I keep receiving the following msg every 10min.

"Deny inbound UDP from 172.16.30.35/137 to 192.168.1.1/137 on interface inside"

I have discovered the 192.168.1.1 ip is located in my ARP Table with the interface set to STATE.Please help.

Hi,

You are getting this message because there is no natting done for 192.168.1.1. It looks like the STATE interface has a higher security level than the interface from which 172.16.30.35 is coming.

Hope this helps!

Thanks,
