As part of a remote-access trial, I have configured a PIX-515e as a PPTP server, and dial in users can successfully connect to the corporate internetwork through it. However, the dial in users cannot access the Internet, as the PIX firewall does not allow packets to leave by the same interface (ouside in this case) as they entered. Can the PIX be configured to allow this, or is not worth the increased security risk?
