Clients can ping server but can't ping each other

[Rexedead]

Hello! Sorry for new issue, but have no idea, what i m doing wrong.
I have a trouble with connection from client to client.
No problem with client-server and server-client.
Tried to google it, but 90% answers for linux and routing problem.

What i m tried:
✅check NAT on server side: enabled
✅Every client\server network private (checked with Get-NetConnectionProfile -NetworkCategory 'Public')
✅Edited WS4W\clients_data, WS4W\server_wg - as i have no ideas, added /24 to my clients into AllowedIPs
✅Disable firewall on clients
✅My clients has 10.5.0.0/24 as AllowedIPs in wireguard peer options

Little diagramm, how my network looks:

Sure, i have routers between server and two clients, but in my case, looks it doesnt matter (will update shema if need)

client 1 config:

[Interface]
PrivateKey = xxx
Address = 10.5.0.2
DNS = 8.8.8.8, 1.1.1.1

[Peer]
PublicKey = xxx
PresharedKey = xxx
AllowedIPs = 10.5.0.0/24
Endpoint = x.x.x.x:51820

client 2 config:

[Interface]
Address=10.5.0.7
DNS=8.8.8.8,1.1.1.1
PrivateKey=xxx

[Peer]
Endpoint=x.x.x.x:51820
AllowedIPs=10.5.0.0/24
PublicKey=xxx

Do i need edit some configs? or maybe check something else?

Hi @Rexedead, thanks for the detailed report. I can reproduce this on my end as well. This scenario works fine with WireGuard on a Linux system, so once again, we most likely have to blame the routing on Windows (and specifically the lack of control, in contrast to iptables).

As a test, I used Internet Connection Sharing instead of NAT, and that actually seemed to solve the problem for me. Could you give that a shot?

@micahmo
Tried Internet Connection Sharing and for me it's also works fine
Thanks for reply and support👍
