HA-Proxy, how to set correctly a shared fronted with Offloading and TCP

[BelluX]

Hi,

i'm new to haproxy

i have two local server, one have an internal certficate and another one will sign/renew with pfsense. i need to create a shared frontend to work with 443 with these two server, i followed and search some guide to set up haproxy correctly but i found nothing about a shared fronted.

I endend up setting all like you see in the attachment and it works because i can reach endpoint without problem and all have the certificate seen correctly when i try to enter from outside.

The problem is the warning you see, i don't know how to set up properly a shared frontend, if i shutdwon the two that are working for offloading and tcp everything stop working.

Which guide i can follow or what yuo suggest to adjust for the shared frontend to work properly.

Thank you.
