I have upgrade yesterday form version 4.0.21 to 5.0.16, and import the configuration backup. Now, SOME people in the LAN are temporaly blocked with this line in the log in the packet filtering log :
Code:
10.0.0.39 44356 -> 64.254.146.146 80 TCP 60 63 Spoofing MAC ->
The clients machines that are blocked are mainly Linux (2.4 and 2.6), and some others with Windows XP and 2000. It is occuring during some times but randomly.
We are using a simple configuration, with a DMZ and a masquerading LAN. Some servers in the LAN are on the same switch that the DMZ, but on 2 differents VLANs. Network interfaces are configured as standard ethernet interface.
All the intrusion detection are off. I insist that this configuration worked without a hitch before upgrading.
Could you help me to troubleshoot that ?
Thanks.
