communication problem between proxmox server on RPN

[sami gasmi]

hello,
I have three dedibox servers on scaleway, the ping goes through the public IP address.
After creation of RPN group, assignment of servers and creation of Linux bridge on the second network card for each server.
the communication does not pass between proxmox servers

hi,
when creating the “bridged” interface (Linux Bridge) on the second network card enp1s0f1 in DHCP mode, it works. the dynamic IP address assigned is that of the private IP address of the RPN group. valid communication between servers.
If I fix the (static) IP address, there is no more communication, which blocks the creation of my cluster. that's my problem.
