Hi, I'm planning a network which will have several networks connected through a Nokia IP Firewall. These networks are implemented on a 3com switches. Since the servers are distributed along several switches I was wondering if it would be possible to build these "DMZ" with trunks/tagged VLAN's and then connect them to the Nokia. Would you consider this design secure? In other words, is it possible to bypass the firewall and communicate directly two tagged vlans?

Thank you for your thoughts.

Derekk.
