I've got a Cisco 3005 VPN concentrator that I'm trying to set up for\nPPTP connections. I'm pretty sure that PPTP is enabled, and that it's\navailable as one of the protocols for all groups. And it's being\nallowed through the public filter on the public interface. But when\ntrying to connect, I get "no answer" errors. Is there any other\npossibility for me to check other than there might be packet filtering\ngoing on somewhere upstream?\n\nThanks!
