Upgrading router, Wireguard not working

I need to do in-place upgrade from 750GL to Hap AC2. If I export and import (both are on ROS 7.11.3) I run out of space on the new router, so I decided to set it up from 0.

I probably don’t see something obvious since client can’t access the local LAN, nor there is internet flowing. Client seems to connect, but can’t ping anything on the remote LAN (General Failure).

router:

This is the client config:

[Interface]
PrivateKey = wKbcpQzvfbfB9XjgO9lpt6WzQ+H3tdx2dllb6ZeAvEc=
Address = 10.10.5.2/32
DNS = 8.8.8.8

[Peer]
PublicKey = GlSdxtCl0Cgf96KS3cFJ0Q1iXXSX1vi640ZiwVrD1F8=
AllowedIPs = 0.0.0.0/0
Endpoint = Public IP:13231
PersistentKeepalive = 10

Perhaps the following on the server

/interface detect-internet
set detect-interface-list=none
/interface list member
add comment=defconf interface=“WG VPN” list=LAN

You may want to eventually restrict it a bit more than giving it full LAN access, but in the short term…

Client:
Only if the client is also a Mikrotik, perhaps make its
“WG VPN” a member of the WAN interface list.

The keys are useless in regards to the problem, but very usefull for unethical stuff.

Clients are Windows/Android.

Adding interface seems to allow internet only, but still can’t access LAN. I will try again later.

Router will be blanked once I find what the problem is :slight_smile:

Update on this, for some reason 0.0.0.0/0 on the client side was not working. 10.0.0.0/8 works fine. Sigh… I am just happy it works.
