Radius Authentication to Server Remote from VPN Endpoint
Hi,
I have users who dial-in to an ASA and authenticate via RADIUS to a server at Site A. There is a heavily used site-to-site VPN between site A and Site B. At site B there is another RADIUS server used to authenticate users who dial-in to Site B.
The RADIUS server at site A has gone down so I've added the Site B radius server to the AAA server groups but I'm unable to successfully authenticate across the site-to-site VPN. I've tried adding explicit firewall rules as packet tracer indicates that the failure is due to the implicit ACL but still won't connect.
Any idea how to achieve this?
Thanks.

Hi,
Yes it is IAS and the ACL defines the inside-network/24 to remote-network/24 which includes both the ASA's inside interface address and the remote network entire subnet.
I can't ping the remote server from the ASA, so probably one and the same issue.

Upgrade of the IOS seemed to fix it, thanks.
Will RRI work on networks where you are not using a routing protocol?

Reverse route injection is primarily designed for VPN tunnels, so no routing protocol will be required. Routes get installed once the tunnel is up
Can you ping the RADIUS server at site B from ASA command line? Most probably, the interesting traffic does not include the firewall itself.
