Server accesably from WAN but not from LAN

Hi I have the following "problem":

I have a webserver behind my router, this router does NAT for the
required ports. This works realy well for connection from outside.
However if a request is made from whitin the same LAN, the server is
unreachable. Now I think it has something to do with the fact that the
router only uses NAT for the external interface.

I might want to change something in its routing table or NAPT table, I'm
just not sure what.

more info:

router: Thomson Speedtouch 510
router ip: 10.0.0.138
server ip: 10.0.0.12

Some napt entries:
Nr Type Inside address Outside address Prot State
1 Temp 10.0.0.12:80 unspecified:80 tcp NONE
2 Temp 10.0.0.12:119 unspecified:119 tcp NONE

ipaddess table
Intf Address/Netmask Type Translation
BaByXL 84.******/24 Auto napt
eth0 169.254.73.159/16 Auto none
eth0 10.0.0.138/8 Extra none
loop 127.0.0.1/8 Auto none

(I tried to set translation for eth0 to napt but then my connection to
the router died as well as my internet connection ofcourse.)

thanks for reading,
Yuri
