I have 4 Cisco Aironet wireless APs controlled by a Cisco 2504 wireless controller. The wireless users are connected to a pfsense firewall running on Hyper-V which acts as a firewall and DHCP server. The wireless controller advertises two SSIDs one for staff (on VLAN 30 - radius and ldap auth) and one for guests (on VLAN 20 - local user auth). The wireless controller is not acting as a DHCP server.
I just started at this company and today I had to recover the enable password on the core switch. Done and rebooted. Everything seemed to come back up fine. Later in the morning a user complained that their iphone could not connect to the wireless. Wheel keeps turning.
I brought up a laptop and was able to connect (and even authenticate via the controller) to the wireless but received an error stating that the DHCP server could not be found.
The pfsense firewall is up and running and seems to be in good shape. The wireless controller has an IP address for the internal network as well as the VLANs 20 and 30. I was able to ping the VLAN20 address but no the VLAN30 address.
The pfsense does not have an internal IP and I cannot access it via web gui. It runs in shell only in Hyper-V.
I am at a bit of a loss to determine what is going on. I was not able to find a dhcpd running on the pfsense nor could I find a rc script to start or stop it. There is a config file at /var/dhcpd/etc/dhcpd.conf that is configured with the right settings.
Can someone help me out with this? Max points will be awarded.
