Add a 3rd Interface to PIX 515E

I currently have two interfaces on the PIX but would like to add a third NIC to the PIX and copy the settings on my Outside Interface to the new NIC. Any help would be appreciated.

I am running version 6.3(4) with a Restricted License.

Re: Add a 3rd Interface to PIX 515E

Anybody have any ideas?


Re: Add a 3rd Interface to PIX 515E

if i am not mistaken i am sure it is just to install a network card (of course the specified from cisco) and then boot the pix.

it will then find the network card and add it as a possible configurable card.

however i am pretty shure you can not add the same information om this card as your outside.

it would not work.

Re: Add a 3rd Interface to PIX 515E

Thanks for your response. We have a DSL connection that is a backup to our Fractional T1. This interface is intended to only handle the DSL backup and will either be unplugged or the interface will be set to DOWN unless we lose our T1. I mainly just want to make sure the Routes and groups are still applied to this interface. It will have a seperate IP of course. My first question was to make sure that I COULD add this interface with my current license.

Re: Add a 3rd Interface to PIX 515E


If I recall correctly if you have an (R) lisence in your PIX 515E it will support up to 3 interfaces, if you have a (UR) license it will support maximun interfaces which is a total of 6 physical interfaces. The way to tell your license is by issuing show version and take note the R or UR in output.

So if you install another single 10/100 NIC card and your PIX have R license you should be fine, I would recommend installing a quad card to give you 4 physical interfaces so that you don't waste a single NIC if needing to upgrade to quad card later , you should be able to buy a quad card cheap these days between $100-200, it will save you headaches down the road.
