Second internal interface on the same subnet as clients

Post by vicenac » Wed Jul 10, 2019 10:58 pm

Can I add a second interface to the access server that is on the same subnet as the VPN clients?

In detail:
The OpenVPN has an interface in my DMZ for clients to connect to.
I'd like to add a second interface to the OpenVPN server on a new subnet in our internal network (not DMZ). This new subnet will be the same as the client subnet.
The switch/router will have, for example, 10.10.1.1/24 (so it can route to other subnets), the OpenVPN server will have an interface on this subnet, 10.10.1.2/24 and clients will be assigned 10.10.1.20-10.10.1.200 (for example).
This would simplify routing, sine the client subnet would be "known" to the internal network. The clients and the switch/router will share the L2 network.

Is this setup supported?
