Hello! I am using a combination of iproute2 (source based routing) and iptables (NAT Iptables Version 1.2.6a-5). The problem is that I have big performance problems. The maximum download speed per user is about 5kb. We can only use our existing line to the ISP by about 20%, and thats not an ISP problem. Need help!
