Firewall Rule to allow all outbound traffic help

    • Hi all


    I am trying to set up my firewall on my OMV VM. I have set up a few inbound rules that all work fine. I cant seem to get a blanket out bound rule set up tho. I am trying to set a alow all rule on out bound.


    Please see below for my rules.



    Does this look correct ?


  • It should work if OUTPUT Chain is ACCEPT.
    Optionally, you can -A OUTPUT -j ACCEPT but you already have it.
    You can optionally add
    -A OUTPUT -m conntrack --ctstate RELATED, ESTABLISHED -j ACCEPT
    -A OUTPUT -o lo -j ACCEPT


    But what exactly is the problem? Outgoing traffic is blocked? Maybe vm is....
