First:

Just make sure you "sandwich" your text between two rows of backtick characters ` (which themselves will be invisible in the preview) looking in something like this in the editor:
```
Your Pasted Text as preformatted text with fixed width font
1
1111 (note with fixed-width fonts the numbers are right-aligned)
```
but looking like this in the rendered forum:

Your Pasted Text as preformatted text with fixed width font
   1
1111 (note with fixed-width fonts the numbers are right-aligned)

Then you need to:
A) follow the instructions here to install OpenWrt in a way that supports the modem:

Which notes:
"The integrated VRX518 DSL modem is only supported in snapshot and releases from 23.x onwards. It does not work on 22.03.x and earlier." This uses DSA so all the switch statements in your config are wrong.

So:
A) install the necessary OpenWrt snapshot
B) manually install the required firmware blobs
C) configure wan to use dsl0.7 and PPPoE

thanks!,

after all that, how does the config should look like?
should i configure wan with dsl0.7 as device and pppoe seperatly?
and what about the switch settings?

I can not really tell you, as I use my 7520 as bridged modem (running an OpenWrt snapshot from March). But I should have an older config as full router somewhere... let me search for that later...

EDIT: Mmmh, my only "as router" config predates DSA and hence is not going to be all that useful, but @elder_tinkerer already "saved the day"...
