Overview of VRRP firewall configuration
To configure the VRRP firewall rules, you must perform two steps in the
SCALANCE S615.
1. Create an IP protocol in the firewall configuration with IP protocol number and
the protocol names. VRRP uses a dedicated Internet Assigned Numbers
Authority (IANA) standard multicast address. The IANA has assigned the IP
protocol number 112 for VRRP.
2. Create 2 IP rules for VRRP communication. VRRP uses the IP address
224.0.0.18 as a multicast address.
Table 4-1
The detailed configuration in the VRRP master and VRRP backup will be covered
in the following chapters.
