I have a site in north carolina, its network infrastructure document is as in the attachment.
I got a disaster from that site. The firewall device PIX5505 was dead totally. The only think I know for that device is its internal IP 10.10.28.6. If I plan to buy another device with the same model, how could I make the configuration.
Also, the following is my understanding of the diagram, is it correct? Expecially about the 1605 router's function. Does it have the ability to receive traffic from 10.10.28.0 network and forward them to 10.10.4.0 network in our headquarter?
From the document I have, I believe the PIX5505 which was dead already had been working as both firewall and gateway. All desktop traffic would be sent to PIX5505 first, then it decided if the traffic would go to the internet through T1 router (provided by Paetec) or should forward to internal router 1605. Also I am not sure how 1605 router forwards internal traffic to Bradford since there is only one cable connects it. The only time it's working by using one cable is the original network and destination network are on the same network. In our case, the network in NC is 10.10.28.0, the one at Bradford is 10.10.4.0. I am not sure if it can achieve it.
