Update: latest rolling has a bit different syntax. I think users just not migrated properly on update. After adding
set service ipoe-server authentication interface eth1.50 mac 00:50:79:66:68:03 set service ipoe-server authentication interface eth1.51 mac 00:50:79:66:68:04
I see that chap-secrets file generated properly and users getsIPs
