Can't forward port 443

[kaeini]

Hi, so I'm trying to migrate my reverse proxy setup from BT to Virgin Media. But no matter what I do, port 443 seems to always be closed.

I've managed to forward port 80 successfully but 443 seems to always remain closed.

I've tried:

• Disabling the firewall
• Disabling uPnP
• Forwarding the port I used for port 80 to port 443.
• Resetting the router
• Using different external ports for 443.

Nothing seems to be working and I have no idea why. Guidance would be appreciated!

test hub in modem mode no need for forwarding ports which if port 443 work its a hub router mode problem

So basically if I want to forward port 443 then I'd have to get a new router and put the hub in modem mode?

If it works in modem mode then yes

What router could you recommend for me to test it then? Many thanks for your help!

UPDATE: Got a new router and flashed OpenWRT onto it. Still the same issue with every other port working fine.

Absolutely stumped, may have to call Virgin Media to see if they haven't intentionally blocked the port for some reason.

Use this

RJL Software - Software - Utility - Port Listener

Might this help your research?

Thanks but what I don't understand is that this setup worked perfectly fine under BT.

But when I moved my server to Virgin Media, everything broke. It has just left me confused and wasting hours trying to troubleshoot what the issue is.

I would do but I use Linux primarily, not sure if it'd work under WINE. Every website I've checked has stated port 80 (and in fact any port I tested that hasn't been blacklisted explicitly by Virgin Media) has been forwarded properly. But 443 is not getting forwarded for some reason.
