Setting host-uniq for PPPoE
-
My ISP uses the host-uniq part of the PPPoE PADI packet to authenticate the system before any communication. How can I set this value in PfSense?

thank you for creating a feature request!
Is there someway to do this directly through the shell for now? Do you have any insight on which files I should edit using the shell?

Hey!
Unfortunately I can't connect to the internet from my PfSense machine yet. How can I manually make these changes? From what I read, applying the patch requires internet access. -
@parithosh you can copy-paste it:

So i copied over the snippet, applied it with
patchonto the files/etc/inc/interfaces.incand/usr/local/www/interfaces.php. This created thehost-uniqfield in the WAN page under PPPoE as shown in the image. I entered the same value as your example.
However, when I run tcpdump on the VLAN7 interface (needed by the ISP), then I still get random values under
host-uniqand none of them being the value I set.
Is there someway I can check if it has been applied correctly? (I did hit save and Apply changes already).

@parithosh PR updated, now it works correctly and I can see Host-Uniq value in packet capture:

Thank you so much! That works exactly as expected. I seem to still not receive any response to my PADI packet, but i am clarifying with my ISP if something more is required.
-
I need the VLAN7 interface (needed by the ISP), too. How do I convert it into hex?
-
The host-uniq ID has nothing to do with the VLAN. If your ISP needs a VLAN create the that and then use the VLAN interface as the parent for the PPPoE config.
