Anyone have experience using mpd-netgraph? I'm trying to use it for my freebsd box so that it can act as a VPN server. I have it installed no problem and it seems to work in a limited scenario. Let me try to explain. boxa--------- 10.0.0.2 | 10.0.0.1 24.219.x.x |-------------FreeBSD_GatewayBox-------------INTERNET | boxb--------- 10.0.0.3 Okay, from a microsoft box out on the internet I can directly authenticate to my BSD box with no problem. This is a box that has a public IP, so there is no natting or anything weird like that going on. But, when I try to authenticate to my BSD box at home going through a box on a private IP addy, say 1.2.240.x that is gnatted through the public it will not connect. I have no other problems connecting to the BSD box from the natted address, either through SSH or telnet..anything of that nature..no problem. So here is my question, and I don't know much about PPP or PPTP and how the packet is put together, but, does ppp operate like tcp packets...using src and dst port? If so, then my PPP connection is never going to get established 'cause the router doing the natting doesn't know where to send the PPP packets...or...am I way in left field. I just don't understand why I can't connect from a box being natted to my machine at home when I can if I'm on a box with a public. Any help would be appreciated. Thanks!
