Router question

[#1]

I have a DG834G.3 wireless router.I have just been browsing through it's files and I think i noticed an anomaly.
  On Router Stats and Firewall rules the last digit of my IP address is (1) however on the UPnP(which is ON) the last digit is (2).
  Am I correct in thinking that they should all be on the same address?

Shouldn't imagine so. On the Router Status page, the IP address under LAN Port is the IP of the router on the local network whereas, the IP on the UPnP page is the address of an attached device on your network i.e. your computer.
