VPN with Cisco ASA5505 and SBS 2003

[-Jim]

Let me preface this by saying that I am not great with Cisco, I am much more comfortable in the MS server environment but I inherited this setup and am trying to figure it out best I can.

Basically, I am trying to setup a VPN and use my DC as a RADIUS server. Below is my running config (I used the Cisco VPN wizard to attempt to setup the VPN). On my server I got IAS with a remote access policy allowing VPN access when 'NAS-port type match Virtual VPN" and the user is part of the VPN security group.

Here is run config, i changed public IP's, domain name and passwords out of paronia, lol.

I'm not a Cisco expert, sorry. The Windows Event Log can be very revealing when dealing with radius though, have you looked at it yet?

[-Jim]

yah, i dont even see any related events. Which makes me think the ASA is not talking to serve. Which is why i think something is wrong with ASA.

Hi Jim,

I have my ASAs setup to directly query the DC using LDAP, rather than go via a RADIUS server:

aaa-server Windows_LDAP protocol ldap
aaa-server Windows_LDAP (inside) host x.x.x.x
server-port 636
ldap-base-dn OU=xx,DC=xx,DC=xx,DC=xx,DC=xx
ldap-scope subtree
ldap-naming-attribute sAMAccountName
ldap-login-password *
ldap-login-dn CN=xx,OU=xx,OU=xx,OU=xx,DC=xx,DC=xxx,DC=xx,DC=xx
ldap-over-ssl enable
server-type microsoft

The ASDM 6.1 GUI in conjunction with ASA 8.04 is considerably more useful than the v7 stuff you're using, by the way...

Chris.

thanx. Yes, I am in process of updating both ASA and ASDM. I will try again once I get them all updated.
