Wiki issue: inter containers networking and firewall rules

What's the issue?
Please add a note regarding the FIREWALL_OUTBOUND_SUBNETS parameter to the wiki page. Currently, it's missing, and this can lead to connectivity issues between two containers. For example, 172.22.0.22/16 is unreachable from a gluetun container if FIREWALL_OUTBOUND_SUBNETS is not set in the gluetun container's environment options.
