Configuring VLAN in 6500 Switch

Hello all,

I have a Catalyst 6506 that I use for my connection out to the outside
world. My external interface has a routable IP address, and is set up
for NATting. I have multiple VLAN interfaces configured as non-
routable networks, and are also configured for NATting, so that when
someone on one of these networks goes out to the internet, it uses the
IP address of the external interface. This all works fine, but here's
my question:

I would like to set up a "routable" VLAN... that is, a VLAN that uses
routable addresses rather than non-routable ones. There's a few
instances where users need a routable IP address (for IPSec tunnels
and such), and I'd like to consider tackling the problem this way
rather than configuring static NATs. Can this be done? How would I
configure the VLAN's network? The network my external interface is on
is a /26 network, so I'd need this "routable" VLAN to use IP addresses
from the same network. Would I simply break the routable /26 network
into an even smaller network for this VLAN? Is it even worth doing
things this way as opposed to just configuring static NATs?

Any suggestions? Thanks in advance!!! -- BTR
