Has anyone ever tried to upgrade a PIX 520 with 5 interfaces to one with 6 interfaces. I have 1 pix 520 with 6 interfaces and one with 5. I would like to add another ethernet interface to make it 6. My VAR is telling me that they do not sell 2 port ethernet cards seperate so my question is will a PIX 520 work with 1 four interface ethernet card and 2 one interface card.
Thanks
Eric
