Hello,
Default configuration for statefull firewall is to allow traffic form TRUST ZONE to UNTRUST ZONE.As I Know those device will use some feilds in the TCP Header. But, how the firewall will handle this policy for none TCP traffics (udp, icmp, and IPsec)?

I think understanding this will help me in the designing.
