Cannot reach docker container over macvlan

[fratrue]

Hi!

 

I have set up a Pi-hole docker with a macvlan custom network. The ultimate goal is to reach the Pi-hole instance both from my local LAN and from Wireguard clients connected to the unRAID server.

 

Network details:

unRAID IP: 192.168.0.3

Pi-hole IP: 192.168.0.129

Gateway: 192.168.0.1

 

The issue is that, while macvlan appears to work and I can reach the Pi-hole instance from my LAN, I can't access it from unRAID or any Wireguard clients connected to it.

 

root@unRAID:/mnt# ping 192.168.0.129
PING 192.168.0.129 (192.168.0.129) 56(84) bytes of data.
From 192.168.0.3 icmp_seq=1 Destination Host Unreachable
From 192.168.0.3 icmp_seq=2 Destination Host Unreachable
From 192.168.0.3 icmp_seq=3 Destination Host Unreachable

 

I have enabled Host access to custom networks under Docker settings and even turned it on and off a few times but no differences.

 

Thanks!

Looks like this was due to Host access to custom networks not working immediately with user-defined custom networks. I had to enable a "br0" custom network in the GUI and then the server started to reach the containers with custom IP.

 

 

However, now I have the issue that Wireguard clients can no longer reach LAN IPs. I have set NAT to Off and added the requested static route in my router but unfortunately if doesn't work.

 

 

Any tips? Is this kind of setup supposed to work?

 

Thanks!
