Docker EE & Nagios

Hi All

I have docker EE installed & it has check_mk agent install for basic OS monitoring

As soon as Docker EE is installed the check_mk checks failing as i can not hit port 6556

What is bets way to add this port in firewall as i know firewall is managed by docker

Also we use Ubuntu 16.04 & this service also need xinetd

Thanks

i tried iptables -I DOCKER-USER -p tcp --dport 6556 -m conntrack -cstate NEW… -i ACEEPT

but no luck
