Hello,
I'm having an issue where the client doesn't request a new IP after the
PacketFence Captive Portal registration occurs. A little background:
Cisco WLC 5508 Firmware 8.0.115.0
VLAN 10: Registration 10.0.10.X/24
VLAN 20: Isolation 10.0.20.x/24
VLAN 30: Production 10.0.30.x/24
PacketFence Interfaces:
eth0.10 10.0.10.2
eth0.20 10.0.20.2
eth0.441 172.44.0.10 (Management)
Core Router:
VLAN 10
ip helper-address 172.20.0.3
ip helper-address 172.44.0.10
VLAN 20
ip helper-address 172.20.0.3
ip helper-address 172.44.0.10
VLAN 30
ip helper-address 172.20.0.3
ip helper-address 172.44.0.10
When I connect a client to the "NAC" SSID I am correctly put into VLAN 10 and
given a DHCP address. From there I am able to authenticate my credentials
using Active Directory. RADIUS changes my VLAN and ACL via a CoA packet to
VLAN 30 and Authorize_any. However, even though the client shows up as being a
part of VLAN 30 it doesn't automatically renew so it holds onto a 10.0.10.x
address. I can manually release and renew an then it works, however, this is
not what should happen. I've made a Cisco TAC case thinking it was an issue
with the controller not being put into a DHCP_REQD state after a reassocation,
however, they think it's PacketFence.
My understanding was that if you had "DHCP Address Required" selected on the
Cisco WLC that it would put you in a DHCP_REQD state on the controller after
the VLAN has changed, however, that must not be the case.
Any insight would be greatly appreciated.
