Hi. After my ISP decided to switch to PPP only, I had to move from bisdn with raw HDLC to i4b with sppp. Installation was a breeze, I was pleasantly surprised with the bisdn torture still fresh in mind. My configuration: 486 PC running FreeBSD 2.2.6-RELEASE, Teles 16.3 non-PnP card, i4b 0.63. The problem we are now experiencing is that isdnd does not hang up after idletime because there is constant lcp echo traffic between the ppp server on the isp's side and isppp. The debug output from isppp0 shows Aug 12 09:50:43 firewall /kernel: isppp0: lcp input(opened): <echo-req id=0x21 len=12 22-f6-d9-74-0-6-3f-7b> Aug 12 09:50:44 firewall /kernel: isppp0: got lcp echo req, sending echo rep Aug 12 09:50:44 firewall /kernel: isppp0: lcp output <echo-reply id=0x21 len=12 35-d9-ec-9c-0-6-3f-7b> every ten seconds. Corresponding to this tcpdump -i isppp0 gives 11:15:58.249799 [|ip] 11:15:58.249859 [|ip] I have read the recent discussion of this in the list archives, but there was no solution mentioned. I suspect that if isdnd is responsible for the hangup timeout, it should ignore these packets, or alternatively the timeout should be handled by isppp. Any ideas? Thanks, Guido -- Guido von Walter .
