layer 2 though pix

Hi all

can anyone tell me how this works, we have a connection between out 2 sites, consists of 1 pix 515 and a 3550 each end, a LES circuit is between them, we can put the same ip subnets either side of the connection which means it must be layer 2 through both pix's . how is this achieved, They said its closed user groups or something like that, can anyone explain ?

cheers

Carl

Re: layer 2 though pix

The closed user groups in the scenario means that the the Ipaddress of the subnets can ping each other without passig through PIX.So there will not be any restriction for these subnets. If any other Ip address has to pass through the PIX for reaching others.

Hi Carl,

The same is called L-2 Firewalling or PIX in Transparent Mode .

This could be well achieved with PIX OS 7.0 onwards.

Here is a link with all the details:
