Hi GP

thanks a lot.

i would like to know one more thing.

my IOs version is 12.2 - 28a, hope all the commands will work.when you configure PAP or CHAP authentication

do we need to consider the username and password.i mean

the name of central router should be the password of other router something like that.

currently which version of IOS r u using.

Thanks & Regds

Binoy.

[Georg Pauwen]

Hello Binoy,

the configuration is for IOS 12.0, so all the commands should be the same for your IOS version.

Regarding the authentication: the username should be the name of the router, make sure that the passwords match on both sides.

So, for CHAP, the configuration should be:

HQRouter#

!

username BranchRouter password cisco

!

interface Serial0

ppp authentication chap

!

interface Dialer1

ppp authentication chap

BranchRouter#

!

username HQRouter password cisco

!

interface Serial0

ppp authentication chap

!

interface Dialer1

ppp authentication chap

And for PAP authentication:

HQRouter#

!

username BranchRouter password cisco

!

interface Serial0

ppp authentication pap

ppp pap sent-username HQRouter password Cisco

!

interface Dialer1

ppp authentication pap

ppp pap sent-username HQRouter password Cisco

BranchRouter#

!

username HQRouter password cisco

!

interface Serial0

ppp authentication pap

ppp pap sent-username BranchRouter password Cisco

!

interface Dialer1

ppp authentication pap

ppp pap sent-username BranchRouter password Cisco

Can you try and see if that works for you ?

GP

Hi GP

please check the attachments,i think we missed out something.You can find configuration and debug information.Please Check this.

Thanks & REgds

Binoy.

[Georg Pauwen]

Hello Binoy,

I found the following in both your configs:

ip nat inside source list 1 interface Dialer0 overload

Can you change that to:

ip nat inside source list 1 interface Dialer1 overload

and see if that makes a difference ?

Regards,

GP

[binoyjosephstanly]

Thanks GP i will get back to you.

[binoyjosephstanly]

Hi GP i changed that particular line now its

ip nat inside source list 1 interface dialer 1 overload

now its dialing but inteface se0 is doing down.bcoz of some unBIND issue.

please check the attached file, debug info.

thanks

Binoy.

[binoyjosephstanly]

Debug Attachment pls check

[Georg Pauwen]

Hello Binoy,

it looks like for some reason your PPP is not working right. Try and configure your CHAP authentication just as:

interface Serial0

ppp authentication chap

on both routers (that is, take out the rest of the CHAP configuration, such as 'callin).

Which brand of modem are you using ? Can you post the output of 'debug modem' ?

Regards,

GP

[binoyjosephstanly]

hi GP

please find the DEBUG MODEM output

my modem is US Robotics 56k FaxModem

model is 5630B

i will remove the callin and check.will update you.

i'm in big pressure i need to resolve this issue.

thank you very much for your support.

Hi GP

can you please give some inputs regarding this.

Binoy.

[Georg Pauwen]

Hello Binoy,

for some reason your modem is not connecting properly.

Under your line configuration, try and configure:

modem autoconfigure discovery

or type:

modem autoconfigure type ?

and check if your modem type is listed as a modemcap there.

Also, on your serial interface, add the command:

async default-routing

Regards,

GP
