hello Sir. Thank you for your help. [No Pool] I know that when the [Address Translation ] option is [Disalbed], it works normally. I would like to know what Flow does not wor...
Address Translation, when checked (enabled), that the system translates the address of the virtual server. When cleared (disabled), specifies that the system uses the address without translation. This option is useful when the system is load balancing devices that have the same IP address. The default is enabled.
your VS not have a pool, when you enable Address Translation, the system can not translate the clientside dst ip to serverside pool member address
tcpdump packet find icmp type 3 code 9 official definition is "Destination network administratively prohibited"
Also with TCP RST logs enabled I think in the LTM log it will be "No server selected" https://support.f5.com/csp/article/K13223.
