We upgraded our internet connection to 300Mb today utilizing a pix-1ge-66 card.
The connection used to be 100mb via the standard 100Mb port that ships with unit.
Since that time, access to "some" of our internal sites stopped.
We own a Class B address space. The problem is not unique to any particular subnet or machine type.
We even have 1 server with 2 ip address. 1 IP can be access, the other cannot.
We have 2 separate RDP servers on the same subnet in the same switch. Again, 1 can be accessed, the other cannot.
I can't come up with any 1 common denominator outside that the gig port is new.
Access from our internal network to the Internet works fine.
I applied the exact same configuration to the new gig port as the old 100Mb port.
I even tried applying an access-list that had "permit ip any any" to gig port.
I suspect something with the firewall or gig port.
If I connect the 300Mb Internet connection to a 3750e gig port; everything works fine.
Unfortunately, it also means we don't have a firewall anymore.
I'd appreciate any thoughts on what else I should be looking at on the Pix.
PS: The Pix is running ver. 6.3(4).
