So doing a POC, with Nginx load balancer and freeradius docker. When the request packet is sent to the freeradius container from the proxy, the reply is received by the proxy and all is well.
So the containers are working as expected 100%.
However when the proxy sends the request to the freeradius container through the Nginx load balancer, the freeradius gets the access request packet, but then the access accept packet replies back with the containers IP.
So the proxy sends another request and the freeradius container replies back with the containers IP.
Proxy sends the request to radius:
Sent Accounting-Request Id 90 from xxx.xxx.xxx.xxx:55039 to xxx.xxx.xxx.xxx:1813 length 467
Radius replies
Sent Accounting-Response Id 1 from 172.18.0.5:1813 to xxx.xxx.xxx.xxx:37741 length 25
Proxy never gets the response:
(29) No proxy response, giving up on request and marking it done
(29) ERROR: Failing proxied request for user "vlan1106/lab-1-1070-1106", due to lack of any response from home server 154.119.32.156 port 1813
The Nginx load balancers are configured with transparent, as I need to know the source IP from where the request is made. When not in transparent then it works as the reply packet has the correct IP in the header.
Is there anything that I'm missing here? Been head butting this problem since Saturday.
