Attached the patch i made for the version 1.12.0-202-g28fe4de. It will use Calling Number/Called Number as RADIUS Calling-Station-Id/Called-Station-Id in case they are present in L2TP ICRQ, otherwise old beahvior is used (LAC/LNS IP addresses).

just to discuss the possibilities.
I see Calling-Number/Called-Numer AVPs can be taken from attr->val.octets doing something within l2tp_recv_ICRQ procedure:

-DKDIR=/usr/src/linux-headers-`uname -r` \
-DCMAKE_INSTALL_PREFIX=/usr \

Hi.
Is there any recommendations on compiling and embedding newly compiled version of accel-ppp to vyos 1.4 ?
I mean how to install newly built package into VyOS 1.4.
The deb built on Debian11 and installed with dpkg on VyOS does not start for some reason with no output.

Is there any chance to fix that ?
