[Fedora-users-br] PPTPD - Problemas

Sexta Março 3 19:02:16 UTC 2006

Olá galera,

Estou implementando um servidor de VPN com o PPTPD, até ai beleza.
Com os clientes Rwindows, eu conecto normalmente na VPN (sem
criptografia), mas com um linux Desktop FC4 com o pptpclient 
dá uns erros e não conecta. Já tirei todas opções de criptografia.
Alguém tem uma ajuda?
