Thanks. We'll let you know when a new response is added.

I presume this is a ScreenOS model of firewall ? Search for Transparent mode in the documentation. The following is taken from the Concepts & Examples ScreenOS Reference Guide, Volume 1.

Management
set interface vlan1 ip 1.1.1.1/24
set interface vlan1 manage web
set interface vlan1 manage telnet
set interface vlan1 manage ssh
set interface vlan1 manage ping

Interfaces
set interface ethernet0/1 ip 0.0.0.0/0
set interface ethernet0/1 zone v1-trust
set interface ethernet0/3 ip 0.0.0.0/0
set interface ethernet0/3 zone v1-untrust

V1-Trust Zone
set zone v1-trust manage web
set zone v1-trust manage telnet
set zone v1-trust manage ping

Addresses
set address v1-trust FTP_Server 1.1.1.5/32
set address v1-trust Mail_Server 1.1.1.10/32

Route
set vrouter trust-vr route 0.0.0.0/0 interface vlan1 gateway 1.1.1.250 metric 1

Policies
set policy from v1-trust to v1-untrust any any any permit
set policy from v1-untrust to v1-trust any Mail_Server mail permit
set policy from v1-untrust to v1-trust any FTP_Server ftp-get permit

Mail_Server and FTP_Server are just examples of hosts protected behind the firewall (Trust), and the policy allows specific services across the firewall from the rest of the network (Untrust). vlan 1 is what is used in a transparent firewall as the management address, this is the only reason it is configured.
