Companies are more and more
dependent on their Internet Service Providers (ISP) to
conduct businesses over the Internet. To ensure business
continuity, customers seek can use multiple ISPs to
reduce the risks of a single ISP failure.
Check Point ISP
Redundancy enables reliable Internet connectivity by
allowing a single or clustered VPN-1 gateway(s) to
connect to the Internet via redundant ISP connections.
As part of standard VPN-1 installation, it offers three
modes of operation:
Primary/Backupmode connects
to an ISP through the primary link, and switches to
a backup ISP if the primary ISP link fails. When the
primary link is restored, new outgoing connections
are assigned to it, while existing connections are
maintained over the backup link until they are
complete.
Load Sharingmode connects
to both ISPs while sharing the load of outgoing
connections between the ISPs. New connections are
randomly assigned to a link. If a link fails, all
new outgoing connections are directed to the active
link. This configuration effectively increases the
WAN bandwidth while providing connectivity
protection.
Primary/Dial-up Linksallows
ADSL, ISDN or dial-up to be configured as backups to
primary links.
Check Point Advantage
ISP Redundancy
requires no additional hardware installation. This
solution does not need separate management software.
Configuration and monitoring of ISP Redundancy is
integrated with SmartCenter management suite.
