Might be a trivial question, however I couldn't really find anything about this topic.
I run Veeam in my homelab and have Proxmox running on an older Mainboard with integrated LAN (it's a bit of a "fun to play around with" kind of server so nothign serious ), sadly the internal port is somewhat unstable and tends to crash or behave weirdly when it's fully loaded.
Veeam B&R tends to pull a full Gigabit from that machine having a high chance of the network card crashing, I'd want to limit the speed to this machine somehow to not make this happen. I could potentially buy a new network card, however as mentioned above it's mainly a "fun server" where I'm just testing various things from free hardware I got over the years, so not really anything worth spending money on
I did try this before, but it never really worked. Might be doing something wrong tho.
Already tried the Proxmox host IP and the VM helper IP, even tried setting a speed limit on the network interface for the helper, but each time it seems to spike up to whatever it can take still and ignores all limits, then crashing the network card once and at that point B&R kind of gets confused and reports the backup job as failed...
