My setup is several VM's, with a local subnet (192.168.10.0/24)
Host machine is 192.168.10.1 (br1) (or 10.30.0.7 interface with inet) it runs a DHCP server to assign my VM's their IP's.
I don't want to bridge the connection like normal with brctl addif but instead I want the VM's to be able to connect to the internet sharing the host's IP (specifically 10.30.0.1 or interface wg0 (wireguard))
How can I do this with iptables?
