(Solved) VestaCP firewall stops all Outwards DNS lookup -even apt-get update

I'm not much versed with IPtables right now... I have setup VestaCP on a server and I made some "raw" rules there to block certain ports and allow some of them.

However after this, all outwards dns lookups stop. I can't ping google.com, can't do apt-get update, worst --- exim can't resolve any domains to send mails to.

Can you suggest what to be added to my rules tables ? will I need to it manually overide or setup the rule in my VestaCP firewall panel ??

My _iptables -L -n _shows
