Proxmox Bridged on Hetzner routing - guest can access network, but can't connect to other VMs

[asandor]

There's a two node PVE solution, where the second, newer install has some routing issues: the VMs on the node can access public internet, can download packages, I can SSH to them from local machine, etc., but when trying to connect to them from the VMs of the other node, they're unavailable: ping shows Destination Host Unreachable SSH from VMs on different subnet shows No route to host. I checked routing setup of the new PVE node and it shows an incorrect address, that I'm not sure where it's coming from:

Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 10.0.0.1 0.0.0.0 UG 0 0 0 enp35s0 10.0.0.248 0.0.0.0 10.0.0.3 U 0 0 0 vmbr0

/etc/network/interfaces

auto lo iface lo inet loopback iface lo inet6 loopback auto enp35s0 iface enp35s0 inet static address server address gateway 10.0.0.1 iface enp35s0 inet6 static address xxxxxxx/64 gateway xxxx auto vmbr0 iface vmbr0 inet static address 10.0.0.249 netmask 10.0.0.3 bridge-ports none bridge-stp off bridge-fd 0

I flushed the route, but had no effect. I tried to remove the route with "ip route del 10.0.0.248 via 0.0.0.0" and the response was "RTNETLINK answers: No such process"


10.0.0.1 proxmox gateway
10.0.0.2 proxmox public server gateway
10.0.0.249 correct gateway
10.0.0.248 is an incorrect address
10.0.0.3 netmask

Any suggestions?

10.0.0.3 netmask

The above is not a netmask.

The above is not a netmask.

neither of them are the actual addresses
