OpenVPN has options where network groups can be specified. See these:
- Tunnel Settings > IPv4 Local Network/s and IPv6 Local Network/s
- Client Specific Overrides > IPv4 Local Network/s and IPv6 Local Network/s
- Client Specific Overrides > IPv4 Remote Network/s and IPv6 Remote Network/s

We have multiple sites connected to each other via OpenVPN. Each site has dozens of networks, we use aliases to handle firewall rules between them.
It would be very efficient to be able to use these aliases in the fields above also.

Here's one example of "Tunnel Settings > IPv4 Local Network/s" for one server...
172.22.222.0/24,172.22.223.0/24,172.22.221.0/24,172.22.213.0/24,172.22.212.0/24,172.22.211.0/24,172.22.210.0/24,192.168.0.0/24,192.168.119.0/24,192.168.120.0/24,172.16.15.0/24,172.16.19.0/24,172.16.22.0/24,172.16.24.0/24,172.16.27.0/24,172.16.31.0/24,192.168.20.0/24,192.168.21.0/24,192.168.23.0/24,192.168.30.0/24,172.17.15.0/24,172.17.19.0/24,172.17.124.0/22,192.168.11.0/24,172.18.19.0/24,172.18.20.0/24,172.18.15.0/24,172.18.31.0/24,10.0.4.0/24,10.0.6.0/23

Funny is, we have aliases defined for all of these nicely, nested. would be a lot better to just use the same aliases as we use for firewall rules in OpenVPN too.
