Hi, new Proxmox user here.
I have two ISPs. vmbr0 connects to T-Mobile 5G (blue), and vmbr1 connects to AT&T DSL (red). I keep them sperate -- I am NOT talking about failover.
.
All VMs connect just fine to the main one (T-Mobile 5G), which is vmbr0, obviously. However, Linux VMs (Peppermint OS, or any other Debian-based OS I've tried) struggle to connect to vmbr1, which is for AT&T DSL. However, Windows 10 has zero problems. It connects immediately. Whereas for Linux VMs, it struggles on every server reboot.
The Linux VMs eventually establish a connection, after multiple retries. It takes from 5 to 20 minutes, I think.
If you must know, I have a pfSense rig that deals with my ISP connections (so I can do local networking between any device, no matter the ISP they are connected to). Any device connects perfectly fine to whichever ISP I want them connected to. It's only Linux VMs on Proxmox that have this weird problem. Not even VMWare Workdstation Player or Virtualbox have this problem.
I don't have IPv6 enabled on pfSense. I've disabled IPv6 through the Peppermint OS VM, but that doesn't help. I don't know what else to do!
