Need of H/A for Business

• 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 .

Current Business Situation

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/Active-Passive/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 .

Load balancing scenario

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 .
