Plusnet blocking Open VPN port 1194 TCP and UDP

I recently tried to unsuccessfully to set up an Open VPN server behind my plusnet hub one router by trying to forward incoming connections on port 1194 to my VPN server on my LAN.

 

I found the following problems:

 

1. There is no Open VPN port forwarding rules to select amongst the preset options listed in the plusnet hub one routers menu.

2. I was able to enter 1194 manually for the incoming and local ports, but found that even when I did this and used an open port checking tool that 1194 still remained closed.

3. I also logged into my plusnet account online as there is a firewall option (not to be confused with the firewall on the hub one router) and set this to OFF which should in theory open all ports to the router. Using the port checking tool port 1194 still remains closed.

4. I phoned plusnet technical support who said port forwarding in general is not something they support and were unable to offer any help.

 

Thinking the plusnet hub one router may be faulty or just too restricted for needs I bought a new router, an ASUS DSL-AC68U to completely replace it.

 

Once I'd set the ASUS router up and got the basic internet settings working correctly I went into the port forwarding rules to set up port 1194 again. A port checking tool confirmed that port 1194 still remains closed.

I have tried forwarding other ports like port 5000 TCP and this shows as open with the port checking tool, which confirms that my method for port forwarding is working.

 

Conclusion is that plusnet is just totally blocking any connections on port 1194.

 

If anyone has a different experience or can offer a suggestion please do.

Re: Plusnet blocking Open VPN port 1194 TCP and UDP

I use OpenVPN on PlusNet - I have 1194 UDP open and it works fine.

 Note you have to drop and reconnect the PPP session for the PlusNet Firewall changes to take effect - it could be that.

 

Can you see the connection attempt in your router firewall logs ?

Re: Plusnet blocking Open VPN port 1194 TCP and UDP

My Openvpn server works well via PN.

Port 1194 UDP.

I know other PN customers have had no problem using Openvpn with TCP .

Do you have the plusnet firewall set to OFF or LOW?

 

Will check my logs when I get home

Are you using your own router or the plusnet one?

Re: Plusnet blocking Open VPN port 1194 TCP and UDP

Hi,

I use Open VPN server on a raspberry pi with no issues but saying that I've setup my VPN not to use the default port, so the port forwarding rule has my chosen port and not 1194 and it is set to UDP only.

I'd check the firewall setting in the members centre and make sure it set to LOW.

Home > Member Centre > Connection Settings > Set My Broadband Firewall

Please note most port checkers only check if TCP ports are open Open VPN is usually UDP.

Dan.

My PlusNet firewall is OFF - would rather control it myself.
