OpenVPN / VirtualBox - why is there no ping between client and server?

Question

openvpn

Hello.
There is a host, it has 2 virtual machines with Astra Linux. On one, the OpenVPN server is up. The "internal network" mode is set between the machines, the IPs are registered, the ping between the machines passes.
There is a task - to proxy all traffic from one virtual machine through another.
The client connects to the server, but the ping fails and after a while the client disconnects.

server log - https://www.pastebin.com/PxyhxVBv
client log - https:/ /www.pastebin.com/JgtTE83j

Removed tls-auth from working configs, didn't work with it.
Run ufw disable on both machines.
Thanks

I solved the problem by commenting out the line, but still it is not possible to proxy traffic - the client does not see the Internet
