from where HOTSPOT HOSTS come from ?

hello every one , i wish you are doing fine
i recently implemented an HOTSPOT on the new HEX S router , and i am willing it to use it along with an RB2011 , this is not the matter
i did the following configuration on the HEX S for the HOTSPOT with load balancing

/interface bridge
add fast-forward=no name=LAN
/interface ethernet
set [ find default-name=ether1 ] speed=100Mbps

what does this do is that i create a bridge and i did set hotspot on bridge LAN , and i did load balancing using PCC
so what i am seeing is very bad perfermance and some werd behaviour , if i start a bandwich thest , it starts and emidiatly disconnects
2nd ; i see the follownig hosts and some times i see google IP address as a host ??
3rd , mostly if i am surfing some sites responds fast , but some times takes long and some times i even have to refresh so many times ?
here is the diagram of the network , tell me what can be wrong ?
