V1.37 Its great that Interface Rate Limiting has been added works on interfaces of a bridge but you must remove them to set the rate limit to add them back which is fine.

I could select Private DNS Server then and then it mentioned "query via tunnel". In FLEX H Series I don't have that option anymore, can only select one…
