Limewire connection problems
 

I'm using Limewire for the last two years, I had no problem before but since last week Limewire suddenly crashed and since then cannot connect to the web! I just connected briefly for a couple of times and then nothing.
My router keeps sending me a report that:
ACCESS BLOCK Packet without NAT table entry blocked: ICPM (type:3, code:3)
I suspect that is the NAT that blocking my limewire connection!
Do you have any idea how I will overpass it?

- My OS is Windows 98 SE
- I don't have any firewall
- I have 512 MB ram
- I have 10 G total hard disk space
- I have a broadband connection
- My router is a Zyxel Prestige 650 H-E3
- My provider is Forthnet Hellas, a major provider in Greece.
- I'm connecting at my work
- I have the Limewire v. 4.10 and the latest version of Java 1.5.0
- I'm sharing connection with other computers.
- I have done the test with port 6346 and works fine
I have also made port forwarding, UPnP, I have also deleted the preference file and all things to make my limewire "running" again but no luck.
I've also checked everything that is reffering in connection problems in this forum and I have applied almost all the fix and solutions that suggested but nothing seems to work.

I will appreciate any help that you can give me.

Which one are you using, UPnP or manual port forwarding? Manual port forwarding will be more reliable than UPnP. But you'll need to set up a static ip before you forward a port. The instructions will show you how. http://portforward.com/routers.htm
