Hi Team,

I want to block port 80 on gateway, i have added the below command, but when i tried telnet from gateway (Telnet 127.0.0.1 80) its still showing open. when i tried to scan gateway its not detected the port 80, but from gateway its showing open.

fw ctl set int multi_portal_allow_redirect 0
touch $FWDIR/boot/modules/fwkern.conf
vi $FWDIR/boot/modules/fwkern.conf
multi_portal_allow_redirect=0

Please let me know how can i block this.

Can you create a rule that says from any source to the fw, block on port 80?
