Port Forwarding on Eir FTTH F5366s modem

Hey,

Getting started with my unraid server and trying to follow along with this video for setting up nextcloud https://www.youtube.com/watch?v=id4GcVZ5qBA

But as you can probably guess from the title Im having some issues with port forwarding and the Eir FTTH F5366s router. So in the video the goal is to get nextcloud.my.domain to resolve to <public_ip>. Then we should send requests on port 443 to my unraid server on port 1443 for my swag reverse proxy to handle.

Ive tried a couple of things, but to no avail, wondering if anyone here has had some success and could point me in the right direction.

I tried setting up a DynDNS using cloudflare and running that on unraid

I tried setting up the DynDNS duckDNS on the router itself, but that always has a status of error and I cant access router logs in maintenance menu as manual would suggest I should be able to https://www.eir.ie/opencms/export/sites/support/.galleries/pdfs/support-pdfs/user_manual_f3000.pdf

I tried adding the following port forwarding rules, one I want and one with a higher port in case 443 was reserved or something. I can hit the <local ip>:443 and get to swag, but not using public IP. Havent touched firewall, DMZ, etc.

Anyway, any help would be greatly appreciated, my friends best advice was to use this url: https://www.virginmedia.ie/ but unfortunately not an option right now

That looks OK to me. I assume you've tested it from another connection? (and not by looping in on the public IP on the same network?) By the way, switching to Virgin Media would make things worse as you wouldn't even get a routable external IP!

That's not correct regarding Virgin Media - you can request to be put on an IPv4 address rather than the DS-Lite IPv6 they use as standard.

Have you tried briefly turning off the firewall on the router to see if the port-forwarding works properly?

Yes but you have to request it and it depends on who you get whether they'll action it or not.

Well now I feel like an idiot, yes I had been trying to hit the public IP from my PC on the network, just tried it on my mobile network and landed straight on my expected splash screen. Seems I still have some SSL issues to fix on port 443, but thats major progress, thank you guys so much for the tips.

Thats gonna suck though not being able to use a domain resolving to my public IP to reach services on unraid from within my network, that a weird eir config or can that be changed?

I’m not familiar with that router but it needs to support loopback NAT so check for that option. Some domestic routers just do it (looks like this one doesn’t) but business grade firewalls need it specifically configured.
