iptable rules for my 1200ac openwrt router to allow remote play on Chiaki

ps4_remote_play_wan.sh

IPADDR='192.168.1.224'
SOURCE='192.168.1.0/24'

for PORT in 80 443 9295; do
    iptables -I FORWARD -p tcp ! --source $SOURCE -d $IPADDR --dport $PORT -j ACCEPT ;
    iptables -I PREROUTING -t nat -p tcp ! --source $SOURCE --dport $PORT -j DNAT --to $IPADDR:$PORT ;
done

for PORT in 9296 9297; do
    iptables -I FORWARD -p udp ! --source $SOURCE -d $IPADDR --dport $PORT -j ACCEPT ;
    iptables -I PREROUTING -t nat -p udp ! --source $SOURCE --dport $PORT -j DNAT --to $IPADDR:$PORT ;
done

The above iptables rules will forward all of the necessary ports to use Chiaki unless you are on the LAN! If this is not done then no one on the LAN will be able to use the internet. You don't need to use Chiaki while you are on the LAN anyway. In case you do for odd reason though then you can omit the following portion of the iptables rules '! --source $SOURCE'. This will forward everyone's port requests whether it be over the LAN or WAN.

Example NATing for all(! Source IP omitted)

IPADDR='192.168.1.224'
SOURCE='192.168.1.0/24'

for PORT in 80 443 9295; do
    iptables -I FORWARD -p tcp -d $IPADDR --dport $PORT -j ACCEPT ;
    iptables -I PREROUTING -t nat -p tcp --dport $PORT -j DNAT --to $IPADDR:$PORT ;
done

for PORT in 9296 9297; do
    iptables -I FORWARD -p udp -d $IPADDR --dport $PORT -j ACCEPT ;
    iptables -I PREROUTING -t nat -p udp --dport $PORT -j DNAT --to $IPADDR:$PORT ;
done
