Pro jistotu přikládám konfiguraci klienta:

port 80
tls-client
proto tcp-client
dev tap
route-delay 5
pull
comp-lzo
verb 3
ca \\ca.crt
cert \\client1.crt
key \\client1.key
comp-lzo
persist-tun
persist-key
verb 3
resolv-retry infinite

77.77.77.77 je veř. adresa serveru 10.10.10.1 je vnitřní adresa serveru 10.10.10.2 je vnitřní adresa klienta kde se tam pořád bere ta další IP vůbec netuším

Díky za jakékoliv popostrčení
