Solved: ppp authentication chap pap callin or pap chap on my Dialer interface?

erik.doss · ‎10-17-2007

Does it make a difference which order the authentication is in if I have both the pap and chap user name s and passwords applied to the same interface? Should I have pap first of chap first? Here is my current setup:

DSL modem --> Ethernet0

vpdn enable

vpdn ip udp ignore checksum

!

vpdn-group pppoe

request-dialin

protocol pppoe

interface Ethernet0

no ip address

ip virtual-reassembly

full-duplex

pppoe enable

pppoe-client dial-pool-number 1

no cdp enable

interface Dialer0

ip address *.*.*.169 255.255.255.248

ip access-group 102 in

ip mtu 1492

ip inspect FIREWALL out

ip nat outside

ip virtual-reassembly

encapsulation ppp

no ip route-cache cef

no ip route-cache

no ip mroute-cache

dialer pool 1

dialer-group 1

ppp authentication chap pap callin

ppp chap hostname ****@pacbell.net

ppp chap password 7 ********************

ppp pap sent-username ****@pacbell.net password 7 ******************

crypto map rdln_map

Thanks for any helps!

No it doesn't matter. With both PAP and CHAP credentials configured, whatever the ISP uses, you have, so it's ok.

also:

- you don't need the vpdn statements, the docs referencing that are old.

- suggest you re-enable ip route cache cef

- reconfig mtu to default of 1500 and test "ping x.x.x. df size 1500", chances are it will work

- add "ppp ipcp route default" and "ppp ipcp dns request" to remove need of configure these separately.

hope this helps, please rate post if it does!
