USG2000/5100 divided into routers and firewall. In VxR5 version, also have new features to support the VRRP
1. In VxR5 version, can support to configure VRRP by itself and do not need cooperate with the HRP.
n the firewall system, because need to hit the session state, VRRP must open HRP protocol and can support two equipments to backup.
And in VxR5 version, can through the close link state detection, and use command VRRP mode to open VRRP independent operation mode. There is no need to configure HRP, if configure HRP command before, also need to delete. In this environment, can use multiply devices (> 2) to backup, and can linkage other company equipment to support VRRP backup.
2. After close link state test, is not able to use UTM and the come-and-go path based on need the same attack defense (TCP proxy and all connection state detection)
The difference of router application environment and firewall application lead to produce the new characteristics.
This is the product of different application environment, when as a router, weakening the firewall function, reflect the difference. In configuration, need to pay attention to the use of the environment.
