My gateway is 192.168.1.1 and I reserved 192.168.1.10 for my Proxmox server. I can access the Proxmox web UI through 192.168.1.10:8006 and all of my VMs work fine, but whenever I try to ping any address (local or external) from the shell it either times out or does nothing. I'm unable to update my proxmox server because of this.

A few months ago I changed routers to an OPNsense router, and the previous IP address was 192.168.4.141. Not sure if that's relevant but couldn't hurt to mention.

Any ideas on what I can try? Thanks
 
please post the network config (/etc/network/interfaces) of your PVE system..
 
Here's the contents of the interfaces file:

auto lo
iface lo inet loopback

iface enp0s25 inet manual

auto ens1f0
iface ens1f0 inet manual

auto ens1f1
iface ens1f1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.10/24
gateway 192.168.1.1
bridge-ports enp0s25
bridge-stp off
bridge-fd 0

auto vmbr1
iface vmbr1 inet manual
bridge-ports ens1f0
bridge-stp off
bridge-fd 0

auto vmbr2
iface vmbr2 inet manual
bridge-ports ens1f1
bridge-stp off
bridge-fd 0

And while I'm at it, here's the result of running "ip a"

does "ping 8.8.8.8" work? what about the contents of "/etc/resolv.conf" ?

Nothing happens when I ping 8.8.8.8 or 1.1.1.1, the same thing happens if I try to ping any device on my local network like my router/gateway 192.168.1.1 or my personal computer, 192.168.1.115

Here's the contents of /etc/resolv.conf:

search local
nameserver 1.1.1.1
 
I think I fixed the issue by flushing the ARP cache in my OPNsense router. In OPNsense you can do this in the OPNsense GUIby going to Interfaces > Diagnostics > ARP Table, then click "flush", going to test further to make sure
