Comware 7 firewall udp howto

Hi,

 

how can i do same to UDP what "rule 10 permit tcp established" do for TCP?

I mean how i can permit established UDP connections when i have NAT in use?

GE0/0=Internet

GE0/1=192.168.16.0

I need to

- deny udp traffic from internet to GE0/0

- permit traffic fom GE0/1 to internet

- permit traffic from internet to GE0/1 if connection is established, initiated from GE0/1

- multiple protocol's example(IPSEC, IKE, L2TP, DNS, APPE stuff...)

Can i do this with udp-helper?
