Does PIX support Transparent Mode Firewall?

Re: Transparent Mode Firewall

Not currently for the PIX appliance but this is on the roadmap. FWSM 2.1 code (due in December '03) will support this feature.

Re: Transparent Mode Firewall

One that you can drop in like an ethernet bridge - you do not assign ip addresses to either interface (so it doesn't route). Netscreens can do it, as can linux/bsd boxes.

They are handy when you don't want to re ip address your network to deploy a firewall. Imagine a small company with 100 statically ip addressed workstations on a real class C, connected to a cisco router without the IOS firewall package. Rather than upgrade the router to support the IOS firewall package, you may prefer a more fully featured firewall that can be deployed as a bridge. You would simply configure it, and drop it in place between the ethernet interface of the router, and the uplink to the layer 2 environment for the client machines.

Another upside, is you can have a firewall with no ip address assigned to it - you could this make it almost hack proof, as administration could be limited to physical access. Most bridging firewalls support a management ethernet interface however, for usability

Re: Transparent Mode Firewall

Hi Mostiguy,

Exactly! ;) We have a WAN with several subsidiaries connected to the head office, For security purposes we now want to implement a firewall solution in every subsidiary, and because of the widespread of computer viruses.

Transparent Mode Firewall will be very handy as we do not have to readdress the entire network.
