WireGuard quickstart

I'm having issues with getting the handshake to successfully occur.

 

I have WG setup on my Unraid server using the public IP. (I will use DDNS later, but I'm trying to reduce variables to solve this problem.)

I am running an EdgeRouter and setup a port forward to my unraid server.  I've ensured bridging is enabled on eth0.

 

I have configured a peer as "Remote Access to LAN" and tested this config using the QR code method on my iPhone.  I can't get my iPhone to handshake with Unraid.  I have Local server uses NAT set to Yes for now.  Will setup the static route later once I can get the basic stuff working.

 

Here is an screenshot of my configuration:

 

I read through this whole thread and saw some people had the same issue as me and tried the different solutions that worked for them, but none worked for me.  Any thoughts on what I can do to identify the issue? Thanks!

At a guess I would say check your port forwarding is correct as I have exactly the same setting as your screenshot and works fine.

I had the same issue using the QR code on Android. I downloaded the config instead and imported it directly in the app. That solved it for me. Now it is working as expected.

 

As a side note. I had to change the filename of the conf file. Otherwise the app told me it can't import it8fda3430e07cc8c4462325db3acc9472.jpg&key=7c697c0466b12698ab9cb1dff142fbeddc3ceb7ec1348506599c7d0ada47f866

 

The shown QR code is just an example without function for reference.

I'm still getting weirdness connecting to my dockers.  From certain external IPs they can't connect at all to any of my docker services unless i disable the vpn connection.  Other external Ips are working fine so i am not sure how this would get messed up?

Do you know what IP subnet the dockers and problem sites are on?    I have encountered routing issues where the remote subnet and the LAN end are on the same subnet.   Not sure if this is an inherent problem or I just do not know how to set up things correctly, but just in case I have moved my home LAN to not be on 192.168.0.x or 192.168.1.x ranges as these are commonly used elsewhere.

The wireguard subnet is 10.9.0.x

Local Lan is 192.168.254.x

Remote IP example that doesn't work is 69.17.172.210

Remote IP example that does work is 140.238.153.159

Docker subnet 172.17.0.1?

What LAN addresses are you assigned on those remote WAN's?

Those IPs are not connecting to wireguard.  They are only connecting to the nginx docker via my external IP.  The one is a 192.168.0.x network the other i dont know since its not mine but i doubt their internal network address would be relevant when they connect via my external public IP.  The only reference to wireguard in this is that when its enabled they cant hit my dockers, when its disabled they can hit them fine.  Its like a routing issue where the reply to the request is going out over the VPN instead of directly back, if that makes sense.

That is the case for all VPN variants

unraid is the peer as I mentioned before.

 

The remote VPN server has:

ens3: 10.0.0.5

lo: 127.0.0.1

tun0: 10.8.0.1

wg0: 10.9.0.1

 

Local unraid uses:

br0: 192.168.254.3

docker0: 172.17.0.1

eth0: some ipv6 address?

lo: 127.0.0.1

bunch of vethxxxx: ipv6

wg0 10.9.0.6

 

No overlaps except the wg interfaces on both which is proper.

 

Note, I am not using wireguard to connect from outside in.  I am using it to route unraid traffic out over vpn.

Just to be sure. You want to connect your unraid server to a VPN server somewhere in the world?

And this is some kind of VPN provider and no private person?

It is a private VPN.  I have 4 different VPS servers that I use for VPN.  All have the same issue if I use a different one.  Then again, they are all setup more or less the same but no other clients connecting to them have issues.

If you connect your pc via VPN with your VPS it is working and with the unraid (same network) it doesn't?

All remote peers need a correct setting for "AllowedIPs" to reach the Unraid server and/or containers over the tunnel.

 

There are no remote peers accessing unraid or dockers via vpn.

 

Remote peers are accessing Dockers directly via external IP/port.

So basically if I have a VPN on unraid I can't use any Dockers from outside my network?  Any way to correct the routing?

A VPN connection in essence means your system is only reachable over its VPN connection. Any other path is considered 'route leaking' and usually not what you want (security breach).

But then why do some remote ips work still but others not?

You mean certain containers are still reachable?

This is expected when these containers run on a custom (macvlan) network.

Hi, got this setup in a matter of minutes following the guide posted and connecting to my server works great!!

 

Problem is that i cant access anything else on the web from the peer (iphone 11 pro on ios 13.)

 

I tried both "Remote tunneled access" and "Remote access to Lan" access types with the same issue on both.

 

Any ideas?

 

Thx
