[FUG-BR] VPN pptp caindo

[Mario Lobo]

Alô a todos.

Tenho a seguinte situação:


FBSD Firewall vpn server com poptop, autenticando num AD 2008 como RADIUS.

A VPN fecha bonitinha. Pingo toda a LAN direito.

Porém, quando tento alguma coisa mais pesada, como acessar o exchange 2008 
(OWA) via web pela LAN, a pagina inicial ate carrega, aparece a lista dos e-
mails mas antes de completar a carga da pagina, o tunel cai:

Jun 13 13:44:24 AllenFW ppp[1987]: Phase: Radius(acct): START data sent

requirement)
