Netscreen 25 Help

Hello, I currently have a new Netscreen 25 firewall and I am having trouble with incoming connections, I am replacing a pix firewall and I currently have them set up in parallel since I can't get inbound connections on the netscreen.

I have 2 policies set up for testing one from trust to untrust allowing any traffic out and one inbound with the same just until I can figure out why I am not getting inbound traffic, but I was wondering if someone who is familiar with netscreen firewalls could posibly help or tell me some things to check

thanks
