problem with AVM fritzbox wiregurad config [Bug]: about raspap-webgui

[billz]

If your wg config is of a nonstandard format, the parser may fail to handle it. Please share your wg0.conf (with keys removed) similar to this #1430 (reply in thread)

Previously fixed with #1432

hi,

here it is, ist direct from the FritzBox and works on a Win11 PC with Wireguard (if it helps)

[Interface]
PrivateKey = [PrivateKey]
Address = 192.168.178.203/24
DNS = 192.168.178.1
DNS = fritz.box

[Peer]
PublicKey = [PublicKey]
PresharedKey = [PresharedKey]
AllowedIPs = 192.168.178.0/24,0.0.0.0/0
Endpoint = [Endpoint]
PersistentKeepalive = 25

bz edit (formatting)

Thanks. RaspAP expects a single DNS value in the client config, see this as an example. Multiple values are unusual, hence the error. In the short term, removing the second DNS value should allow you to start the wg service (I'm guessing the FQDN resolves to your router's IPv4 address).

Hi again,
thanks 4 support! But its still nor running

ive changed the .conf like the linked example:

[Interface]
PrivateKey = [PrivateKey]
Address = 192.168.178.203/24
DNS = 192.168.178.1

[Peer]
PublicKey = [PublicKey]
PresharedKey = [PresharedKey]
Endpoint = [Endpoint]
AllowedIPs = 192.168.178.0/24,0.0.0.0/0

The first line in the service output is the clue:

wg-quick: `/etc/wireguard/wg0.conf' does not exist

You can either rename this file, or edit it on another device and (re)upload it via RaspAP. This will ensure that the file is saved in the correct location.

Using 3 backticks to format code blocks ``` makes output easier to read 😉

hi

ok, i just clicked on the Code Button...

next try by renamed it t wg0.conf resolved:
