OpenVPN TAP connection between two ASUS routers

[Radek1982]

Hi All,

Hopefully I can get some suggestion how to solve some issues I'm experiencing while trying to establish OpenVPN connection in TAP mode between two locations.
In location A (Ireland) I've Asus RT-AC56U router running Merlin firmware 380.65_2.
In location B (Poland) I've Asus RT-AC51U router running stock firmware 3.0.0.4.380_3625-geb2b179.

Location A is running OpenVPN server (see my configuration below):

Location B is running OpenVPN client (see confirmation that this connection is successful):

Location A has LAN IP: 192.168.0.1 & DHCP pool 192.168.0.2 - 192.168.0.99
Location B has LAN IP: 192.168.1.1 & DHCP pool 192.168.1.2 - 192.168.1.254

My understanding of TAP mode was that when successfully connected than any device connected to any of two routers will be on one virtual LAN. Unfortunately first of all when checking IP on device connected through router running client OpenVPN on location B, I'm still getting Polish IP (not Irish as expected).
Secondly I can't reach out to any devices connected via router on the other end of my VPN connection.

I would really appreciate if any of you could give me some suggestions what should I change in my configuration to make it work.
