to be doing this, it seems far more likely that it's happening at the router.

    Turns out this is an msn related issue according to some more knowledgable people than me. If anyone knows of a way to turn this crap off in msn, let me know.

    I think it's very unlikely that the linksys is doing deep packet inspection for the text string of your IP but only in windows messenger traffic.

    I'd guess a messenger "feature" - you sign in, it sees your public address, "helps" you out by translating a private to a public.



    Edit:
    shoulda previewed...

    Yeah, am pretty sure it's messenger at this point. When I initially wrote that first paragraph I hadn't verified that it was only happening in msn, so figured it was either some stupid feature or possibly really fucking poorly written nat code (although it's probably using iptables). I had other people test with msn messenger and it wasn't happening for them, which led me to believe it was the router being stupid. More investigation is pointing at msn, though.

    It's technically impossible for the router to accidentally translate your text messages, since the IP in them would be ASCII encoded (or worse) and wouldn't look anything like the IPs that it's translating on purpose. So unless some programmer intentionally wanted to mess with the people using his router software, it's definitely an MSN problem :0)
