Dear Community,
We have a cluster of ASA 5540 working in a primary/standby configuration.
We are using source-Nat on this cluster to NAT some multicast streams received from the outside interface to an inside subnet.
Unfortunately, we have an issue when doing the failover between the active and the standby firewall; the multicast stream stops and never starts again.
I would like to know how the NAT function being handled on the ASA cluster , is all the traffic/NAT being handled by the primary firewalls only ?
When we do the failover , my initial though was that In an Active/Passive cluster the other firewall should have all the NAT sessions synched and should take over all IPs and traffic flows.
Hence , Failover should not have big impact on the traffic.
Could someone add the lights on those assumptions ?
thanks and best regards
T
