CRS questions about MAC authorization and DHCP spoofing

Mon Jun 04, 2018 1:58 pm

Hi,

does anybody know if/how it is possible to:

1. authorize MAC address of the connected computer based on RADIUS reply and then assign port to specific VLAN?

2. detect DHCP snooping on specific port and take an action based on that (ie disable port)

thanks in advance

after some investigation:

re 2:
still no success for DHCP snooping configuration but two options to address issues with malicious DHCP server in L2 segment:
- Protocol Level Isolation described here: https://wiki.mikrotik.com/wiki/Manual:C ... _Isolation
- DHCP server alerting described here: https://wiki.mikrotik.com/wiki/Manual:I ... ver#Alerts
