Cisco Sub-interfaces.

[Dave <david.morris () curvalue nl>]

Hi,
        We are being offered a solution which involves VPN private data and internet 
connection over the same physical WAN interface. This interface is on a Cisco 
7200 and would be split into 2 logical sub-interfaces. One for private data, 
one for internet data. After that it is kept seperate on 2 internal LANs so 
is not a concern.

The question is, are there any issues with using subinterfaces for this? Can 
data pass between them? Or are they equivalent in security to physical 
interfaces?

I can find no information on this easily. Has anyone any links, or any 
ideas regarding this?

Thanks for any help.

Best Regards,
                Dave
