I run a four machine network here at home, 3 are windoze boxes, with the fourth running FreeBSD 227-RELEASE. I run usr PPP with the -auto -alias switches, and it works extremely well as the gateway for the other boxes. I can successfully build a PPTP tunnel if I do a straight dial-up from the windoze boxes into any of our terminal servers. However, if I attempt to tunnel through the FreeBSD box, it gets past verifying username and password, and then errors out with "network not responding". It appears PPP is not passing mickysoft's GRE protocol 47, as in the tcpdump below as the connection is made: (FreeBSD):/etc/ppp> ping 204.170.16.6 PING 204.170.16.6 (204.170.16.6): 56 data bytes 64 bytes from 204.170.16.6: icmp_seq=0 ttl=123 time=156.393 ms 64 bytes from 204.170.16.6: icmp_seq=1 ttl=123 time=150.196 ms 64 bytes from 204.170.16.6: icmp_seq=2 ttl=123 time=130.257 ms ^C --- 204.170.16.6 ping statistics --- 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max/stddev = 130.257/145.615/156.393/11.151 ms (FreeBSD):/etc/ppp> tcpdump -i tun0 -n tcpdump: listening on tun0 07:48:49.222167 192.168.0.3.1138 > 204.170.16.6.1723: S 45394131:45394131(0) win 8192 < mss 1460,nop,nop,sackOK> (DF) 07:48:49.360187 204.170.16.6.1723 > 192.168.0.3.1138: S 84804242:84804242(0) ack 453941 32 win 8760 (DF) 07:48:49.360979 192.168.0.3.1138 > 204.170.16.6.1723: . ack 1 win 8760 (DF) 07:48:49.361257 192.168.0.3.1138 > 204.170.16.6.1723: P 1:157(156) ack 1 win 8760 (DF) 07:48:49.600241 204.170.16.6.1723 > 192.168.0.3.1138: P 1:157(156) ack 157 win 8604 (DF ) 07:48:49.601315 192.168.0.3.1138 > 204.170.16.6.1723: P 157:325(168) ack 157 win 8604 ( DF) 07:48:49.810235 204.170.16.6.1723 > 192.168.0.3.1138: P 157:189(32) ack 325 win 8436 (D F) 07:48:49.843613 192.168.0.3 > 204.170.16.6: ip-proto-47 39 07:48:50.005754 192.168.0.3.1138 > 204.170.16.6.1723: . ack 189 win 8572 (DF) 07:48:52.845139 192.168.0.3 > 204.170.16.6: ip-proto-47 39 07:49:00.958484 192.168.0.3 > 204.170.16.6: ip-proto-47 39 07:49:06.157396 192.168.0.3 > 204.170.16.6: ip-proto-47 39 07:49:11.356350 192.168.0.3 > 204.170.16.6: ip-proto-47 36 Any thoughts or helpful advice?
