I have a problem with my PC NT4.0 and a Cisco1721. I am triyng to callback, and the router not accept the authentication of the PC. The router accept the call, but don´t make the callback. "MCB: Callback not authoriced for this user".
The router configuration is:
logging buffered 32000 debugging
logging console informational
enable password <deleted>
username Softgal01 password <deleted>
no ip name-server
isdn switch-type basic-net3
no ip domain-lookup
interface BRI 0
ip unnumbered FastEthernet 0
dialer map ip 192.168.128.98 name Softgal01 class remaccess 981173772
no cdp enable
ppp callback accept
ppp authentication chap
no ppp multilink
map-class dialer remaccess
dialer callback-server username
interface FastEthernet 0
ip address 192.168.128.1 255.255.255.0
ip nat inside
The active debugs are:
debug ppp nego
debug ppp cbcp
The register of the debugs is:
*Mar 1 00:02:21: %LINK-3-UPDOWN: Interface BRI0:1, changed state to up
*Mar 1 00:02:21: BR0:1 PPP: Treating connection as a callin
*Mar 1 00:02:21: BR0:1 PPP: Phase is ESTABLISHING, Passive Open
*Mar 1 00:02:21: BR0:1 LCP: State is Listen
*Mar 1 00:02:21: BR0:1 LCP: I CONFREQ [Listen] id 1 len 40
I have experienced the same problem and finally got it working with interface BRI. Try setting up router with aaa and username .... dialerstring. Only difference with your situation is that the client PC i'm using has Windows 2000 installed.
The problem with this solution is that i only need one B-channel for callback, but now i have to use the BRI interface for this purpose.
Can't get callback working with dialerprofile, If anyone has a solution please let me know.
I'm not sure what version code you are at, but this could be CSCdw27654, which was a 12.2T bug fixed in 12.2(8.5)T and later code. The workaround is to do the following:
and aaa authorization network local
If you are not running 12.2T code, then you might try as another workaround attempt the command "username Softgal01 callback-dialstring 981173772 password secret"; what is happening is that the IOS seems to think, right from the start, that this user is not authorized for callback.
