Someone know if DrawBrigde is able to filter IP packets for one IP 
address rather than the while subnet? I'm looking for a product that is 
able to pick up a packet if it matches the IP of a single host and router 
it to another ethernet network.


    Network A      |   Network B               |        Network C
                   |                           |
                   |                           |
             .-----------.             .----------------.
             | IP filter | --------->  | Firewall/Proxy |
             `-----------'             `----------------'
             eth0  | eth1         eth0=        | eth1 = 192.168.100.200
  Network =        |              192.168.1.1  | 
  192.168.1.0      |                           |

The IP filter shouldn't have to have any IP addresses, if it sees a packet 
that is addressed to the firewalls eth interface 0 (192.168.1.1) that is 
running on 192.168.1.0 network (IP filters eth0) it copies the packet to 
the eth1 interface and vise versa. Uses an access-list. Does such a 
product exist? Is it possible by the way?


best regards, Gunni
