Hi

Try to upgrade firmware if there exists an newer version on Cnet's homepage.

As for portforwarding i found an step-by-step manual on the web:

http://www.portforward.com/english/routers/port_forwarding/CNET/CNAD804-NF/WarezP2P.htm

Can you successfully access the webserver on port 8080 within your LAN, inside the router ?

khacduyst,
something seems strange about the info you gave, namely the address 58.186.114.23
Please look at this network diagram to see if it is correct or not:

[tomcat  ](10.0.0.5)------------------(10.0.0.2)[router Cnet  ](58.186.114.23)----------[Internet??]------(210.245.24.4)
[server   ]                                                   [CNAD804-NF]                                                            [where is this?]

Also, I notice that the router seems to be using the "br0" interface to connect to the "10.0.0.0" network,
is that an ISDN interface?  I would have though you should be using an Ethernet interface instead.
You should not plug an Ethernet cable directly into an ISDN port, even if it looks like it fits.
