Is anyone familiar with network object group synchronization between two asa's that are separate (not a failover pair)? I understand that this might be possible with a script but what I want to do is to have the changes to one network object group replicate the changes to the similarly named network object between two remote ASAs. The remote ASAs have internet failover via BGP and the public IP's are the same.
Of course there is the manual or script option that you mentioned.
There is also the option of the "write net" command to pull the config from a central site.
And also AUS server option where changes are pushed to the ASAs together from a central AUS server.
I hope it helps.
