Since upgrading from 6.11.3->6.12.6, I have been having a host of networking issues:

1.   Cannot establish a WireGuard VPN connection (which means being in China, I cannot easily get to Github or updates via the Community App.

2.  I have a phantom double NAT showing up in my main gateway router.

3.  I use ZeroTier to access my server remotely (as well as all dockers); and could only get that back working after the upgrade by adding the zt0 listening interface

4.  I am running a Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)

5.  Diagnostics attached

 

I am looking for some advice and guidance.  Thanks in advance

 

 

My network on configuration is below:

 

 

 

Docker set up on macvlan

After enabling bridging in the Network configuration and switching to ipvlan in the Dockers, I have eliminated the phantom NIC at my gateway.  Further by disabling "Host access to custom networks" Zerotier now works.

 

I have not been able to get Wireguard working, but will post in that thread.
