Currently I have a number of remote offices that have the following configuration.
Cisco 1811W (Wireless & Wired) -> PIX 506E -> Internet
These offices access the internet directly and the PIX has a VPN tunnel to our corporate office. Each remote office is identical and currently has a completely flat network using the default vlan.
At our main office I support a number of SSIDs linked to different VLANs on Cisco 1100s. I have a public VLAN that is behind a captive portal that permits internet access for our guests and vendors. I am attempting to find a way to provide a secondary SSID at these remote offices that is completely independent of the office network.
I think the only way I can do this is to create a second VLAN on the 1811W and then VPN that VLAN traffic back to my public wifi/captive portal controller. I can't seem to find a way to originate VLANs on the PIX and trunk them to the 1811W. I have found a number of references to VLAN support on the PIX, but nothing definitive. When I do a 'show ver' on my 506e I don't see VLANs listed.
Any help/suggestions would be much appreciated.
