Why is traffic not being routed?

Question

VPN

Good evening Guru!!!
The network diagram is simple.
There is a router-receiver (there is no provider of satellite Internet access to it), 1 port, gives out the
IP range 10.192.1.1-10.192.1.200
This cable is plugged into the Mikrotik, and the DHCP Client is configured (We get IP 10.192.1.58)
On the Mikrotik, except for the van port , 2 more ports are used .
Eth 1 - WAN (10.192.1.58)
Eth2 - Bridge_LAN1 (10.48.0.1-10.48.0.85)
Eth2 - Bridge_LAN2 (192.168.0.1-192.168.0.45)
The VPN L2TP client was also raised on Mikrotik.
On the VPN server we see the network 192.168.0.1-192.168.0.45 (but 1 IP address is enough for us)
We want to put the second network directly on the Internet.
We write in NAT

chain=srcnat action=masquerade out-interface=VPN log=no log-prefix=""
chain=srcnat action=masquerade out-interface=ether1_WAN log=no log-prefix=""

In Route
One route was added by hand. to the local area network of the VPN server

4 AS 192.168.4.0/24 10.80.0.25 10.80.0.20 1

In principle, everything, nothing else was set up)
Now, the question. How to launch one Eth2 network - Bridge_LAN1 (10.48.0.1-10.48.0.85) via VPN (so that the VPN server networks and the VPN client network are friends)
And the second Eth2 network - Bridge_LAN1 (10.48.0.1-10.48.0.85) - directly to the Internet.
And so that the nat of the router-receiver does not interfere with us))
Thank you

Only in your case is the subnet marked
