Port open in FW but not getting through

girkers

I am pretty sure it use to work but it isn't working any more.

I have port 2083 open in my firewall from my LAN so that I can get to cPanel on the Internet, but my computer cannot get there no matter which host I try and connect too.

Doing a packet capture shows that traffic is getting from my network to the host but all I am getting is:

On reflection something that might have changed is I have generated and installed a Let's Encrypt certificate, but that is about all I can think off.

Any thoughts?

Thanks

Hi
As far as I can see , the remote host for some reason immediately resets the connection. It is possible that the firewall is incorrectly configured on the remote host (port 2083 is closed)

You mean you have to perfect, anti shoot in the food LAN firewall :

?

I can access your cPanel just fine :

what makes me think nothing is wrong on your cPanel (VPS/server) side.

The cert used isn't from Letenscrypt, it's issued by PostiveSSL, on behalf of cPanel organisation.
No issues neither.

You do receive some packets back - the first two lines, but then your 43.25x.14x.1x port 2083 just stops answering.
You triggered some IP based protection on the cPanel side - like x times wrong logging attempt ?
Use another WAN IP (that's finally a reason why a VPN can be useful) ?

If I use my phone I find that I can connect, it is only from when I connect from my local network that I have the issue.

I will raise the issue with my Hosting provider and see how I go.

Thanks for confirming it isn't me.

Well I feel like a right Id10T,

I found in my firewalls I have a rule that allowed me on the required ports, however I had the source as LAN address, so when I changed it to LAN net, it works a treat.

DOH!
