Hi Harold,
here are two suggestions:
As Billie Walsh wrote, the default setup is the modem -> router ->
computer setup. I guess I would go with that (the linksys router is
actually a full computer, so it's all about software and configuration).
What software (firmware) is the router running? The standard linksys
software is maybe too limited for more advanced setups of port
forwarding or packet routing. You can replace the original linksys
firmware by openwrt [1] (I actually run my router with this). Openwrt
can be extended by additional packages. This gives opportunities with
virtually no limits. For easy installtion of an openwrt-webgui, see [2].
With the ips, couldn't a service like dyndns[3] help?

For the modem -> computer -> router solution: Years ago at uni I had a
pc-router, it ran the ipcop firewall distribution [4,5]. That, whenever
necessary, was a snap to install, to configure and to update.

[5] http://distrowatch.com/table.php?distribution=ipcop

That's pretty much my whole wisdom on this matter. Hope it helps.
