when i start to log all packets with NetFirewall it only showes TCP and UDP connections.
does it means that the firewall only manage this two protocols?

NeT Firewall works just below TCP/IP and processes all IP protocols (IP, ICMP, IGMP, TCP, UDP and etc…). Probably you had not any other protocols activity when the log was collected.

when i setup my adapter to “High Security Level”.
does the programm blockes all other protocols which are not listed in the Security Rule table to allow this one ??

“High Security Level” blocks every packet unless there is an allow rule matching this particular packet

what happen with IP, IGMP, RAW….. packets?

If there are no allow rules configured to pass these protocols then these packets are blocked on “High Security Level”.
