I'm assuming you've got a recent > version of ppp (see http://www.FreeBSD.org/~brian). Actaully, I am trying a recent version: ppp-971105. According to the manpage, the log option was supposed to be 'TCP/IP', which didn't seem to do anything. But I tried your suggestion above [lower case], and got some results: My netblock is 198.175.254.0. My gateway is, as by convention, 198.175.254.1. I tried telnetting out from another of my boxes (198.175.254.7) offsite, which failed with a timeout. # grep 254.7 /var/log/ppp.log Jan 21 01:11:05 numachi ppp[12123]: TCP/IP: OUT TCP: 198.175.254.7:4714 ---> 199.0.65.125:23 SYN seq:21e2ce00 ack:0 (0/40) Jan 21 01:11:11 numachi ppp[12123]: TCP/IP: OUT TCP: 198.175.254.7:4714 ---> 199.0.65.125:23 SYN seq:21e2ce00 ack:0 (0/40) Jan 21 01:11:23 numachi ppp[12123]: TCP/IP: OUT TCP: 198.175.254.7:4714 ---> 199.0.65.125:23 SYN seq:21e2ce00 ack:0 (0/40) Jan 21 01:11:47 numachi ppp[12123]: TCP/IP: OUT TCP: 198.175.254.7:4714 ---> 199.0.65.125:23 SYN seq:21e2ce00 ack:0 (0/40) It _looks_ to me that my PPP process _is_ getting the packets, but never sees anything come back. I'll poke at my ISP to double-check thier routing, but if have any further suggestions, by all means, please send 'em down... -- Brian Reichert reichert@numachi.com 37 Crystal Ave. #303 Derry NH 03038-1713 USA Intel architecture: the left-hand path
