OpenVPN Support Forum

Hello, I set up a OpenVPN-Server in my office. Now I am on holiday and I want to work, but there is no connection possible, when I am using one of the hotels wireless networks. When I am using a hotspot over my mobile phone, it is working.
Have you any idea, what I can do? Thank you very much!

Hi Jad,

Many open hotspots are only providing a web proxy service, not true Internet access. That would mean no UDP connection is possible.

Perhaps when using the same hotspot on your phone, the phone retries via cellular data; that would explain it.

If it's just for you, I would suggest you look at OpenVPN Access Server, which works around this issue by also providing an openvpn daemon on TCP port 443 (https). This solution can expand as your business grows, but for 2 concurrent connections it's completely free of charge.

Of course you can do the same thing with community openvpn as well: simply run a second server instance (with a different network of course) on the same machine.

hth, regards, rob0

Hello rob0, thanks a lot. I choosed the TCP-option, so that UDP cant't be the Problem, can it? I am not able to install the new server in my holidays. Isn't it possible, to change the Open-VPN-Port to 443? Is this the possible solution?

If you are using access server you can use the commands beow to configure the TCP port 443 for OpenVPN service.

cd /usr/local/openvpn_as/scripts/
./sacli --key "vpn.server.daemon.tcp.port" --value "443" ConfigPut
./sacli start

This should enable the TCP port 443 for opevpn tcp daemon.

Hello rob0, sorry about my late reply. It's a familiy holiday, so that I only can work later. Unfortunately the change of the port hasn't solved the problem.

Hi,

Would recommend opening a support ticket at https://support.openvpn.com/ in order to assist you with that concern.
