I transfered my nethserver vm to another ProxMox Host, and now I am facing the following problem. To be able to get access to webinterface, I have to issue shorewall clear.
In contrary to the initial host, I now only have one interface on my nethserver (green). So after restore of the backup on the new host, I changed both nics to the only available network vmbr0. Only after issuing shorewall clear I was able connect to the webinterface of nethserver.
As there is only one network I then deleted the red network. As soon as I have done so, I cannot start shorewall anymore, so I need some help please.
To successfullly restart shorewall I added a second nic to the nethserver vm, and assign it to red network. That way shorewall does start again. But again, I only was able to connect after issuing shorewall clear.
I also tried to completely uninstall firewall/shorewall and reinstall but still the same, so I don’t know howto proceed. I surely could reinstall but I don’t want to loose the active directory server, as I did quite some configuration and dont want to re-do so I’d like to keep active directory.
