In my network has 1,600 computer and ASA 5510 is Default-Gateway. The ASA performs NAT, routing, firewall and vlans. Altogether I have about 20 vlans.
My question is about de ASA 5510. This ASA 5510 in my network is recommended for all tasks?
I´m not Analyst Security, I´m networking administrator and the people of security say that the firewall is recommended. But the firewall anytime has 80% CPU.
I´m very worried in my network, and in this moment my network is slow.
When I test computer that is in the same vlan, I don´t have slowly and accesses the network and file transfer is fast. Different the other acess to use the structure of the firewall.
I think the firewall is not recommended or are you wrong setting.
The autentication in domain, access to file server and all taks using the firewall..
Today the Firewall have IOS --> 8.2.2
