BB0040 ? Does anybody have one ?

This may not be the place for this but i'm desperate.
Running a Gnet BB0040 DSL modem that has a simple port forwarding
command for port 80. For my apache web server which is behinf the modem after a hub.
ie:
nat inbound list: shows:
inbound list
# Interface Port/proto New IP addr Flags
1 ppp_device 80/tcp 192.168.1.101
BB0040 nat> Operation Mode : G.DMT

This doesn't work ? Any idea's ?
