Newbie Port Filter Question on 4.10stable

[Evren Yurtesen]

Hi,

I think if your firewall is normally working fine. You can use

#sh /etc/rc.firewall &

(notice the & for putting it background)

Because if you have last default rule to deny everything, the 
rc.firewall script first flushes every rule and if you are connected via 
ssh etc. you would get disconnected immediately and execution of 
rc.firewall stops, so it is not able to load the new rules. If it is on 
background then it will continue working till the end and put the new 
rules into action.

Please let me know if you find any better solution :) I always use
#sh rc.firewall &
but there is always a better way :p
