iptables -F
iptables -t mangle -N internet
iptables -t mangle -A PREROUTING -j internet
iptables -t mangle -A internet -j MARK --set-mark 99


the iptables entry below blocks all traffic but captive portal does not popup



iptables -t nat -A PREROUTING -m mark --mark 99 -p all -j DNAT --to-destination 10.10.10.1


if ommitted captive portal does popup but some online games like mobile legends are able to pass. im guessing that if i add that -p all im also blocking the ckecking of the portal. I just dont know what it is.



iptables -t nat -A PREROUTING -m mark --mark 99 -p tcp --dport 443 -j DNAT --to-destination 10.10.10.1:443
iptables -t nat -A PREROUTING -m mark --mark 99 -p tcp --dport 80 -j DNAT --to-destination 10.10.10.1:80

iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
