Nemeth Gyorgy's ruleset is too complicated. Use the bare minimum :

sysctl -w net.ipv4.ip_forward=1
iptables -t nat -P ACCEPT
iptables -t filter -P ACCEPT
iptables -t mangle -P ACCEPT
iptables -t nat -F
iptables -t filter -F
iptables -t mangle -F
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

Then test the following commands from Windows in order :
tracert -d 130.89.148.12
tracert ftp.debian.org
telnet ftp.debian.org 21
(if you get the server banner then type "quit" to exit)
