Can the NAT interface of the AR router be configured with multicast


Multicast can be configured on the interface where NAT is configured. NAT is only valid for unicast packets.

Whether the NAT interface of AR router can be configured multicast?
Configure NAT on AR router interface can be configured multicast, but the configuration of the NAT only effect on unicast packets, multicast packets are not supported in NAT.

Configure multicast on the AR router
For the AR router, the configuration roadmap is as follows: 1. Configure the Layer 3 multicast function on the Layer 3 network to implement multicast routing (supported by some AR models). a. Configure a unicast routing protocol to achieve unicast interworking. This is the prerequisite of multicast routing. b. Configure PIM-SM and configure a multicast traffic aggregation point as the rendezvous point (RP). c. Enable IGMP on interfaces of user gateways to learn multicast service requirements of users. PIM generates multicast routes based on IGMP group information and forwards multicast data to receiver network segments. 2. Configure Layer 2 multicast on the Layer 2 network to forward multicast data to Layer 2 outbound physical interfaces accurately. a. Enable IGMP snooping in a VLAN.

which interfaces of AR routers do not support configuration NAT?
LAN side interface (such as VLANIF port) does not support to configure NAT.

Do interfaces conflict when the NAT server and outbound NAT are configured on the AR router
Interfaces do not conflict when the NAT server and outbound NAT are configured on the AR router.

Can outbound NAT and NAT server be configured simultaneously on an AR
On an AR router, outbound NAT and NAT server can be configured simultaneously on an interface. For detailed configurations, see "Internet Access > NAT > Example for Configuring NAT to Enable Users to Access the Internet and Provide the WWW Service Externally" in the Typical Configuration Examples.
