Problemas na Implantação do OpenVPN
Salve galera blz...
Pela primeira vez estou criando uma VPN e para isso estou utilizando o OpenVPN em modo Bridge
Seguindo alguns exemplos que achei na internet e aqui no site tambem, consegui criar alguns arquivos de configuração.
Aparentemente o serviço OpenVPN no linux esta rodando, o firewall esta liberado a porta 1194...
Porem não estou conseguindo concluir este projeto, não sei se falta algo ou se fiz alguma coisa errado, por isso peço a ajuda de voces.
Desde já agradeço a atenção.
Problema que ocorre no client windows
connect to 201.26.146.180:1194 failed, will try again in 5 seconds: Connection timed out (WSAETIMEDOUT)
Distribuição utilizada
OpenSuse 11.0
OpenVPN GUI v1.0.3 - Client Windows
OpenVPN 2.0.9
OpenSSL - Para gerar os certificados
