[Serusers] Transparent SER in front of asterisk

Hi again, i'm trying to pass all calls through ser, using ipfw on a freebsd machine with two network interfaces. As long as i use the real address (192.168.1.10) of ser on the client, everything works as expected, ser forwards all calls to the asterisk-server (10.10.10.10) on the second network. Using asterisk directly from the clients in the 192.168.1.0/24 network also works. Now i'm trying to use the direct ip of the asterisk server on the clients, but put ser in front of it using an ipfw forward: ipfw add fwd 127.0.0.1,5060 udp from not 192.168.1.10 to any 5060 Basically the same as a transparent squid on a firewall. But ser seems to completely ignore *any* request that hits him. I guess this is because it does not listen on the ip that is really targeted by the clients (10.10.10.10.), can i somehow to answer such requests also?
