Hi guys, i have a serious question

I have added port 22777 to UFW to allow ssh through that port then i notice that it wouldn't work, after some time wasting, i added the same rule to iptables, then it worked, why do I have to add the same rules here and there twice? Is Ufw just a decorative app? WTF is going on? How to get rid of iptables and use only ufw? why should i allow the port twice, I need your answers please

    1. add the rule via UFW

    2. add the rule via iptables

    3. get the ufw-created rule via iptables (iptables -S | grep 22777)

    4. compare the rules to see why one of them doesn't work

    Dumb question, but is ssh listening on 22777?

    @dIREsTRAITS bruh how sleep deprived i am, i meant ip fucking tables. Fuck.

    if you want to manage with ufw, then disable iptables.

    Weird, I don't remember having this problem, and I also use an alternative Port for ssh. Iirc it just worked out of the box hmm

    Do an debugging of your ssh connection

    ssh -vvv you@yourhost

    Ffs, just do those 4 steps and see how these 2 rules added in different ways differ. That will most likely hint you the answer what might be missing in the uwf command. An if there's only 1 rule in iptables -S output, it means uwf is not functioning at all and only the rule you added through iptables was actually added

    @netikras do you think i should remove and reset everything? because anything i add to ufw is like decorations unless it's added to iptables

    @dIREsTRAITS IDK what you mean by decorations.

    For testing purposes, you could whitelist some arbitrary port, say 62770 - that would make testing and comparing the rules created by both mechanisms possible w/o any trash and the need for a reset.

    Indeed guys, the iptables had some unknown conflicts with ufw, after resetting purging everything reinstalling, now anything i add to ufw will be applied successfully.

    Thank you everyone
