Hi I have 2851 router, I am trying to upgrade our internet connection to T3. I am looking to buy a NM-1T3/E3 card for the router. However next year I want to buy a pix 515E and put it in front of the router. So my question is will the NM-1T3/E3 fit into the PIX515E or do I have to get a different card?
I have this problem too.
