Break trunk LACP without losing attached DHCP reservation

Nabil R1

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.

    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.

    Sure. Maybe try to apply the same to your question. 

    it is not super useful information to answer « it never crashed for me. »

    It is likely not crashing, instead it will take ages to export a fully configurated firewall with all XML files. That is the reason, you expierence this kind of "crash".

    But only exporting interfaces, VLANs and DHCP should be fine for your goals. Maybe also including NAT / firewall rules as well.

    Hello Nabil,

    this is not the polite reaction to someone trying to help you.

    I asked some questions, the purpose is collecting infos if original post did not deliver enough info to find a solution.

    Then I gave you some info from my experience, that I never watched one of many customer Sophos firewalls systems we handle, "crashing" when exporting. If you don't like that info, it's fine, it was for free. Bot don't try to educate me. It's give and take in a forum like this.

    Next step in remote troubleshooting is precise wording. So I tried to find out what you mean exactly. That's all.

    I am with LuCar Toni, I think your system maybe just slow and needs time if your export includes all objects.

    But I am out here, I don't need this.

    I do understand and I do agree. But it was a reaction to your comment that was out of line as well. A polite way is simply to ask for extra info without giving me a lesson on how I should have done better. I gave what I thought was the best description in my opinion. Appreciate that we can both learn something here
