Need of H/A for Business
Current Business Situation
• Current your network has a Single Firewall Appliance , Corporate business
availability depends largely on IT network availability .
• Network security , Proxy , VPN , Email applications are being currently
implemented with a Firewall . Business also uses ISP failover .
• Hardware failure of Firewall results in Network Downtime which effects the
operational continuity of a Business environment .
• Any Network Downtime Results to Business revenue Loss , as the complete
IT Network and internet connectivity gets disturbed .
• Also Remote VPN Users who are connected to the Application servers for HO
data trasnfer get disconnected which results in productivity loss for them .
• Network Downtime also Results in Business image loss for Business .
• Firewall being a very important active component in the IT Setup requires a
disaster recovery plan .
Single Firewall scenario
How to ensure N/W availability
 With High availability or Clustering solution with 2 AnexGATE
Firewall Appliances .
 Firewall Clustering or Firewall Redundancy is the arrangement
of 2 or more Firewalls designed & configured either for Availability
or for Performance or for both.
 Firewalls configured in Master-Slave/Hot-Cold/ActivePassive/Primary-Backup mode, ensures High Availability of N/W.
 So incase the primary Firewall fails , the complete network can
be automatically diverted to the secondary firewall thus ensuring
no business downtime /loss .
How the H/A solution works
Working of H/A Solution
•One Firewall in Cluster is configured as
Primary/Master/Active.
•Redundancy based protocol VRRP is used to detect
failure.
•Detection is based on Heartbeats.
•Heartbeats are token messages that Firewall sends
periodically to each other.
•If Primary stops Heartbeats, VRRP assumes Primary is
not Available.
•Subsequently VRRP selects the
Secondary/Slave/Passive Firewall to become new
Primary.
•The prevalent Primary Firewall owns a Virtual IP.
•This Virtual IP is the Gateway for Peers in the N/W.
When Primary appliance Fails Secondary takes over .
Firewall in Load balancing
•The other approach in Firewall Clustering is Multi-Primary or Load Balancing
mode.This configuration ensures Performance as well as Availability.
•N/W Traffic Flow can be evenly distributed. This results in Performance.
Also in case of Failure, Secondary Firewall takes over all the N/W traffic
management until Primary Firewall is restored/revived.
• This Scenario is particularly useful in Sudden High peak requirements of
network where Network load needs to be shared and ensure performance
for applications like Trading , ERP , CRM or Emails .

How to avoid Business downtime with H/A
1. H/A ensures almost zero Downtime of your Business Network .
2. As a failure of any single Firewall Device involved in H/A design is transparent
to the N/W traffic .
3. In effect, the N/W stays unaffected in the event of failure of any single Firewall
without loss of packets, sessions and more importantly security.
4. H/A Solution Ensures that your IT infrastructure Runs smoothly without any
downtime . Thus ensuring your instant ROI .
