I configured our NS5GT for new ISP on the DMZ interface. DMZ interface is in route mode and ADSL modem is setup in bridge mode. I have got policies to allow traffice from
Trust to DMZ and vice versa
Untrust to DMZ and vice versa
Since I configured it I have been receiving lots of IP spoofing alerts and they are different IP to different ports on our Public IP.
I have tried to turn on screening for DMZ zone and most of the features are enabled. It is still causing issue.
Can someone please me with that?
