Double check wireguard config?

[nktech1135]

Hello.
I’m wondering if someone could doublecheck the following wireguard config for obvious errors. wg0 works and i’m wanting to add wg1.
wg0 goes to another vyos router and wg1 goes to a linux gateway system. When commiting wg1 i got an error about the address set already being used but am not familiar enough with the protocol yet to say if it’s a problem.
Here is the config.

vyos@vyos-sh# show interfaces wireguard
wireguard wg0 {
address 10.50.50.0/24
description bks
peer bks {
allowed-ips 10.2.2.0/24
allowed-ips 192.168.0.0/16
endpoint 65.0.0.0:12345
pubkey
}
port 12345
}
wireguard wg1 {
address 10.50.50.1/24
description wl
peer wl {
allowed-ips 10.33.55.0/24
allowed-ips 192.168.0.0/16
endpoint 72.82.0.0:12345
pubkey
}
port 12345
}

Hi @nktech1135,

@nktech1135

address 10.50.50.0/24

@nktech1135

address 10.50.50.1/24

try to use different addresses from different networks. And you are able to set address 10.50.50.0/24?
which vyos version you have?

show version

on my system VyOS 1.3-rolling-202008050117 the following error will perform on a set:

vyos@vyos# set interfaces wireguard wg0 address 10.50.50.0/24

Invalid value
Value validation failed
Set failed

[edit]

because 10.50.50.0/24 is the network address, the first usable ip is .1 in this example.

Hi.
Thanks for the info. I’m running my own vyos build v1.2.5
The problem came from a misunderstanding of how addressing is supposed to work in wireguard. I updated my config to be a bit different now and all works.
setting address 10.50.50.1/24 did work though, not sure about 10.50.50.0/24, didn’t try that as the interface address.
If anyone wants to see my config i’ll be glad to post.

Thanks.
