The key point here is that I can use a text editor to edit bitcoin.conf and save there OR I can input from Console and write a configuration to bitcoin.conf I did download Vim but I've never used a text editor and it seems to be a lot of work only to set the two Core configurations that bisq requires.
It's actually very easy. You can just use Notepad.exe for this. Right-click and 'open with...' Notepad.
So I want to use the console to write these configurations to the bitcoin.conf file: (a) peerbloomfilters=1 and (b) prune=0 I have searched and I cannot find the syntax
You just write the two things into the file, one per line. You can see my Bitcoin Core config
here in step 6 when it comes to the syntax / format of this file. Though I obviously don't have the
bloomfilters setting that seems to be required for Bisq.
Your other responses regarding bisq ports, I'm still working on and will get back. Roughly, I don't understand Tor and port forwarding. I decided to take the bisq documentation at face value. In my router I enabled ports for reg test, testnet, and mainnet. When I get bitcoin.conf configuration correct for bisq.network, then I'll turn on bisq's Full Node and see what happens and get back to you on that.
You don't need to open ports if using Tor, since Tor basically tunnels everything. That's one of my favourite aspects about it; no need to set port rules, no need for static IP and of course no risk of open ports in the router's firewall.
