L'n'S, Shareaza, and Type 3, Code 3...

Just wanted to know what this really means. I keep getting a lot of Destination Unreachable, Port Unreachable (Type 3, Code 3) in my logs. Its like I get one every 10 - 20 seconds or so. I have the 5 rule for Shareaza setup for port fowarding in my rules and I pass the Shareaza Connection Test, so I don't really know what is being blocked so much. I just want to know if it is normal for it to be doing that cause maybe its hurting my download speed. All the blocks with Type3, Code3 say ICMP with Rule - Block Other Packets. What do you think?

This could be normal if you are trying to reach many remote machines on UDP ports and if these UDP ports are not open on these machines.

If you have also a lot of some other alerts, ICMP Type3 Code3, could also be caused by DNS Lookup failures, Look 'n' Stop trying to solve IP names for the other alert. You can deactivate the IP resolution in the options to see if the problem is coming from there (don't forget to press Apply after the change).
