I have no idea what has happened to our system.

We use Redhat 4.2, SCSI aha2940 card, P100, 64 meg SDRAM, Seagate 4.2 gig
HDD, Boca BB2016 16 port serial board, ppp2.2.0g static patched,
mgetty1.1.12-Jan27, and kernel 2.0.33. And, our internet feed is coming in
through a serial port on the serial board.


I tried a fresh kernel install to see if it would fix this problem, but it
didn't do squat.
I have gone through all our settings, and they all are the same as they
were when it was working fine (and no, adding static IP support didn't do
this, it was having this problem before I added it).
The server is working fine in regardes to talking with the internet by
itself. eg. I can ping any host and ftp out to sites, web works fine
aswell, etc. etc..... while at the console or in a telnet session.

The problem is the dialin clients not having a constant route through our
server (or rather our server not constantly routing the packets) to access
other hosts on the internet. They have full access to all provided services
on the server they are dialed into though. They have access to internet
resources aswell, but it is "very" lagged, sometimes to the point of
wanting to puke.

I have our DNS servers automatically assigned to the clients - that's
working fine, AutoPPP is setup and working fine aswell as the patch for
static IP assignment, and the kernel has ipforwarding enabled. Like I said
it was working fine until about a week ago.

The following is what the kernel is outputting after issuing 'dmesg'. Hence
the reason I tried the fresh kernel.

ppp: write frame, count = 8
FF 03 00 2D 1B F1 FA 67 ...-...g
ppp_dev_xmit_lower: fcs is 900f

ANY, and ALL ideas on what has happened or howto fix this, would be
"GREATLY" appreciated! No matter how small, unimportant, stupid you may
think your idea is, Pleas throw it in here.

HELP!

TIA
