Add Ethernet adapter to Cisco PIX 515E

Hi All,

My company's network is behind a PIX 515E.  We are going to be adding an additional ISP for redundancy since we have mission critical app's running on our network.  

We have two subnets.   I would like one subnet to continue using the current ISP, and force the other subnet to use the new ISP.

So, I'm going to purchase an additional NIC for the PIX (Anyone know what make/model I should use?)

And then force the 2nd subnet to use the new interface (which will be the new ISP)

Does this sound reasonable? What make/model NIC should I install? Will it be PnP?

Hi,

you need:
PIX-1GE-66= or PIX-4FE-66

http://www.cablesandkits.com/cisco-pix4fe-10100-port-fast-ethernet-card-p-1401.html

Don't forget the static nat statements not working with backup lines!

Best regards,
Istvan

Do you know if the new card will be detected automatically?

What do you mean the static nat statements not working?

Thanks

I was going to do something like this:

interface2 auto
nameif ethernet2 outside2 security0
ip address outside 2 X.X.X.X
alias(inside) 10.242.55.253 X.X.X.X 255.255.255.255

interface2 = new ethernet card
x.x.x.x = IP assigned by new ISP
10.242.55.253 = IP of where 2nd subnet will be coming from that I want to force to the new ISP.

How does that look?

At this time I don't want a failover configuration.  Any advice regarding my previous post?
