OpenVPN through different Port

[webdb]

Hi

I have been using OpenVPN through UDP/1194 since many years now. Unfortunately the company has blocked any outgoing VPN hence I've created a new config using the wizard.
All fine, I've tried UDP 80, UDP 8080, TCP 443, UDP 443 and in all cases I can connect to my firewall but I can't access my home network 192.168.1.0/24

This is regardless of the company firewall, it also happens when I use my mobile as a hotspot.
Only with UDP 1194 I can connect my home network.
I have compared all settings line by line and they are equal (except protocol/port). What else can I do to make this work?

I would really appreciate your support. Many thanks in advance

Show your OpenVPN Config and Firewall Rules (Screenshots).

Thanks Rico

As requested, screenshots attached. As client I use Viscosity with exported inline configuration. No Change on the client itself. any other files / screenshots needed, just let me know

You can't have 4 OpenVPN Server active sharing the same tunnel network.
Disable three of them and try again.
You should stick with UDP...

Ahh, didn't know that. I will try that today when I'm back home

UDP is my prefered protocol for that but unfortunately blocked by the company hence TCP....

MANY THANKS

They completely block or sniff into UDP packets?
You could maybe get around it by enabling TLS Encryption, depending on what they do.

I'd disable the UDP/1194, TCP/443, TCP/8080 Instance, enable TLS Encryption for UDP/8080 - restart the Instance and give it a try.

In some companies, that can get you fired. Many companies have strict policies on what you can do with THEIR network.

I'm with user @JKnott here -- do you hate your job there? Do you want to perhaps receive disciplanary action or even get terminated just so you can use a VPN on the company's network and on the company's time?

I don't know your specific company, but they have likely blocked VPNs for a reason and may not take kindly to attempts by you to circumvent the restriction. At the Fortune 500 US company where I worked what you are attempting on a first offense would at a minimum get you time off without pay to reflect upon your actions. And a second offense would get you an escorted trip to HR and then the parking lot -- permanently banned (as in terminated).
