Hi there,
Got a small problem, hopefully someone can dig me out! At home I have my NTL SACM hooked up to a Linux (RH9) box that shares the internet,files and printers to other machines on my network here.
Since the server is on the whole time and I was fed up with NTL's email service, I registered my own domain and setup my Linux server as the MX.
This has worked fine for the last 12months or so, but now outside hosts cannot reach the server and mail ends up getting diverted to the backup MX. This isn't a problem in itself as fetchmail still works in picking up email from the backup server, but I do like to be able to login from work and check my email, this can't be done since I can't get through! There's also a webserver running on port 80 (although there's nothing there apart from a welcome note) and SSH on 22. None of these can be accessed. Here's a tracert from centralops.net
Code:

Now. Does this mean that there's something wrong on my server, or at the Woking UBR? I've checked my server settings pretty extensively and I don't believe that it's a problem with iptables, but I can post the settings here if it's not a UBR problem. Anyone else in the area have any similar problems?
Cheers guys,
