Hi Guys
Seeing as you gave me such great answers to my last non-windows networking question, i have another...
We've recently spent a couple of thousand pounds on a Cisco PIX 525 Firewall.
Has anyone had any experience with hardware firewalls?
As I understand it, they are meant to be transparent to the hosts communicating to and from the network. As long as the firewall is sitting between our network and the outside world, is there anything that needs to be configured on the machines on the network?
For example:
Several Servers > Network Switch > PIX Interface1 > PIX > PIX Interface2 > Our ISP
The servers have the gateway set as the router of the ISP
Am I right in thinking the two interfaces on the PIX need to be assigned IP addresses on different network ranges, and we employ some sort of routing (ISP will do OSPF) on the PIX itself? Setting the default router on the servers to be that of the PIX interface on the 'inside', so the router is acting almost as a router and a firewall?
We are currently not operating our own BGP router on this particular network.
Please forgive me if that makes absolutely no sense...
Any advice would be much appreciated
