Hello all, I am using netgraph-based pptp and I am having this problem. It seems that there is a problem binding to INADDR_ANY or doing a single connect(2). My source address is given and everything works correctly: >>>>root:zuper:0:~# telnet -s X.X.137.252 X.X.137.252 22 >>>>Trying X.X.137.252... >>>>Connected to ppp-dsl-252.... >>>>Escape character is ^]. >>>>SSH-2.0-OpenSSH_3.8.1p1 FreeBSD-20040419 >>>> >>>>Protocol mismatch. >>>>Connection closed by foreign host. My source address is not given and that's what happens: >>>>root:zuper:0:~# telnet X.X.137.252 22 >>>>Trying X.X.137.252... >>>>telnet: connect to address X.X.137.252: Network is unreachable >>>>telnet: Unable to connect to remote host The problem appears only to the ng interface. The problem appears with other netgraph nodes(/usr/share/example/udp.tunnel for example). It is working correctly on 4.10-RELEASE. Any clues from any experienced netgraph user or hacker?
