We have one last problem before we go live with our UC 520 demo unit. I've got it set up as the NAT/PAT router on our network, and all seems to be working fine except for PPTP VPN, incoming and outgoing. I can't connect to any of my clients, and I can't connect in from home. I know this is an issue with PAT, but it's been addressed with the version we're running right? (Version 12.4(11r)XW3, RELEASE SOFTWARE (fc1))
Relevant config attached.
