How to redirect Branch traffic to DR server if primary server is unavailable.
If anyone can support me to configure the below requirement.
We have installed 2 x NSA 4650 Firewall's (H/O Site, DR Site) and 24 No's SOHO firewalls in remote branches.
We have a requirement to redirect all branch traffic to DR Server if Primary Server is unavailable.
All branch application request coming to H/O Primary server, we cannot configure the application side settings (IP and port ) to DR Server if primary server unavailable .
If any request coming to the primary server, we need to redirect that traffic to the DR Site. without changing the application settings.
