hi but i never configured the firewall on the mailcow system……..
is there an option to reset the firewall?
It has nothing to do with mailcow or docker. Configure your firewall on your host the right way. I’m pretty sure docker and mailcow will then work.
ok can you help me with this? please? i dont know where to start. what i did was yust instal mailcow and configure domain etc etc…….
Ckruijntjens Warning: iptables-legacy tables present, use iptables-legacy to see them
you do have a warning… check google. You might want to purge iptables. You might have problems with the mixture of the 2 firewalls: iptable and nftable.
KillVirus do i need both? iptables and nfstables
KillVirus You might want to purge iptables
Ckruijntjens do i need both? iptables and nftables
[ ] I read what you wrote.
For me it works to purge (remove) iptable and working only with nftable. You will find some instructions to setup a firewall on your system in the web.
KillVirus hmmm if i remove iptable docker wont start anymore….
KillVirus what os are you using?
lol my system is working 😉 debian
Do you have nftable installed?
yes it is installed.
KillVirus i cant remove iptables. docker.io will also be removed…..
watch log files or error messages when start of docker fails.
KillVirus its because docker.io is uninstalled.
when i reinstall docker.io iptables is installed by default.
my setup is now.
geust kvm debain 11. In this geust i installed docker. and docker (mailcow)
i dont understand why it is not working out of the box…
Ckruijntjens i dont understand why it is not working out of the box…
On debian 10 it began switching:
I had problems with that mixture on debian 10 too. For me it works for removing all to do with iptable like I wrote.
On the link above you can also see how it should look like in standard with: “Chain INPUT”
And again you might want to find a good guide to setup your firewall.
something else is going on or wrong however i can not find it. maybe i will install a empty vm i reinstall all to se if it works.
what debian version are you using?
KillVirus when i dont run anythin else on this machine i do not have to create a manual firewall rules correct?
KillVirus when you remove all iptables packages. how did you reinstall docker then?
because it will uninstall docker on my system?
please look for a “how to set up nftable firewall on debian”.. Or read my link above for learning in 10min 😉
