Proxmox/OVH - no route added to GW after upgrade to 2.5.0

Problem

After updating a Proxmox VM on OVH to 2.5.0 I was left with no internet access.

Upon further inspection I noticed there was no route to the gateway(on an different subnet) being added.

I have added a working solution below if it helps anyone else out that is finding themselves in a similar situation.

Failed Solutions

I tried deleting the WAN gateway from the GUI and then re-adding it making sure the Use non-local gateway option is selected. Upon doing this no route is added to the gateway that resides on the different/external subnet.

Working Solution

Login via SSH and then add the route manually:

route add -net XXX.XXX.XXX.254/32 -iface vtnet0
route add default XXX.XXX.XXX.254

Replace XXX.XXX.XXX with the IP of your OVH box substituting the host part of the address with 254.

Once WAN connection is back up, install the ShellCmd package and add the commands listed above to automate this on system boot.

Question

Is there a to make this work through the GUI on 2.5.0 without using the ShellCmd package as this seems a bit of a hack job?

This same setup worked on 2.4.5.

I have tried looking for any new advanced options in the GUI that might be causing the issue but can't find any.

Thank you!

I got the same problem with the same architecture and it was driving me crazy !

The workaround works for me too.

The default route set in the GUI is never installed in the routing table.

You can install the System Patches package and then create an entry for a97987a5d1df8219f40433270fce0e3ef49345dc to apply the fix.
