Cisco 837 VLAN / Multinet
Hi
I have a Cisco 837 with IOS acting as an ADSL router on a single LAN at the moment. The router has a 4 port hub built in as you probably know.
I've been reading a little about VLANs and multinetting and wondered if I could use this to my advantage in the following scenario:
- LAN 1 - main LAN for internal business use
- LAN 2 - proposed test LAN
Requirements:
- VPN between LAN 1 and LAN 2 using the 837's ports
- Each nework must be completely separate (different subnets) and no machines should be able to see each other unless the VPN is up
- I use NAT on the 837 for getting to LAN 1 VPN Server (Windows 2003 Server) from the Internet. Can I set up a second VPN server operating on a different port on LAN 2 using NAT on the 837?
The purpose of the exercise is to avoid doubling up on routers and phone lines / ADSL fees if possible.
thanks
Rob

The 837 has a 4 port switch. LAN 1 is for internal use and LAN 2 is for testing (including VPNs).
The bottom line is do I need 2 lots of hardware and ADSL lines to achieve what I am looking to do?

Thanks for your comments diegogalletti.
I didn't think the 837 coped with VLANs and I'd been looking at the 1760 so your confirmationis much appreciated.
One question: I think I've seen some switches which support VLAN. Could these be used with the 837 somehow?
thanks

I'm not sure what you have in mind for VPN. VPNs are typically host-to-host, host-to-router, or router-to-router. With only one router, router-to-router makes no sense....
