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
