I have a router with IP 192.168.1.1 subnetting 192.168.1.0/24.
On that subnet, a synology nas has an IP of 192.168.1.181 and is running a VPN server using subnet 192.168.2.0/24.
When I connect a client to that server from outside both networks, I get assigned 192.168.2.6. From that client I can ping machines on 192.168.1.0 (192.168.1.17 for example) and 192.168.1.1 & 192.168.2.1.
From machines already on 192.168.1.0, I cannot ping the VPN clients.
I would like to have two-way access across both subnets. What do I need to do?
