@johnpoz said in Unable setup IPv4 Tunnel Network /30:
But from that error, is seems there is some openvpn limitation for /29 being the smallest - maybe something to make sure you can use a net30 setting for sure?
This is for any tunnel subnet, f.e. /24:
.0 = network
.1 = server address
.254 = dhcp
.255 = broadcast
Those four addresses cannot be used for clients.
One can confirm this in the server log, f.e. /24:
IFCONFIG POOL IPv4: base=10.8.0.2 size=252
The deprecated /30 topology is from the past when Windows could not handle the subnet topology.
