Cisco VLAN switching


we have a situation where multiple corporate head quarter LAN communicates to their remote locations using satellite network. The Corporate office is connected to Satellite network operation centre (NOC)using Frame relay network. The WAN routers are 2501. At the NOC, the 2501 routers gets connected to satellite equipment which provides ethernet interface. Each corporate client has their own ethernet interface at the NOC. The Satellite NOC connects the Corporate office to multiple remote sites using satellite network which does either bridging of all remote LANs and connect them to the 2501 WAN router.

Now, the requirement is that all of these remote locations would like to access Internet. we have one 3640 router which is connected to Public Internet.

we would like to connect all of the LAN ports belonging to different corporate customers to this ethernet port on 3640. I am proposing the ethernet port of 2501 and satellite NOC equipment to connect to 2950 switch and configure VLAN for each customer for the security. (We do not want any different corporate clients to see each other.)

we will use access list on the 3640 to block traffic flowing from one VLAN to other VLAN. The corporate customers uses private IP address space. Can the 3640 acts only as gateway to access internet as well as do NAT for all the corporate network including remote sites? Is this a workable solution?

Thanks for your reply.

which should be 100mb interface? My understanding was that the switch can detect 10/100mb port?
