co ASA 5505 Firewall is the smallest model in the new 5500 Cisco series of hardware appliances. Although this model is suitable for small businesses, branch offices or even home use, its firewall security capabilities are the same as the biggest models (5510, 5520, 5540 etc). The Adaptive Security technology of the ASA firewalls offers solid and reliable firewall protection, advanced application aware security, denial of service attack protection and much more. Moreover, the performance of the ASA 5505 appliance supports 150Mbps firewall throughput and 4000 firewall connections per second, which is more than enough for small networks.

Routes Static routes are build in the same way as default routes, in the sense that they have a destination a prefix and a next hop, the difference being that a static route informs the router about specif routes rather than an “any” route like a default route does. An example of the static route would be: Ip route 20.1.1.0 255.255.255.0 10.1.1.0 The first part of the route, the address “20.1.1.0” tells the router that this route specifies the destination of 20.1.1.0. The second part of the route tells the router which part of the destination address in the first part of the address it needs to look at, the “255.255.255.0” instructs the router to look at the first three octets in the...

I’ve been getting a lot of emails asking the following question; “What are IPv6 Unicast, Multicast, and Anycast addresses?” IPv6 Unicast Addresses are used for one-to-one communication; currently there are 3 types of Unicast addresses; Global, Unique-local, and Link-Local. Global Unicast Addresses or GUA’s are used by devices for one-to-one communication across the IPv6 Internet; and every GUA belongs to a defined Global Scope. GUA’s are easy to identify because their values are always 2000 or higher; meaning the first three high order bits of every GUA that is created, equals “001” or 2000::/3. A GUA is made up of three parts; the Global Routing Prefix, the Subnet Identifier...
