I connect to a WireGuard installed on my VPS. Then I go to a random VPN service marketing page on which I’ll discover that my DNS leaks. And which is correct because I’ve specified DNS = 1.1.1.1 in [Interface] for all the Peers.

In order to avoid DNS leakadge, do I have to a) run DNS server on the a VPS – along with WireGuard, and b) use this one and only it, instead of 1.1.1.1?

But if so, how will this possibly work?

[Peer]
PublicKey = [....;....]
PresharedKey = [......]
Endpoint = wg.my_domain123.com:51820

In order to resolve Endpoint of my VPS to begin with, other DNS server will have to be used – by IP. But there’ll be none because I’ll use a DNS on my VPS instead of 1.1.1.1. In other words, it’ll be a circular dependency.

    It’s not completely clear what you mean, but I’m guessing you’re only routing a subset of your traffic through wireguard, probably only IPv4, and there may be some IPv6 traffic that is not being routed over your wireguard connection.

    Why would you guess that?

    You can specify any IPs you want for DNS with wireguard, and if your allowed IPs include those addresses, then it should flow over your VPN.

    I do this with Pihole at home, and it blocks ads while I’m away.

    How’s that relevant to my question?

      Your question, as best as I could tell, is that you want DNS traffic to exit through your VPS node, rather than your client machine.

      I posited one reason this could be happening, and additionally, a similar setup that provably routes traffic through the VPN based on the method I described.

      Nobody in here is obligated to help you, I gave you a couple threads to pull on to resolve your question, so maybe consider accepting it graciously, rather than being obstinate.
