To elaborate on the situation for three GL.inet routers Site-2-Site:
wireguard server firmware >=4.5 is required
Topology：
Steps：
- wgserver: add two profiles on admin panel of wgserver, and export conf file for wgclient’s usage.
-
wgclient: import conf file, connect to wgserver, and turn on ”Allow Remote Access LAN”
-
wgserver: enable ”Client to Client“
Now：
PC 192.168.172.2 can access 10.0.0.3
PC 192.168.173.2 can access 10.0.0.2
- wgserver: add custom routes
Now：
PC 192.168.172.2 and 192.168.172.3 can communicate, ie, site-to-site network is done.
Add more wgclient to join more sites, just as 10.0.0.2 and 10.0.0.3.
