Hello,
from where are you trying that static NAT IP ? You mention you are unable to access from the LAN. Is the LAN on the "inside" or the "outside" of the NAT router ? What is the exact router configuration ?
For the record, if you are trying to access the configured global static IP address from the a machine on the "inside", the router will not be able to "route" that request from the inside interface to the inside interface. Devices on the inside should use the inside local address for that machine.
Regards
