I have setup nat port mapping for udp/tcp port 19100 (what i set client to listen to) forwarding to my PC 192.168.1.2. Azureus "health" looks green, and NAT port test is OK. My download speeds are like 3kb/s MAX. I am using WRT54G running RC3. I'm using ISP with 500kb/s downstream speeds and when I did a downlaod test speed which proves no an ISP problem, and I get fast browsing and normal http downloads. I have setup the following rules in iptables:

The thing is that I can setup the same udp/tcp port 19100 on my nokia dsl router, and get full 2mbit speeds (different ISP). Is there some configuration i'm missing or incomplete on the wrt54g??
