PPTP VPN
by Sérgio Cioban Filho - TECJUMP
Olá galera,
Estou com um problema, tenho um servidor com FC4 e instalei o PPTP para
VPN, até ai tudo bem,
eu conecto com clientes Rwindows e eles ficam no ar, mas quando conecto
com um cliente linux, a conexão fica caindo a cada 2 mimnutos.
OBS.: Para me conectar no rwindows eu tenho que desmarcar a opção
"Exigir criptografia de dados" .
Tem algo de errado??
Alguem pode me dar um ajuda??
Segue os confs e LOGs:
