This is a sub-selection from radius timeouts

Re: radius timeouts

At first glance it seems like an arp issue. As you have so many things behind so many things (haha) try turning on proxy-arp on the relevant interface(s) to see if it helps.

manually editing the arp may help as well.

This is torch on the core router. looking at it now, i actually think the core is forwarding on the requests.
10.40.238 is the remote radius server.

here is torch from the first pppoe server away from the core.
The problematic pppoe servers are behind this.
As you can see, there is no tx packets, only rx.

Proxy are didnt help either.

Looks as though you have some natting going on. The responses are being sent directly to 10.11.13.1 instead of 10.12.40.238.

Yes I am natting the whole 10.0.0.0 range.

Ok I see now whats happening. The radius server is seeing all the remote pppoe servers coming in as 10.11.13.1, and not their unique ips as I have configured in in the router setup in usermanager.
For instance, the radius server should see one of my pppoe servers talking to it on 10.12.40.253, but instead it sees it coming in at 10.11.13.1. As soon as I change this ip in radius, they all connect.

So how do I go about this? I am sure its just a route to add somewhere?
