Hello,

that is because packetfence cannot find the ip the system has in the recent dhcp events. I had the impression, one might want to confirm, that some dhcp renew request (when a client wants his old ip) does not update the day when the address is issued within the database correctly. If i am not totally wrong , i have seen the dhcp service or whatever is responsible for that to update the time but not the day, when a client wishes for its old ip.

Solution for my dualboot Windows System  (maybe thats the only reason this problem exists, dualboot?) was to ipconfig /release , then the dhcp request was a normal one, for a new ip, and packetfence dhcpd could recognize the issued ip and show the mac.

Hello,

Where should I be looking if suddenly I am not getting a MAC address to the portal? This device was showing the MAC correctly and now on the portal it shows '0'

Mar 21 14:19:18 localhost httpd_portal_err: Use of uninitialized value in string ne at /usr/local/pf/lib/captiveportal/PacketFence/DynamicRouting/Application.pm line 137.

httpd.portal.access shows the MAC address
