Static Routing Configuration

Question

My network looks like this:

The PPTP Server is currently routing all inbound PPTP connections to 192.168.1.0/24, which is good as I expect Device A and Device B to normally communicate with Device X. I can also communicate to Device X from the workstation.

With this configuration, my routing table in the main gateway looks like this:

However, I need to be able to access device A and device B directly from my workstation. ie. ping 192.168.2.10 and ping 192.168.3.10 from my workstation. Is anyone able to provide some guidance on how I can achieve this via static routing or otherwise?

Answer 1

Via static routing you could accomplish your goal with static routing like that:
On device x:
route 192.168.2.10 via 192.168.1.1
route 192.168.3.10 via 192.168.1.1
route 10.0.0.103 via 192.168.1.1
or you can set 192.168.1.1 as the default gateway like this:
route 0.0.0.0 via 192.168.1.1

On main gateway:
route 192.168.2.10 via 10.0.0.101
route 192.168.3.10 via 10.0.0.102

On router A:
route 192.168.1.2 via 10.0.0.1
route 10.0.0.103 via 10.0.0.1

On router B:
route 192.168.1.2 via 10.0.0.2
route 10.0.0.103 via 10.0.0.2
On device A:
route 192.168.1.2 via 192.168.2.1
route 10.0.0.0.103 via 192.168.2.1
or you can set 192.168.2.1 as the default gateway like this:
route 0.0.0.0 via 192.168.2.1

On device B:
route 192.168.1.2 via 192.168.3.1
route 10.0.0.0.103 via 192.168.3.1
or you can set 192.168.3.1 as the default gateway like this:
route 0.0.0.0 via 192.168.3.1

Otherwise you need to install a routing daemon on your devices which perform a dynamic routing protocol such as OSPF.
OSPF itself would be much more effective, because as your diagram pictures, there are some IPs which are allocated dynamically.
The above given static routes wouldn't work anymore when the dynamically allocated IPs change.
