ZyWALL 5/35/70 Series User’s Guide
3As a transparent bridge does not modify the frames it forwards, it is effectively “stealth” as it is invisible to attackers.
Bridging devices are most useful in complex environments that require a rapid or new firewall deployment. A transparent, bridging firewall can also be good for companies with several branch offices since the setups at these offices are often the same and it's likely that one design can be used for many of the networks. A bridging firewall could be configured at HQ, sent to the branches and then installed directly without additional configuration.
