Changed ISP and server now unreachable

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!

pHr34kY,

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.

Salix,

Did you update your public IP address for your domain after changing ISPs?

Vector,

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.

beppi,

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

Drusenija,

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.

Vector,

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.

railsdev,

CGNAT, A records, usual ports blocked by default

Aussie Internet sounds like a real shitshow

cory_lowry,

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

Lightning66,

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.

Those are internal ranges.

Should have paid for upgrade to a 10/8

flubba86,

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?

VelociCatTurd,

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