Multiple dialin connections using PPP

[Charles Steaderman <charlies@poliac.com>]

I am using PPP on RedHat Linux 6.0 to allow up to 4 dialin connections
to our company and provide a connection to the Internet. I have a
DigiBoard PC/Xe 4 port serial card which seems to be working fine. I can
dialin to any on of the 4 phone numbers and can get to the Internet with
no problem. The problem occurs when 2 or more connections are active.
Only one of the connections can get to the Internet. The other
connection(s) send data (shown on the client modem monitor and verified
by looking at the modem) but no data is transmitted back to the client.
Route problem? Here is the output from route when multiple connections
are active (ppp0 and ppp1). Any ideas?

[root@server /var/log]# /sbin/route
