I have a problem trying to put my Cisco PIX 515E firewall in front of my network.
My network configuration right now is: I have the internet connected to my Cisco 3500XL Switch over a crossover cable. All my servers are connected to that switch using straight cables.
I tried to disconnect the internet cable and inserted it into the PIX and have the other NIC connected with the Switch (I am using the PIX in transparent mode).
But it's seemed that I have connection only on the INSIDE network (I am using a straight cable). The OUTSIDE (Internet over a crossover cable) it's look like it is not connected.
I thought that it was because the cable is crossover so I asked the DC to re-patch the cable and make it as a straight one. Now on PIX I have connection to the internet (can ping) but the servers behind the firewall doesn't have the connection.
So can anybody give me an idea what is going on?
I set the access list on permit any so I don't think this is an access-list issue.
