Virtual Server creation

I thought to use network virtual server because I want to modify the netmask thinking that this is the root cause of problem.

Initially when I set up LTM VE, I tried to use host virtual server only. Anyway I modified my virtual server.

root@f5(Active)(tmos) list ltm virtual vs_http_sandeep

    ltm virtual vs_http_sandeep {
        destination 172.29.0.44:http
        ip-protocol tcp
        mask 255.255.255.255
        pool CCE-Tomcat_pool
        profiles {
            CCE-Tomcat_lan-optimized_tcp_profile { }
        }
        snat automap
    }

root@f5(Active)(tmos) list ltm pool CCE-Tomcat_pool

ltm pool CCE-Tomcat_pool {
    load-balancing-mode least-connections-member
    members {
        172.29.1.51:tproxy {
            monitor CCE-Tomcat_monitor
            priority-group 1
            state up
        }
        172.29.1.51:us-cli {
            monitor CCE-Tomcat_monitor
            priority-group 1
            state up
        }
        172.29.1.51:us-srv {
            monitor CCE-Tomcat_monitor
            priority-group 1
            state up
        }
    }
    monitor CCE-Tomcat_monitor
}
