Hey guys, Changed ISP to Aussie Broadband yesterday, and suddenly can’t seem to connect to my server using my domain (still can connect in the local network). Aussie Broadband uses CGNAT, and I opted out of that, but I still can’t seem to use the server… am I missing some router settings I might need to change? Any other ideas?

Server firewall is off, ports 443 and 80 are forwarded to the servers nginx proxy manager etc. Using ddns that ASUS provides with their routers and Cloudflare domain

Thanks for any help!

    I have AussieBB and had to give them a call at one point to allow inbound traffic so I could expose my self-hosted server. They flicked a switch for my account and then everything came good.

    If you give them a ring and explain what you’re trying to do it should get sorted out very quickly. Their customer service staff are very knowledgeable and friendly - they’re the best RSP I’ve ever had.

      This was the answer, called up and got them to unblock ports 80 and 443 (they actually unblocked them all). Thanks alot!

      99% this is probably what’s happened. Aussie by default blocks incoming traffic on the usual ports (25, 80, 443, etc.) but will happily remove the block if you give their support team a call and explain why you want the block removed.

      There’s also an option to remove it in their app these days as well I believe. Go to Service Tests -> Port Blocking and you can disable it from there.

        Yep, the app is by far the easiest way to deal with it, and it’s got a great amount of troubleshooting options too.

        Ah that’s great. It wasn’t an option when I had to get it sorted but that was a few years ago. The self-service options in the app are excellent for basic config and troubleshooting.

    Does the A record for your domain match what your IP is right now?

    Sounds to me like your IP changed and your A record isn’t pointing to the proper IP anymore.

    The new ISP would have given you a new IP address. Do you use a dynDNS to automatically update the record? Or do you need to manually update your domain’s DNS service to point to the new IP address?

    Does your new ISP allow 80 and 443? I was under the impression that’s pretty rare for ISPs though I’m not sure that’s true in Australia. Mine only allows 443 but not 80 “to prevent Internet worms from spreading and to protect bandwidth.” 🙄

      At one point my old provider went under and sold their customer base to another provider, and things stopped working for me. I had to convince them I had a reason to open up port 25. I was like dude, I’ve been running mail servers longer than you’ve even been in business.

      They opened up all ports to me.

      Too be fair to your ISP, the only thing you should be using 80 for is redirecting to 443.

        Right, but if I can’t redirect (ISP just drops packets afaict) and you don’t explicitly type https:// or use an https link, and I don’t have something like HSTS preload configured for that domain, your browser will just hang if it’s on my system. You can’t just type “lemmy.stuart.fun” and have it work unless you happen to hit my hairpin, i.e. be on my network.

        Mostly I try to keep things I want publicly available on .dev and it just works thanks to the full .dev HSTS preload. But it’s still annoying.

    I’m on ABB and everything was fine after I called up and got CGNAT disabled and the ports unblocked.

    You can unblock ports in the MyAussie phone app these days.

    And you most definitely got a new IP address. Make sure you’ve updated your DNS. My IP hasn’t changed in over a year. It only ever changed when they upgraded their equipment.

    Did you check whether the new IP assigned are any different. Once it happened that my old ISP had ip range 192.168.0.x. but the new ISP had ip range of 192.168.1.x

    This made my machine not accessible.
