Routing or Firewall?

Hey everyone!

I've got a Mikrotik router (also serving as a DHCP server) with the address 10.8.145.1. The network is 10.8.145.0/24, and there's a SoftEther VPN server at 10.8.145.2.

When I connect through VPN, everything works fine (both external and internal resources), except for accessing resources at 10.8.145.2. If I move DHCP to 10.8.145.2 using dnsmasq, access to 10.8.145.2 becomes available, and everything works smoothly. However, DHCP needs to stay on the router in my case.

Appreciate any insights or advice!

I meant that clients connected to the VPN have access to the entire 10.8.145.0/24 network except for the server hosting the VPN. If I move DHCP from the router to the same server, clients gain access even to 10.8.145.2.

I've tried setting up connections both through SecureNAT and local bridge, but the situation remains unchanged.

No need for repetition. Both SE connection methods to a Linux host require interventions already described in the link.
