Cisco ISDN to Windows RAS ISDN
Posted by SkY on March 31st, 2005


Hey all

I've been trying to set up my 3660 router to use 8-port ISDN BR
interface card to dialout to external ISDN which has Windows 2000 RA
dialin servers. So, when i try to dial from Windows computers wi
dial-up, Cisco BRI answers correctly, and connection is established
When I try reverse, Cisco to dial via BRI, connection fails t
establish. These are my settings, so can anyone tell me please, i
this type of connection is doable, and if it is, what's wrong with m
setup

I try to connect to remote network by simple pinging of hos
172.16.200.

Thanx a bunch

Cisco setup


interface BRI3/
no ip addres
encapsulation pp
logging event nfas-statu
dialer pool-member
isdn switch-type basic-net
no cdp enabl

interface Dialer20
description tes
ip address negotiate
encapsulation pp
dialer pool
dialer idle-timeout 6
dialer string xxxxxxxxxx
dialer-group
no peer default ip addres
ppp pap sent-username xXxXxXxXx password 0 xXxXxXxX

ip route 172.16.200.0 255.255.255.0 Dialer20

dialer-list 1 protocol ip permi

Then,

I've turned on debugging on Cisco, so I can see what's going on

debug ppp negotiatio
debug ppp authenticatio
debug ppp erro
terminal monito

And, this is what I get

And that's it. As for the Windows machine, RAS doesn't even recogniz
the User/pass negotiation..

Thanks fotr your time :
