OpenVPN – Cannot ping server computer from client

I am trying to get my OpenVPN setup working for our remote office.

I've installed the OpenVPN community to server and client, created the certificates. Port forwarding rules are also in place, and connection between client and server can be made without a glitch.

But when it comes to ping the client from the server or vice-versa, I got no luck.

I've tried to temporiarly disable firewall for both server and client, but no dice.

Both of the systems are running on Windows (7 on server, 10 on client). I'm using OpenVPN GUI v11.14.0.0.

Here are my slimmed down versions of config files:

Server:

port 1194
proto udp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh2048.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
keepalive 10 120
tls-auth ta.key 0 # This file is secret
cipher AES-256-CBC
persist-key
persist-tun
verb 3
explicit-exit-notify 1

Client:

client
dev tun
proto udp
remote xxx.xxx.xxx.xxx xxxx
resolv-retry infinite
nobind
persist-key
persist-tun
ca "ca.crt"
cert "client.crt"
key "client.key"
remote-cert-tls server
tls-auth ta.key 1
cipher AES-256-CBC

If relevant, here is the active routing table on the client, listed while VPN is connected:

I feel that this is a problem of routing, but I have no clue about how to fix that.

UPDATE 2:
I've just noticed that if I try to ping the server (10.8.0.1), number of bytes out which is show on the OpenVPN GUI increases, as ping packages being sent.
