Please tell me what steps shall I take (in detail) to arrange my network. Here is the scenario..
Before our domain has 4 different sites. One in New York, One in Texas, 2 are in California. The main headquarter is here in Los Angeles, CA. We used to have frame relay and voice over frame. We have a T1 that is divided for voice and data. Now, all our sites is consolidated to one location only the main headquarter. We do not have frame relay anymore since we only have one network in one location (but has two building in same lot). We still have T1 for voice and data. Due to consolidation we now do not have a router. The only thing we have are the following: router from telecom for our internet and voice. Patch panel, switches and PIX firewall. We also have ISA2004 server. Our network (hardware wise) is so intertwined that I want to simplify it.
What I want to accomplish is put the PIX firewall between router of telecom and my switches, but I am having a hard time analyzing how to do it because of my complicated network topology.
At the moment I have the following:
From Cisco Pix Firewall is a white cable using port Ethernet0 to a linksys hub (old one)
From Cisco Pix Firewall using port Ethernet1 is a blue cable to another netgear hub (old one)
From no 5 port of Netgear is a red cable to Fiber Optic 10base100 TX port
From Linksys hub using port 2 is a yellow cable to #48 patch panel (this is for our internet)
Frolm Linksys hub again using port 7 is a blue cable to no. 12 of one of the switches.
The switches are connected to each other at the back.
How can I make my network topology from router of telecom --> pix firewall --> switches --> users and servers. Please talke note that I have proxy using ISA2004. How can I eliminate all the hubs?
By the way I also have 3 different networks (actually just two).
168 network from telecom company
11 network for pix
10 network for lan
Our proxy server (ISA2004) is in the 10 network.
Please help, how can I accomplish and make this topology simple? Please send email to firstname.lastname@example.org
