Failover Cluster Not Working

[paul6294]

Hello,

I have 2 AS nodes set up that use RADIUS to authenticate users.

I set them up correctly, as a primary and secondary node, the failover validation passes and changes are committed successfully.

I have gathered that I only make configuration changes to the shared virtual IP Address from now on and these changes are replicated between the primary and secondary nodes - please can someone confirm to me if this is correct?

When connecting to the VPN with the primary node running, everything works well, the user is authenticated by the RADIUS server and the user connects to the VPN.

When I shut down the primary node, the VPN client is disconnected, it then tries to reconnect repeatedly with no luck. I am not sure, is the failover meant to happen automatically or is it automatic and transparent to the connected user? Is there a configuration change I am meant to make on the client side? I presumed that as the client is accessing the shared virtual IP address that this would not be necessary, the primary and secondary nodes would manage this side of the disconnect / reconnect.

Either way, if I then disconnect from the VPN client that was connected to the primary node and try to connect again (presumably to the secondary node now as the primary node is down) nothing happens. The error message is - could not establish connection with VPN server.

On the RADIUS server, I have it set up to receive requests from the primary node IP address, the secondary node IP address and the shared virtual IP address, however it just doesn't seem to work.

Any help is appreciated.

Thanks,
Paul

Same exact issue here. I cannot get it to connect to the secondary node when the primary's NIC gets disconnected.
