Need help in IOS VPN Server with XAuth

r.docuyanan

Level 1

I have this set-up

LAN---ROUTER---WWW

I have a new router and tested the IOS VPN server with VPN Client 4.0

with the settings below I was able to establish a

vpn connection using local database

aaa authentication login USERAUTHEN local

aaa authorization network GROUPAUTHOR local

but setting the following

aaa authentication login USERAUTHEN group radius

aaa authorization network GROUPAUTHOR local

I was not able to establish a VPN connection

The Radius is working fine since my PIX is using also XAUTH and was able to connect

I already add the client in my win2k03 IAS server 2600 as a new client with key cisco.

I still cannot connect please help

What IP address did you use when adding the vpn router to the RADIUS server? If you used a hostname instead, what ip address does the hostname resolve to. I noted that the radius server resides off of the 192.168.1.0/24 network, so it could be that the router is using the fa0/0 ip address, but the win isa server is expecting another.

I would look there first. If the address is defined correctly, then double check the keys, and then turn on aaa debugging on the 2600 to see what messages appear during the x-auth for vpn users.

Let me know what you find.

Hi,

Its so puzzling, I just reboot the router and it worked. IOS is sometimes crazy.

Best regards,

RJ

What model of router and what version of code are you running?

I am glad to see that it is working now, but I found it odd that a reboot fixed the issue.
