Hi,

I have a problem with pppoe authentication using a radius server, where I have 4 radius servers but when one user tries to connect but the user is not in radius number 1 vyos does not forward requests to radius number 2.
is there a solution for this problem?

set service pppoe-server authentication mode 'radius'
set service pppoe-server authentication radius server xxxxx.tld key xxxxxx
set service pppoe-server authentication radius server xxxxx.tld key xxxxxx
set service pppoe-server authentication radius server xxxxx.tld key xxxxxx
set service pppoe-server authentication radius server xxxxx.tld key xxxxxx
set service pppoe-server authentication radius source-address 'xxx.xxx.29.113'

Thank you.

afaik, backup radius servers are only used for fallback when 1st server is down. But when 1st server responds with access-reject, fallback servers won’t be queried.
Try to configure radius server 1 , so queries for foreign domain aren’t served locally, but proxied towards server 2.
user@domain1.com → local processing
user@domain2.com → proxy to server 2
