Wireless VLAN issue
Posted on 2009-05-12
I have a remote site with a guest wireless network in which various Cisco AP's (1100,1200) are all being used in AP and repeater mode for a seperate vlan (say vlan2) which is trunked back to the core switch and then a DSL modem is hanging off of an access port on vlan 2 giving out DHCP addresses in the 10.253.x.x range. It is open authentication with no encryption. All of the AP's are on a (say vlan 1) management network and controlled by IP's in the 10.1.x.x) range. Here's the problem: The AP's are giving clients 10.1.x.x ip addresses and so routing them through the corporate network. Very scary for me. Each AP has the native vlan of 1 and I can reach them all remotely (via WAN.) I have checked the trunks, access ports, SSID/VLAN match etc adn found no cause. Configuration misunderstanding perhaps? We are doing the same thing the same way at our main campus and it works perfectly. Any ideas? Thanks so much to all !!!
