I am currently installing a Cisco PIX 506e Firewall. I tested the unit in a lab environment and was able to access the pix firewall over pptp with the PIX outside interface configured as DHCP. I was also able to enable vpdn on the outside interface. I implemented the PIX at a production enviroment. The only difference was that the outside interface on the PIX had to use pppoe(static) to access the internet. I was able to allow the local area network users to access the internet, but ran into a problem with PPTP being unable to enable vpdn on the outside(public) interface while using pppoe. Does anyone have a fix for this problem? Your input would be much appreciated.
