ISP blocks traffic - Their anti-spoofing system - Same VMAC for 3 interfaces

Question asked by Diego Javier Meligrana on Nov 21, 2018

There is a Check Point cluster. Two 5200 series appliances.

Three Internet services connected to the cluster, from the same ISP. They see three IP addresses (each cluster's Internet address for each link) with the same MAC address (checkpoint cluster's virtual mac). That causes their system to activate an antispoofing alert and it periodically blocks the traffic.

Is there any way to set and independant VMACs?

 

Thanks 

 

Best Regards.
