Routing to multiple networks on Proxmox?

Question

Virtualization

How to configure routing through 2 physical interfaces?
1 looks to the local network, the second - to the Internet. And there is a virtual machine that acts as a firewall, proxy and dhcp server?

Currently:
$ cat /etc/network/interfaces

auto lo
iface lo inet loopback
iface eno1 inet manual -> to provider (own ip & gw)
iface eno2 inet manual -> included in local network

auto vmbr0
iface vmbr0 inet static
address 192.168 .100.12/24
netmask 255.255.255.0
gateway 192.168.100.1
bridge-ports eno2
bridge-stp off
bridge-fd 0 #Internal
network

In this configuration, everything works only in the lok. networks. How to register the path to the virtual firewall? I do not understand. Bridge with a gate on the dip - does not work, tk. the default gate is already there. Register without a gate? And on a virtual machine how to resolve all this?

Answer 1

I have it set up as a test environment like this...
Proxmox interfaces look like this:

A virtual machine that distributes addresses on the local network and VM and serves as a gateway with these interfaces:

Proxmox network settings are as follows:

You should have something like this. Try it.

Answer 2

Thank you! There is a basis for reflection. And in passing: is it true that the bridge connecting the external interface (physical) and the virtual machine broadcasts all traffic to the virtual machine and, accordingly, the firewall (and port forwarding, etc.) can be built on the virtual machine? Those. the host will be safe for attacks from the outside?

Answer 3

just raise individual breeches for everything

Answer 4

Use mac to get started

Answer 5

Turn on the brain and use the search.

Answer 6

Isn't this kind of thing drawn in a vector?

Answer 7

You draw everything in vector (shapes, curves, icons).
You don't need to know dpi and ppi.

You draw in 1x, that is, 375 × 667
On a mobile device under android, you check it using Pixlr Preview. Or with the help of Marvellapp.com Photoshop itself can
convert a vector to svg or png @1x @2x. Look for "generating @2x assets photoshop" instructions. Perhaps Zeplin can do this (then everything is easy and nothing needs to be done)
