I'm using an SMC Barricade 7004BR cable router to do exactly this.

Set the router's WAN port to the static IP address given to you by your ISP.
Set the IP address of your VMS system to a static address on the internal
network, usually 192.168.x.x, set VMS's default gateway to the IP address of
the router, usually 192.168.x.1 or 192.168.x.254. Set the DNS server to the
IP address of your ISP's DNS servers. The cable router is a NAT box. It
should now allow the VMS system to get to the internet. Outgoing connections
will "appear" to be coming from the static IP address on your routers WAN
port (that connects to the cable modem).

The Barricade makes this very easy. It has a specific menu for static WAN
addresses. You can also set specific DHCP ranges and leave the others in the
internal network as static addresses to handle VMS's lack of DHCP client
capabilities.

Now, to allow incoming connections, such as telnet, to the VMS box, there
should be a setting on your router for a "DMZ" host. Set it to the
192.168.x.x address of your VMS server. All incoming connections will be NAT
translated and sent to your 192.168.x.x address. If you need to allow
connections to other machines on your internal network you will have to
define specific ports to other 192.168.x.x addresses for the other machines.

www.Egghead.com and www.buy.com are selling the barricade for around $130
with 4 10/100 switch ports, serial console port (believe it or not, you can
plug a vt terminal into it for setups and firmware updates!) and a parallel
printer port that creates an LPD service for a shared network printer.

Check www.techbargains.com for coupons before you visit buy.com. Get another
$15 or so off your first order.
