It is used for site to site IPSec tunnels using IKEv1 or IKEv2. The admin context is used to determine which interfaces are assigned to which contexts. This is not supported in the 5505 and requires the Security Plus license for 55-X.Ī multi context firewall is one which runs multiple separate firewalls inside a single chassis. Security Contextsīy default the ASA has 2 contexts that can be ran simultaneously. EncryptionĮncryption-DES comes standard on all firewalls.Įncryption-3DES-AES is a $0 cost license that enables 3DES and AES encryption methods. If one firewall goes down, the remaining one becomes Active for both Contexts. This may be used when Primary firewall is the Active firewall for Context A, and the secondary fireall is the Active firewall for Context B. This failover usually occurs without dropping a packet because the connection table is actually replicated between the two units.Īn Active/Active scenario is generally used for multi context firewalls. So if the primary firewall goes down, the standby unit will kick over to active and even take over the active IP. The active firewall will keep the active IP. In an Active/Standby scenario, one firewall acts as the active one and accepts connections going through it. Failover is when two firewalls (which are matching models and hardware) are paired together for redundancy. This is not to be confused with “Clustering”. This specifically means the ASA will only build connections for 10 hosts within the network at a time. The 5505 comes with 10 hosts standard and can be upgraded to 50 or Unlimited number of hosts. This is “Unlimited” in all models except for the 5505. A sec plus license can be applied to remove this restriction. The DMZ interface is restricted to only be able to pass traffic to either the inside interface or outside but cannot pass traffic to both. Suppose these are “inside” and “outside”. Two VLANs can talk to each other without issues. The “DMZ Restricted” term indicates a further restriction. This is stating only 3 VLANs can be created which are then eligible to be applied to an interface. On the 5505 each interface is assigned a VLAN. On the Cisco ASA 5505 you may see a line stating: Now we will cover each of these items in detail.
