Network Routing Question

Not really a programming question, but this forum is the closest I could find.
Here is my scenario....
There are web-enabled 'systems' that are deployed with cellular modems in them
CellModem1 (10.1.1.0/24)
LAN IP is 10.1.1.101
WAN IP is dynamic, resolved to a dyndns
CellModem2 (10.2.2.0/24)
LAN IP is 10.2.2.101
WAN IP is dynamic, resolved to a dyndns
They connect site-to-site with a vpn router, Router1
68.1.1.1 <WAN Router1 LAN> 10.0.0.1 (subnet here is 10.0.0.0/8)
There is a second router here
68.2.2.2 <WAN Router2 LAN> 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 10.0.0.10
NIC2 192.168.15.10
Web traffic is routed thru Router2 to the CentOS on NIC2
JohnnyUser will point his browser 68.2.2.2 and see our web page
JohnnyUser may choose a link on the webpage that is special
We want that special link to redirect him to the web-enabled device that lives behind CellModem2 at 10.2.2.102
Is the network topology I've outlined workable in this situation?
Suggestions for a better solution?
Thanks!!!
