AhnLab TrusGuard Installation Guide
Change the TCP Validation Test setting to 3-Way Handshake Enforcement, as asymmetric routing
may occur.
Active-Active Bridge Mode
You need a L3 switch.
The bottom switch must be in a sub-network with different SIP1 and SIP2.
Set OSPF routing in upper/lower router/switch. You can also use RIP.
The sub-network is used as a gateway, so it uses SIP1.
The HA peers uses OSPF routing for each upper router’s IP address and bottom SIP2.
Do not set the HA interface as it operates using routing protocol.
