Mikrotik openvpn server and network behind clients?

Question

openvpn

There is a Mikrotik, an openvpn server is deployed on it. Mikrotik ip: 192.168.15.10, vpn network 192.168.150.1 Mikrotik
routes

8 ADS 192.168.22.0/24 1
11 ADC 192.168.150.250/32 192.168.150.1 0

An openvpn client router on dd-wrt is connected to it, network 192.168.22.1, ip vpn 192.168.150.250
Routes on dd-wrt

Route
192.168.15.0 192.168.150.1 255.255.255.0 UG 0 0 0 TAP1
192.168.22.0 * 255.255.255.0 U 0 0 0 BR0
192.168.150.0 192.168.150.1 255.255.25.0 UG 0 0 0 TAP1
192.168.150.0 * 255.255.25.0 U 0 0 0 tap1

iptables client vpn config

As a result, from the Mikrotik network, I see only the IP address of the dd-wrt 22.1 router, I do not see the network behind it. Tell me what to do

Answer 1

Always follow a simple rule:
1. There must be routes through VPN points
on both ends 2. there must be rules on the firewall on both ends allowing passage from another network.
If something "doesn't work" for you, draw a general picture of the connection, draw the packet movement (traceroute), see where the break is, think.
In your case, if Mikrotik has a route to the vpn network (by the way, you seem to have registered it incorrectly, the network address is abc0/24, see what interface ddwrt looks at in vpn, through it there should be a route to the ddwrt network.
