On the Multicast Routing (PIM-SM) > Interfaces tab you can define over which interfaces of Sophos UTM on AWS multicast communication should take place.
To create a new PIM-SM interface, do the following:
On the Interfaces tab, click New PIM-SM Interface.
The dialog box Add PIM-SM Interface opens.
Make the following settings:
Name: Enter a descriptive name for PIM-SM interface.
Interface: Select an interface that is to accept PIM and IGMP network traffic.
DR priority (optional): Enter a number that defines the designated router (DR) priority for the interface. The router with the highest priority honors IGMP requests if more than one PIM-SM routers are present on the same network segment. Numbers from 0 to 232 are possible. If you do not provide a priority, 0 is used by default.
IGMP: Select the version of the Internet Group Management Protocol that is to be supported. IGMP is used by recipients to establish multicast group memberships.
Comment (optional): Add a description or other information.
The new PIM-SM interface is added to the interfaces list.
To either edit or delete a PIM-SM interface, click the corresponding buttons.
