How to set up two-way communication between kerio VPN server and l2tp client?

Question

VPN

On the kerio control server, there is a server with VPN clients connected to it in the kerio VPN / IPSec interfaces section (client network 10.1.60.0/24). I'm trying to connect Asus rt-ac66u (firmware tomato VPN) as an l2tp client to the server using 3G Internet (l2tp connection is selected on the WAN interface). The connection is established, the internal IP is assigned: 10.1.60.228.
From the hosts connected to asus and asus itself, the kerio 10.1.50.1 server and the 10.1.50.0/24 subnet behind the server itself are pinged.
But neither from a computer connected to kerio nor from kerio can ping either the l2tp client or the subnet behind the client.
Windows kerio VPN clients connected to this server ping in both directions. The rules are the same for them!
Question: How to correctly register routes so that you can reach the l2tp asus client and the subnet behind it?

Answer 1

routes are registered? it is not enough to set up a service in kerio, you also need to prescribe rules in the firewall and routes
