We are running an ASA5505 with ip plus licensing, which allows us to run multiple vlans (in our case 3: outside, data, and voice). The data and voice vlans (both same security levels) members of an 802.1q trunk on eth0/4, passing the voice and data vlans through the trunk to a 3750 switch.
Our DHCP server resides in the data lan. Is there an equivalent command on the ASA's to the Cisco router command "ip helper-address x.x.x.x" that needs to be placed on the ASA voice interface vlan (svi) to pass these dhcp requests? If not how do we get the dhcp requests to pass through the ASA? FYI the "same-security-traffic permit inter-interface" and "same-security-traffic permit intra-interface" are configured on the firewall.
We do not see any entries in our dhcp server scopes for the Cisco phones, but the phones are registered to the off subnet Call Mgr and are using addresses in the range of the voice dhcp scope on the server.
Odd one for sure....any help is appreciated.
