SNAT with oneconnect

it seems okay here. do you have any special configuration?

 configuration

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm virtual bar
ltm virtual bar {
    destination 172.28.24.10:80
    ip-protocol tcp
    mask 255.255.255.255
    pool foo
    profiles {
        http { }
        myoneconnect { }
        tcp { }
    }
    rules {
        qux
    }
    source 0.0.0.0/0
    source-address-translation {
        type automap
    }
    vs-index 3
}
root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm profile one-connect myoneconnect
ltm profile one-connect myoneconnect {
    app-service none
    source-mask 255.255.255.255
}
root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm pool foo
ltm pool foo {
    members {
        200.200.200.101:80 {
            address 200.200.200.101
        }
    }
}
root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) list ltm rule qux
ltm rule qux {
    when CLIENT_ACCEPTED {
  log local0. [IP::client_addr]:[TCP::client_port]
}
when SERVER_CONNECTED {
  log local0. [IP::local_addr]:[TCP::local_port]
}
}

 test by generating 500 requests from 1 client (ab -n 500 -c 1 http://172.28.24.10/)

root@(ve11a)(cfg-sync In Sync)(Active)(/Common)(tmos) show ltm profile one-connect myoneconnect
