Help
I set up a tunnel, but OpenVPN Connect frequently reconnects automatically.

OpenVPN Connect log:
Session invalidated: KEEPALIVE_TIMEOUT
Client terminated, restarting in 2000 ms...
SetupClient: signaling tun destroy event

The problem turned out to be trivial: port 3389 was blocked in Opnsense.

I can connect to RDP via IP address, but not via DNS name.

Help, I've set up OpenVPN Road Warriors.

The PC that acts as a client connected to the VPN can ping the local network, but it can't connect to the server via RDP.
The local network has an AD server with DNS and DHCP.

Thanks everyone!!
I set up a VPN
I should have thought of that

A client specific override is mandatory for a site to site OpenVPN to work if the tunnel network is bigger than a /30.

Thank you!!

Could this be the problem?

I don't understand how it works and how it is connected
Common name - test-client

The problem is that the server can't ping the client's network. The client pings without problems

I had it by default. I indicated it on the first screenshot.

No restrictions

The photo is small, you can't see anything

No restrictions
It still only works one way

On the OpenVPN interface you have to open the source for the remote sites LAN.

It's not quite clear. Go to Interfaces - Port assignment - Add the created VPN as an interface?
In the rules - Assignment specify LAN

Can you show me your configuration?
Maybe I made a mistake somewhere

Looks like it's not a configuration error
Check firewalls on all devices

Help with firewall settings. I don't quite understand either.

The settings are the same on both OPNSense

Please help me in solving the problem.
There is a network shown in the attached diagram.
There are three OPNsense routers in it.
There is an OpenVPN tunnel (172.16.1.0/24) between routers site1-gw and site2-gw, and the same tunnel between routers site1-gw and site3-gw (172.16.2.0/24).
What should I configure so that the computer in Site 2 can access the computer in Site 3 and vice versa?
At the same time we can't set up another VPN tunnel between Site2 and Site3 for administrative reasons.

Can you show me your configuration?
Maybe I made a mistake somewhere

Help. I can't figure out what the problem is!

VPN tunnel 10.0.2.0 is set up. I can ping Serv4 from Serv3, but not vice versa
