Hi everybody,
I recently migrated a few containers to a new proxmox infrastructure. Some of those containers were configured with a wan ip and a static MAC given by my isp, the other were on a LAN behind a pfsense.
They now are like the others configured on a LAN behind a pfsense.
Since the migration, all the containers previously configured with wan ip/static MAC need to have the MAC deleted and re-generated after reboot to get the connectivity back.

Any sugestions ?

You can change the MAC addresses at any time directly via WEB-GUI - no container reboot necessary.
 
Thanks for reply,
I know about the MAC change through GUI
My issue is that everytime I reboot those containers I loose the conectivity. The only way to have it back after reboot is to manually delete the MAC through the GUI to get a new one otherwise I get a "network unreachable"

Must be caused by something in your provider's respectively pfsense configuration. Follow the packet flow step by step using tcpdump
