sa tingin ko sir ask PLDT bakit ganun yung router nila??? Kasi theoretically you get 1 IP from PLDT then all your computers will access that 1 IP from PLDT... and to segregate your WAN connection (Internet) from your LAN connection (Intranet) then there should be two sets of IP.... One IP from PLDT that may be DHCP/dynamically assigned or Static IP... your Intranet in turn can also have DHCP or Static IP... mejo pangit yata yung PLDT provided router???? or baka iba lang ang naming conventions ng set-up???
