Routing Question with 3 Subnets

Tags: Networking

Hello together

I have a problem with my virtual environment. On this picture you can see my configuration: https://amplus.ch/wp-content/uploads/2020/10/proxmox.png

I have a total of three subnets. Where one router with 192.168.1.1 is physical and one virtual router and two virtual machines.

all virtual devices are configured with the virtual bridge vmbr0.

which works:
192.168.10.100 can ping 192.168.1.180
192.168.12.10 can ping 192.168.1.180

192.168.1.180 can ping 192.168.1.1

so basically the connections are there but for some reason i can’t ping the physical router from the virtual machines although the virtual router sees the physical one.

do you see an error? here are some printscreens of my configurations

Check your routes on the physical router

In reply to Routing Question with 3 Subnets

What does your routing table look like on the physical router, your 192.168.1.1?

I suspect that the only route on your physical router is the default gateway, pointing upstream to (likely) your ISP’s gateway. You’ll have to add static routes for the internal networks. On the physical router add:

Destination Gateway
192.168.10.0/24 192.168.1.180
192.168.12.0/24 192.168.1.180
