Thank you very much "bob@bomar.us" for your reply !
I really appreciate.

I can't use your second idea because my Jaguar box is also a database server and I don't want to send him to the front and to expose him directly on Internet...
So I've tried your first idea and I've setup my jaguar box to be a second gateway and It's partly working. :O)
Ok, my second firewall is connected between my home-router and my hub, but now my two subnets are not speaking together... :O(

I've try to setup both NIC in my jaguar to be on the same subnet but it's not working !?? Sorry for this basic question but;
do a gateway must absolutely has a different subnet on the "Internal NIC" and on the "external NIC" ??

Right now, my connection pattern is :
Internet --> CablModm --> (DHCP)RouterWithHardwareFirewall(192.168.1.1) --> (192.168.1.2)MacJaguarWithNetBarrier(192.168.0.1) --> Hub --> OtherComputersWith 0.xxx IpAddresses.

Some of my networks services like Timbuktu, FileSharing on PCs, network printing, etc are not working now.
But, on the other hand, every computers can succesfully access the Internet ! :O)

Can you tell me how I can make my two(2) subnets speaking together ??
I need my home network to act like one network and to share ressources transparently.
Any advice is welcome !

Thank you very very much !
