Hi -
I have a persistent problem at a site that's masquerading a 5-node
LAN through a linux box running 2.0.34 with ppp 2.2.0f and an
external ISDN TA.
The connection is established just fine, and works. However, when
used from one of the inside machines, it will work for a short
amount of time (<5 minutes; usually only 1-2 min.) and then dies
with:
Jun 25 16:03:45 foo pppd[1713]: Excessive lack of response to LCP
echo frames.
Jun 25 16:03:46 foo pppd[1713]: Hangup (SIGHUP)
Jun 25 16:03:46 foo pppd[1713]: Modem hangup
Jun 25 16:03:46 foo pppd[1713]: Connection terminated.
Jun 25 16:03:46 foo pppd[1713]: Exit.
The masquerading -does- work until the connection drops, and the
logs show nothing strange (additionally, the firewall script is in
use in about 20 boxes without trouble...). This is bizarre....
I have tried adjusting MTU/MRU to no end, and can find nothing
wrong. Turning up debugging on pppd shows nothing but the
unanswered LCP EchoReq's. I also have the output of 'tcpdump -i
ppp0' if anyone would like it - I don't want to litter our lists
with that unless somebody can extract something useful from it.
I'm pretty stumped here ... any help is greatly appreciated...
-Joshua
