Hello,
On RUT955 with firmware RUT9_R_00.07.02.3, custom firewall rules doesn't work only after reboot and loses connectivity with the Site PLC. However the same custom firewall rules works when the firewall rules are resaved after every reboot. The firewall rule is as follows :
iptables -A INPUT -p tcp --dport 1883 -s 192.168.x.x-j ACCEPT
iptables -A INPUT -p tcp --dport 1883 -s 10.x.x.x -j ACCEPT
iptables -A INPUT -p tcp --dport 1883 -j DROP
Could someone point out the issue and applicable fix?
