I tried deleting the rule and it drops the traffic completely. So DNS resolution stops working and I am unsure why. It's not like default drop or anything. I can edit the rule and whatever active port 53 related rule is there works. But I want case of no such rule at all. :-)
Did you try to add -t nat -A POSTROUTING -p tcp -m tcp --dport 53 -j ACCEPT -t nat -A POSTROUTING -p udp -m udp --dport 53 -j ACCEPT after the deletion? -- Alarig
