RADIUS Configuration

We have deployed a pair of BIG IP VE's in our lab as a proof of concept, and I am in process of getting these to work.

 

I am configuring remote-RADIUS authentication, which wasn't working. I looked at the /var/log/secure and saw that there were errors stating "All RADIUS Servers failed to respond". In order to troubleshoot I logged on to the console and tried to ping the RADIUS server and noticed that the self IP I had assigned to one of the application VLAN's is seemingly not able to find the route out. The message I get back is: "From 192.168.4.4 icmp_seq=33 Destination Host Unreachable"

 

I am quite certain that this is because of a misconfiguration somewhere on my part, and can use some guidance.

 

Thanks.

    Assuming "192.168.4.4" is an IP address on your BIG-IP, you might want to ensure that the BIG-IP is on the same VLAN as the RADIUS machines or add a route to the RADIUS machines via the management interface or through a production route.

     

    If "192.168.4.4" is not an IP address on your BIG-IP then I would look into any firewall configuration required in order for the BIG-IP to talk to the RADIUS services.
