We have a problem with a PIX Version 6.3, we have a PPTP tunnel, and the tunnel establish from one computer from the LAN to a router on the outside. The PPTP tunnel is OK but we can't ping or RDP the elements in the VPN. May be the GRE ?
We have tried from one other LAN behind an ASA5505 and it's working ! We can see the PPTP and GRE sessions from the syslog on the ASA.
Please .... Help !
