I'm having an issue with the latest version Airport Extreme Base Station (Firmware v. 7.7.3) where I cannot connect to a windows 2003 VPN (RRAS Server). I've bypassed my AEBS, and the connection will go fine (via PPTP), but as soon as I go through the AEBS, it never goes through. Something is being blocked at the AEBS. Has anybody gotten through this issue before? Background: I just upgraded this AEBS to latest version and it was working before on previous version AEBS. I reverted back to that setup, and it wasn't working anymore. Nothing seems to have changed but it no longer works (with new or old AEBS).
