On the Windows clients I am using OpenVPN-gui (https://openvpn.net/community-downloads/ - OpenVPN-2.6.4-I001-amd64.msi)
I have already tried to add a rule to the Windows firewall to allow anything to come in or go out from port 1194.
This is the server configuration:
Server config
port 1194
proto tcp
dev tun
ca ca.crt
cert FZ01SRVR.crt
key FZ01SRVR.key
dh dh.pem
server 10.10.10.0 255.255.255.0
client-config-dir ccd
push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS 208.67.222.222"
push "dhcp-option DNS 208.67.220.220"
client-to-client
keepalive 10 120
tls-auth ta.key 0
cipher AES-256-CBC
user nobody
group nogroup
persist-key
persist-tun
status openvpn-status.log
log-append openvpn.log
verb 5
This is the client configuration (cross-OS):
Windows client config
client
dev tun
proto tcp
remote xxx.xxx.xxx.xxx 1194
resolv-retry infinite
pull-filter ignore redirect-gateway
nobind
persist-key
persist-tun
ca ca.crt
cert gestionale.crt
key gestionale.key
tls-auth ta.key 1
verb 1

What am I doing wrong?
