Sorry Arthur, that's nftables syntax.
For iptables, you would want:
`sudo iptables -I FORWARD -i "vif*" -o "vif*" -j ACCEPT`
because you want that rule to PRECEDE the existing one that blocks
traffic.

For nftables I would rewrite the FORWARD chain and atomically rewrite it at
sys-firewall startup.
You can do this by using the scripts in /rw/config.
