Although the connection appears to be established and isdnd reports being in state 3 only LCP packets are seen in the dump apart from incoming smtp connections which are then rejected by sendmail because it fails to do a DNS lookup on the sending domain. I never see a request going out on port 53 at all. I have tried this with all sorts of ipfilter combinations and ipstat does show packets being passed but tcpdump does not see them, not even the 22 pings. 564 pass out quick on lo0 from any to any 0 block out quick on isp0 from any to 127.0.0.0/8 0 block out quick on isp0 from any to 192.168.0.0/16 0 block out quick on isp0 from any to 172.16.0.0/12 0 block out quick on isp0 from any to 10.0.0.0/8 2 pass out on isp0 proto tcp from any to any keep state 1736 pass out on isp0 proto udp from any to any keep state 22 pass out on isp0 proto icmp from any to any keep state Is this a normal exchange taken from tcpdump -iisp0 21:02:24.692312 ID-106 LCP: Configure-Request, Magic-Number=248067122 016a 000a 0506 0ec9 3432 21:02:24.717650 ID-136 LCP: Configure-Request, Auth-Prot PAP, Magic-Number=1391823577, Multilink-MRRU, Multilink-ED, Link-Discriminator 0188 001f 0304 c023 0506 52f5 8ad9 1104 05f4 1309 0144 454d 4f4e 3117 046f a3 21:02:24.717684 ID-136 LCP: Configure-Reject, Multilink-MRRU, Multilink-ED, Link-Discriminator 0488 0015 1104 05f4 1309 0144 454d 4f4e 3117 046f a3 21:02:24.719774 ID-106 LCP: Configure-Ack, Magic-Number=248067122 026a 000a 0506 0ec9 3432 21:02:24.742030 ID-137 LCP: Configure-Request, Auth-Prot PAP, Magic-Number=1391823577 0189 000e 0304 c023 0506 52f5 8ad9 21:02:24.742054 ID-137 LCP: Configure-Ack, Auth-Prot PAP, Magic-Number=1391823577 0289 000e 0304 c023 0506 52f5 8ad9 21:02:24.742102 ID-107 PAP: Authenticate-Request, Peer-Id=rannoch, Passwd=XXXXXXX 016b 0013 0772 616e 6e6f 6368 0663 3533 6177 67 21:02:24.906921 ID-107 PAP: Authenticate-Ack 026b 0005 00 21:02:24.906968 ID-108 IPCP: IP-Address=0.0.0.0 016c 000a 0306 0000 0000 21:02:25.002296 ID-007 IPCP: IP-Address=MY.IP.ADDR.ESS 0107 000a 0306 9e98 01de 21:02:25.002325 ID-007 IPCP: IP-Address=MY.IP.ADDR.ESS 0207 000a 0306 9e98 01de 21:02:25.004671 ID-009 c02b: 0109 000a 0106 52f5 8bf9 21:02:25.004683 ID-109 LCP: Protocol-Reject 086d 0010 c02b 0109 000a 0106 52f5 8bf9 21:02:25.006912 ID-108 IPCP: IP-Address=MY.IP.ADDR.ESS 036c 000a 0306 9e98 6e75 21:02:25.007002 ID-110 IPCP: IP-Address=MY.IP.ADDR.ESSB 016e 000a 0306 9e98 6e75 21:02:25.030171 ID-110 IPCP: IP-Address=MY.IP.ADDR.ESS 026e 000a 0306 9e98 6e75 21:02:28.603673 ID-001 LCP: Echo-Request, Magic-Number=1391823577 0901 000c 52f5 8ad9 0158 2960 21:02:28.603699 ID-001 LCP: Echo-Reply, Magic-Number=248067122 0a01 000c 0ec9 3432 0158 2960 21:02:38.679219 ID-002 LCP: Echo-Request, Magic-Number=1391823577 0902 000c 52f5 8ad9 0018 03a9 21:02:38.679249 ID-002 LCP: Echo-Reply, Magic-Number=248067122 0a02 000c 0ec9 3432 0018 03a9 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isdn" in the body of the message
