Network and Routing Question

*** This project does not require you to setup any networking

*** We are only looking for advice and suggestions for our network setup

>>> Networking

We will have web-enabled 'systems' that are deployed with cellular modems in them

CellModem1

- LAN IP is [url removed, login to view] (10.1.1.0/24)

- WAN IP is dynamic, resolved to a dynamic dns

CellModem2

- LAN IP is [url removed, login to view] (10.2.2.0/24)

- WAN IP is dynamic, resolved to a dynamic dns

They connect site-to-site with a vpn router

Router1

- WAN IP 68.1.1.1

- LAN IP 10.0.0.1 (subnet here is 10.0.0.0/24)

There is a second router here

Rotuer2

- WAN IP 68.2.2.2

- LAN IP 192.168.15.1 (subnet here is 192.168.15.0/24)

There is a webserver/ftpserver/router CentOS box here also

It has two Nics

NIC1 [url removed, login to view] connected to Router1

NIC2 [url removed, login to view] connected to Router2

Web traffic is routed thru Router2 to the CentOS on NIC2

>>> Functionality

JohnnyUser will point his browser [url removed, login to view] and see our web page from the web server on the CentOS server

JohnnyUser may choose a link on that webpage that is special

We want that special link to redirect his browser to the web-enabled device Unit2 that lives behind CellModem2 at [url removed, login to view]

Also, if network traffic arrives at the WAN of Router2 and the destination port is 45678, that traffic will need to be routed to Unit3 and return traffic from Unit3 goes back to the User

>>> Current Status

VPN tunnels are up and working from cell modems to Router1

I can ping all Units and receive replies from the CentOS computer

>>> Questions

Can this network topology work as we want it to?

Can the CentOS be setup to route web browser traffic between NIC1/NIC2?

What changes should be made?

What suggestions do you have for a better solution?

What problems could you expect?
