how statefull firewall works for udp?

[Tarig Ahmed <tariq198487 () hotmail com>]

Dear All
Hi

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.

Thanks
