Hi, I have a Debian unstable box connected via 33k modem to an ISP, and recieve at approx 3.4kB/s from a local mirror.
Through a 10MBaud coax lan I can transfer at almost 1MB/s. However when masquerading for win98 OR linux boxes on the lan, the throughput drops to around 1kB/sec, and seems to regularly drop packets. I am using 2.4.16 and have compiled all relevant modules (see below for module list). This is my iptable setup (from Masquerading-Simple-HOWTO.gz): echo -n "Starting IP masquerading" echo "1" > /proc/sys/net/ipv4/ip_forward modprobe iptable_nat iptables -F; iptables -t nat -F; iptables -t mangle -F iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A INPUT -m state --state NEW -i ! ppp0 -j ACCEPT iptables -P INPUT DROP iptables -A FORWARD -i ppp0 -o ppp0 -j REJECT (I have also tried the simple: iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE by itself, no difference). Using iptables 1.2.5-6,netbase 4.07 Can anyone suggest a way to track down this problem? Regards, Mark.
