did you have a solution to your question? I need to do that exactly.

Same question

Use a curl command but instead of using url just type the backend server ip

Jucker, if you haven't found your answer yet I recommend reading the solution articles on each function. However, at a high level VLAN failsafe uses arp at layer 2 to determine if communication is occurring over a specific VLAN. Gateway failsafe allows you to have a pool of servers at or beyond the default gateway to determine if it is able to route traffic. Network failover is more or less just heart beat validation between devices in a ha pair. support.f5.com/csp/article/K13297 support.f5.com/csp/article/K15367 support.f5.com/csp/article/K75303031 support.f5.com/csp/article/K2397

Hi Sam, I apologize for the delayed response. Have you done any captures on the pool members themselves to see the HTTP response codes they are sending when the monitor sends the request? Also, to narrow down your capture, remember health monitors use a self IP and not a SNAT IP. If using SNAT, the floating (SNAT) IP will be the client translated address where as the self ip does health monitoring and other system functions.

Hi James, sorry for the delayed response. You are right, I didn't get into the details on this since I was really just trying to keep it high level. With that, you ask a great question. The Unhandled Query action is when the query does not match a wide IP or a local zone. Below are the recommended settings for unhandled query actions. F5 recommends that you configure the Unhandled Query Actions setting in the DNS profile as follows: Use the Allow setting (default) if you want to load balance the requests to another authoritative DNS server in the environment, or to local BIND on a GTM-licensed system (if local BIND is enabled using the DNS profile). You should also use the Allow setting if the GTM system sends DNS queries to a pool of DNS resolvers. This setting is also required when DNS cache feature is set to Transparent. Use the Drop setting if the GTM-licensed system is configured as an external, authoritative DNS system. The Drop setting provides maximum protection and security for unmatched packets for systems processing external DNS queries. Use the Reject setting to return a REFUSED status for the DNS query. Use the Hint setting to return a list of the root name servers for the DNS query. Use the No Error setting to return a NOERROR status for the DNS query.

Hahaha, I thought audio was a big start! Now my face? Ahh man, this is getting serious! ;)
