update: I was able to get the Windows 10 VM onto the internet. Took me forever to figure it out: but the VM was using the wrong setup for the network adapter..

Using the following diagram :

Seems pretty simple to me, Setup the VM to use a Internal Adapter (?) and use Static Routing to hop the connection through the 2 routers and out to the internet.

thoughts?

awesome..good job. Now try it with dynamic routes

I can't see any static routing defined here.

But first, Rule no 1 - always give each device a name and write IPs, subnets and CIDR on the network diagram.

Router 1 (left) is connected to the internet. It routes but that is the default route, right? Everything on it's inside (LAN) is routed to the default gateway on the outside (WAN). The default gateway is either defined as a static IP or through DHCP on the WAN interface. You don't need to add any routes anywhere.

But it's the same with Router 2, connected to the client. It's default gateway for the client LAN and routes everything to the default gateway on it's outside (which is router 1). No routes needs to be defined here either.

If you had both routers on the same LAN it would have been different. Then a client could route some traffic though Router 1 and some traffic through Router 2.

Well, I don't see the exercise as an attempt at setting up static routes but rather an attempt at creating a double NAT setup. But that might be a useful exercise by itself.

Please add names for each router and device and write IPs and subnets you intend to use (for each interface). On the internet side you can write public IP, DHCP is that is what you have.

Nothing about the diagram implies any NATing or double NATing... Though in a home setup, we assume NATing will take place.

Correct. Need more details in the network diagram to be certain.

Likely neither. No static and no double NAT. In theory it's likely single NAT with default routes. But another router is needed so that static to the non-default can be established.

WrCombs

I'm still working on setting up the diagram with the IP's

Question though: the Static routing is defined as "upstream gateway" in PFSense correct?

No, upstream gateway is the default.

I have no idea what you want @WrCombs to accomplish. You should probably draw the network diagram.

I can't see anything in his proposed network diagram that the default route wouldn't take care of. I doubt you meant 0.0.0.0/0 when you talked about setting up static routing.

Also, by default pfSense is setup to automatically identify the default gateway on the WAN and set that up as the default route for the LAN. It's under System / Routing / Gateways and then you have static routes under System / Routing / Static Routes. If you want to see pfSenses' routing table it's under Diagnostics / Routes.

OK, one scenario I can think of is this:

You have an Edgerouter on your LAN, 192.168.1.0/24, that gives you internet access.
Now you want to add your server fleet (VM host) to the LAN and protect them behind a pfSense firewall/router.

All your servers are located on the server LAN, 10.100.1.0/24.

How can you let the W10 client have access to the server LAN, for instance 10.100.1.2, by changing the Edgerouter config?
How can you access the server LAN from your W10 client directly (without sending that traffic over the Edgerouter)?

taurex

Just remember @WrCombs that you can set up static routes both on the client VMs or the router VMs. Most of the time, you'd want this to be set up on your routers because it's more manageable this way plus you can use dynamic routing protocols at scale. However, in some real-life scenarios like remote access VPN with split tunnelling, a route to the secure remote network needs to be added on the client machine itself (with L2TP at least).

Wouldn't updating the Edgerouter Routing Table control that?
if not then I have No idea, This is a static routing environment so, My guess would be to change the routing table to show the next hop to 10.100.1.2 is to go through 192.168.1.123.
Assuming the switch is a dumb switch and is not programmed, I have no idea. How would you ?

The whole reason behind doing this is to understand it, and the more I do it the more and more I get confused, for what ever reason I can't learn networking outside of the basics.

scottalanmiller

@WrCombs said in Project 1 : PFSense Routing:

I think you must be confusing a switch with a router, because the switching being "dumb" (aka unmanaged) or managed has nothing to do with the equation. A switch is a switch, the behaviour is not affected by whether or not it is managed or monitored. A switch, by definition, doesn't route or know where services are located.

There are two approaches here, have a router do the work of telling where data should go, or set routes on the devices.

@WrCombs said in Project 1 : PFSense Routing:

and is not programmed

This would be a "what do these words mean to you" situation. There is no concept of "programming a switch". Nor is there any behaviour in a switch that I can reasonable equate with programming. So I'm unclear what it is that you are picturing. But my guess would be that you aren't thinking of switching clearly as a layer two communications device, but instead feeling like it is a magic box that connects things together so that programming it feels like a reasonable possibility.

But a switch is nothing more than a multi-port bridge. It only knows what MAC addresses exist on each port, nothing more, nothing less. It doesn't even know what an IP address is. There's no human or automation interaction to this job. A switch builds it's list by listening on its ports and it sends traffic by MAC address on layer 2. Switches are non-routable devices and don't have concepts like a default router or routes, because they are layer 2.
