Currently I have a 4402 setup with a guest network vlan. 4402 is connected to a 6509. A port on the 6509 is set as an access port with this guest vlan. This port is directly connected to a Verizon DSL router, which gives out DHCP (192.168.1.X). The DSL router is not set for trunking or does it recognize vlans, everything is going out untagged. This setup works. We are changing providers and I have a spare ASA5505 that I am trying to use. I set it up to the same subnet as the dsl modem was setup (192.168.1.x) and enabled as a DHCP server. All wired connections work fine. When I connect it to the 6509 the guest wireless can not obtain a DHCP address. I can ping the 4402 from the ASA and the ASA from the 4402. I assumed because the traffic was leaving the ASA untagged this would work. Any ideas.
