Hi,

 

this is a quick how to with smart phone app "OMADA" and "Wireguard".

 

In my case, the gateway ER605 is connected to my FritzBox and i have a DS-Lite (IPv4 / IPv6) internet connection.

I had to create at first a UDP portforwarding in the FirtzBox for my Device ER605.

 

In Step 5

you can type any IP Adress what you want also from an existing vlan network where you have already any acl rules.

You can see under in section Insights - Routing Table the system creates a new different interface which you not see under Networks

 

In Step 6

you have to copy the generated public key from your interface of ER605

and paste it later in the WireGuard App for the peer connection

 

In Step 10 / 21

when you choose a unique IP address out of you existing vlan/network and you have any acl rules for this network, it also take affect this WG VPN connection

 

You can also type a new network and create after this a acl rule on switch to restrict the access to other networks.

 

In Step 11

you can type here also only the gateway's DNS Server IP or you can type here 8.8.8.8,1.1.1.1 ....

 

you can use the Server-A for more as one User.

In the WireGuard App the peer public key is the same (Server-A)

only the new generated public key from the user in the app is different

and you have to use it in the OMADA App for the new user.

 

I don't know how much user you can use for one interface (Server) ?
