Here is the configuration:

VPN Server
- Protocol P2TP
- Public IP x.x.x.x
- VPN Private Network 10.222.0.0/16

ER7212pc Omada Controller as VPN Client (A place)
- Protocol P2TP
- Public IP 192.168.1.100 (Behind providers NAT Router)
- VPN Private Network 10.222.48.0/24
- VPN Interface IP 10.222.0.100 (From VPN Server DHCP)
- Controller IP 10.222.48.1
- Other Device IP 10.222.48.20

Place B
- VPN Private IPs 10.222.4.0/24
- Other Device IP 10.222.4.1

HTTP and Ping from 10.222.48.20 --> 10.222.4.1 (Place A to Place B) is working, the opposite direction (10.222.4.1 -> 10.222.48.1) is not working.
I have try to create a "Policy Routing" using as interface the [vpn in] and allowing Any IP Group to Any IP Group but without success.

Does any body have success to a similar configuration?
