Break trunk LACP without losing attached DHCP reservation

Hi all,

I need some help with redoing my firewall setup. It was done a while ago and I’ve made some mistakes that I’d like to correct but want to minimise the amount of work.

Here’s what I have : my firewall is a 6 ports firewall. 2 have been put in LACP and are my base LAN with all my firewall. I actually don’t need and don’t use the LACP so would prefer to break it and use them independently.

If I do so, I lose all my VLAN which would not be too bad if I didn’t lose my DHCP servers that have 10s of static ip registered that I don’t want to lose.

How should I proceed to do that with minimal effort ?

Thanks.

You could export the config via Import/Export, giving a XML file. The file can include your Interfaces, VLANs and also DHCP server. Then you adjust your config. Then you edit your XML file and re upload…

Then you adjust your config.
Then you edit your XML file and re upload it to the firewall.

Unfortunately it doesn’t seem to work. With this you have to unbound the ports first and doing so results in losing all DHCP configurations

Yes, but the config would be stored in your import/export XML file. So you would upload it again.

Yes - it was just an suggestion, how to approach that. XML Import/export supports everykind of approach.

How can an EXPORT crash something on your firewall?

You sure mean your subsequent import after editing?

I never had a "crash" when exporting from XG/XGS systems. What do you mean exactly?

The export itself doesn’t go to the end. It never finishes. The process does not finish.

not sure I understand your question tbh.

Did you try another browser? or another PC-System for the download?

That is a much more precise and helpful description as "system crashed when exporting". This sounds like "system is not usable anymore after exporting" or "system hangs", which was not the case.

So please, try to describe your observations as precise as possible. Thank you.
