Re: Can someone please explain this dialing error?

hello nathan,

As far as I know, LCP is a Link Control Protocol that provides a method of
establishing, configuring, maintaining and terminating a point-to-point
connection. Before any network-layer datagrams can be exchanged, LCP must
first open the connection and negotiate configuration paramaters. This phase
is complete when a configuration ack as been both sent and received.

So.....

suggests there is a protocol problem.

 It is not an authentication problem because that stage hasnt happend yet.

do what fault finding you can on the hardware. If you have not had these
problems b4, and you havent changed your configs in smoothwall (double check
them... I found the defaults work quite well). Try a different serial cable,
or a different modem. then if that doesnt fix it you might also try a
different RJ-12 patch to the POP.

I hope that helps to narrow down the cause.

Jason Civetta
