Question - Managing peer to peer communications about pi-hole-on-google-compute-engine-free-tier-with-full-tunnel-and-split-tunnel-wireguard-vpn-configs HOT 3 CLOSED

I noticed there is a section for this in the guide “ Enabling or Blocking communication between Wireguard Clients”. There just isn’t enough information for me to figure out how to set it up.

Not a lot of responses or activity here, which is surprising. But checking again to see if anyone can help me with this. How to I update allowed IPs in each client, if I want client A to be able to speak to client B, and vice versa. Should I be forwarding be set to 1? (sudo sysctl -p). I’d really appreciate any help or explanation on this. I only have a few clients, and just don’t understand how to make them speak to each other over vpn when outside my home network.

I figured it out from following this guide --- https://docs.pi-hole.net/guides/vpn/wireguard/internal/
**note I did not replace the postup/postdown with what was in the guide, I left it the way I had it from initial setup and so far seems to work well.

Also if wanting to enable SMB shares -
1. Firewall advanced settings > inbound rules > file and printer sharing (smb-in) > Scope > remote IP Addresses
2. Select 'these' - Make sure local network is there (eg 192.xxx.xx.0/24 or range)
3. Add wireguard single values or range (eg 10.xx.xx.0/24).
4. Note when not on the local network, will need to access with wireguard address 10.xx.xx

Also could help to make your wireguard network private on the PC, rather than public

Open Powershell as admin, then enter: Set-NetConnectionProfile -InterfaceAlias 'wg0' -NetworkCategory 'Private'
**Replace wg0 with the name of your wireguard network/interfac
