Enable TFTP on WAN port

[Atter]

Hi!

I have a big problem. I installed the latest Oleg firmware, configured everything with the help of Wengi's tutorial.
Everything was all right until i want to create a TFTP server on the router.
I installed HPA TFTP and configured it. I tested it from my computer which is connected to a LAN interface. I can get the needed file from the router through TFTP.
But here comes the problem... I connected my modem to the WAN port of the router but it can't able to get the file from the router.
I disconnected the modem, setted up a fix IP for the router's WAN port and tried to get the file from the TFTP but with no success...
I connected my notebook to a LAN port, everything was ok.
My PC was connected to the WAN port directly but i cant get the file...
I tried to ping the WAN IP from my notebook, it's working.
I tried to ping my PC's IP but with no luck.
From the router i can ping the WAN port, the Router's IP and my notebook's IP but cant ping my PC.

I tried it with my PC but I cant able to ping anything nor the WAN, LAN, nor my notebooks IP...

Firewall is enabled,
Enable Web Access from WAN: Enabled
Respond LPR Rewuest from WAN: Yes
Respond Ping Request from WAN: Yes
Enable WAN to LAN filter: No
Added a line to iptables:
ACCEPT udp -- anywhere anywhere udp dpt:tftp

What should I do to enable the TFTP through WAN port?
Please help!

Please help me!
1. I want to access my modem's config page through the router.
2. I want to enable TFTP traffic through WAN port. Because from the LAN side it's working good but not on the WAN side :(
