Firewall / Routing Problem Zyxel P2802HWL-I1

Hi,
I want to give access from WAN to LAN to the destination IP: 10.0.0.21:8406
So I configured the follwing Rule (pls see screenshots).
I see in the log that the access does NOT work:
1       11/13/2008 21:49:57      Firewall default policy: ICMP (W to L, Net Unreachable)      xyz.abc.def.gh      10.0.0.21      ACCESS REJECTED
So the external IP (xyz.abc.def.gh) could NOT connect to my server (10.0.0.21) on the LAN
In the Client list of the Router I see that the server 10.0.0.21 is online. From LAN I can connect to 10.0.0.21 but NOT from WAN.
What else do I have to configure?
Any help is VERY appreciated.
thanks

you will also need port mapping/forwarding configured on the router. allow passing traffic to 10.0.0.21 port 8406. Not sure how to do it on this, try having a l ook some setting called virtual server or port forwarding/ mapping or something similar.
In result, every connection to internet address port 8406 to be passed through to server

Hi ricks,
thanks for the tip, I've added a port forward (pls see attachment). But still not working, same error-message:
1       11/14/2008 04:46:21      Firewall default policy: ICMP (W to L, Net Unreachable)      194.187.159.62      10.0.0.21      ACCESS DROPPED

based on the log message, it looks like the router is dropping ping or icmp packet (not 8406)
try enable icmp packets this time

if itstill doesnt work, try do port forwarding for all port+tcp/udp  to 10.0.0.21 temporarily to troubleshoot the issue + keep checking log .

also double check it is port 8406 needs to be allowed..
