I am trying to set-up a PPPoE connection for a FttH connection over vlan6 for a Dutch ISP RoutIT which uses the KPN network. According to the documentation, the only thing I have to enter are the username and password. The actual value do not even matter, because whatever I fill in, authentication succeeds.
After authentication, a local IP, remote IP and DNS are negotiated. I receive a local IP and DNS servers, but the remote IP is 0.0.0.0. When the local IP is added to the pppoe0 interface, the following error is visible in ppps.log:
After testing the same configuration on a Linux VM, I see something interesting:
It looks like the ppp daemon on Linux can't determine a remote IP, so it's using 10.64.64.64. This works and I can connect to the internet over the PPPoE connection.
So back to OPNSense. When I look at the Point-to-Point configuration, I can see there is a Local IP and Gateway option available for PPPoE. However, when I enter values in this field, nothing is saved.
After some research, I found out that this information is used in /usr/local/etc/inc/interfaces.inc. In this file ipcp ranges are also set. The strange thing is that local ip and gateway are only used for ppp connections, not pppoe. This looks like a mismatch between the UI and the actual script configuring mpd5?
Next i tried to override the ipcp ranges manually by editing the file mentioned before. When I set the ipcp ranges as follows, OPNsense is able to establish a PPPoE connection and everything works fine.
Does anyone has any idea how i can set these ranges instead of altering the file and losing changes whenever I upgrade OPNSense?

set ipcp ranges 0.0.0.0/0 10.64.64.64/0Does anyone has any idea how i can set these ranges instead of altering the file and losing changes whenever I upgrade OPNSense?
