Hi,
I have set up my GL-iNet router with dual WAN connection, and create fwmark the traffic to with following iptables commands, and related ip rule and route tables
iptables -t mangle -A PREROUTING -i br-lan -m geoip ! --destination-country DE -j MARK --set-mark 0x2
Traffic from connected clients are successfully fwmark(ed) and correctly routed. However, the traffic originated from router itself could not be fwmark(ed), and only go to the primary link.
How to FWMARK router local original traffic?
Thanks Joseph
