Single host SNAT iRule

It looks like there might be something else in your class, other than just the IP address, which is being interpreted as a netmask.

If you want to apply a SNAT for specific clients, you can use IP::client_addr instead of LB::server and you can do it in the CLIENT_ACCEPTED event instead:

when CLIENT_ACCEPTED {
    SNAT requests if client_addr is defined in the class
   if { [matchclass [IP::client_addr] equals $::Hosts]} {
      snat automap
   }
}

If this doesn't work, can you run the following commands from the command line or the GUI's console page to list the configuration for the class and rule?

b class Host list all

b rule single_snat list all

Thanks,
