LACP from ISP to Active/Passive

Where exactly would you like to get help? Have you read the documentation from Sophos and get stuck somewhere?

LACP is not usable in this scenario.

Hello apijnappels ,

Thank you for reaching out to the community, please refer the useful KBAs below:
1.) Configure LAG in HA.
2.) Additionally,  Configure access layer switches for XGS HA.

Vivek Jagad  thanks for your replay, but I did not find solution.

I want configure redundant LAN link  for each switches from two firewalls, I haven't found any solution for that, kindly help me for this.

This is our network architecture for reference.

Lakkappa Aras  you cannot make this scenario work as you have it drawn. You would need managed layer 3 switches that form a cluster or virtual chassis to make this work. The XG's would also need to be in HA as well. You would then link the virtual chassis switches to the XG's using LAG interfaces.
