       lcp-echo-interval n
              If this option is given,  pppd  will  send  an  LCP
              echo-request  frame  to  the  peer every n seconds.
              Normally the  peer  should  respond  to  the  echo-
              request  by sending an echo-reply.  This option can
              be used with the lcp-echo-failure option to  detect
              that the peer is no longer connected.

Subject: [pptp-server] frequent ppp disconnects


My vpn client is frequently disconnecting. It can happen as often as =
every few minutes, but usually it takes more like 15 or 20 minutes. Once =
I was able to stay connected for 3-4 hours before the disconnection, but =
that is the only time I've been able to maintain a relatively long =
connection. I'm using 1.1.2 and pppd 2.4.1 on RH 7.1. I haven't =
installed any of the patches. Other than the frequent disconnects, =
networking works great. How does one track down such a problem? Does =
anyone know the solution? Does anyone think it would (or wouldn't) be =
worth going back to the "stable" build of poptop?

Here's a few lines from /var/log/messages:
