Also add:  ppp chap refuse

If you have auth set to either on the Max.

I did this today and it works although I have a problem that needs an
answer too.

interface Dialer0
 ip unnumbered Ethernet0
 encapsulation ppp
 dialer in-band
 dialer idle-timeout 86400
 dialer map ip 203.30.236.70 name mars modem-script dialnum 82321111
 dialer load-threshold 1
 dialer-group 1
 no fair-queue
 ppp multilink
 ppp authentication pap callin
 ppp chap refuse
 ppp pap sent-username zoo-sa password 7 1513081F57233F


This works perfectly.

It brings up two channels.  They form a beautiful little MPP bundle.
If I try and ping the Cisco from the MAX with a packet any larger than
around 1460 bytes the packets get lost.

I have set the MTU on the MAX down to 1200 and I have set a Frame-MTU to a
similar value but it appears the MPP wants to have 1522 byte MTU.

I have slowed the serial ports on the Cisco 2511 to 38400.

I tried setting ip mtu 1200 on the Cisco without any apparent result.

What am I doing wrong?
