Wireguard no longer connects after upgrade from FW revision 20240519 to 20240612 about xzg HOT 18 CLOSED

Comparing to the previous config you just give more options when initializing:

yep, cause of using another version of WireGuard library

I think is was 20240504. But I will do new tests in a few days and try to find out the problem.

from xzg.

Ok, I'll look in a few days, thanks.

It works for me in version 20240612:

"vpn-config": {
"wgEnable": true,
"wgLocalIP": “10.100.0.4”, //Peer address
"wgLocalSubnet": "255.255.255.0", //Peer netmask
"wgLocalPort": 33333,
"wgLocalGateway": "0.0.0.0",
"wgLocalPrivKey": “xxxx+xxxxx=",
"wgEndAddr": “xxxxx”, //Server address
"wgEndPubKey": “xxxxx”,
"wgEndPort": 51820,
"wgAllowedIP": “0.0.0.0”, //What IPs are allowed to connect to this peer
"wgAllowedMask": "0.0.0.0", //Subnet for ^
"wgMakeDefault": true,
"wgPreSharedKey": "",
},

from xzg.

wgEndAddr is IP or hostname ? Could you try using IP ?

from xzg.

It is an IP.

It looks like it never worked after upgrading to XZG.

Looking at this function: https://github.com/xyzroe/XZG/blob/main/src/etc.cpp#L828

The configuration should be OK.

@xyzroe
In this example: https://github.com/ciniml/WireGuard-ESP32-Arduino/blob/main/examples/uptime_post/uptime_post.ino
there are only 5 variables for wg.Begin. Maybe the extra config is creating issues?

no you're wrong. I made some tests and get stable working connection

from xzg.

The test you mention, which version did you test?

from xzg.

Need to check when additional config options added. That way we can found tested version

Hi,
Maybe I am configuring it wrongly.

In the previous version of the library, there wasn't a variable called Local Gateway. I managed to connect (once, somehow) when this was set to nothing, but there was no comunnication via the wireguard interface.

What should I enter into this field? The gateway of the local network the device is connected to?

I tried to find the variable meaning in repo https://github.com/Tinkerforge/WireGuard-ESP32-Arduino, but I just can see the basic vars which were used in the UZG.

Edit: Found the header file with some comments about variables:
https://github.com/Tinkerforge/WireGuard-ESP32-Arduino/blob/main/src/WireGuard-ESP32.h

vpnCfg.wgLocalGateway translates to:
// Gateway of the WireGuard network
const IPAddress& Gateway,

from xzg.

Have you tried with default Local gateway = 0.0.0.0 ?

from xzg.

Yes. "Worked" once. Handshake with my router was completed, but non of the communucation worked. Ping did not work.

Now I am trying to manually enter the gateway from the wifi network that the UZG is connected to.

from xzg.

BTW. There are two more commits in the library after linked commit [WireGuard @ 58de5da](https://github.com/Tinkerforge/WireGuard-ESP32-Arduino/tree/58de5da725bf11720439306496d8962dcb26af61)

https://github.com/Tinkerforge/WireGuard-ESP32-Arduino/activity

I am honestly not that much fluent to be able to asses if they would make the difference...

from xzg.

Thanks 👍

I just opened a pull request #86 with a quick VPN runthrough :)
