Hi,

What will be rule to redirect the port 80 traffic to sqiud with tproxy table.

I am using kernel-2.6.10 and iptables 1.3.3 and patched bith the
kernel and iptables utility, but still i am getting error if i apply
the rule

iptables -t tproxy -A PREROUTING -j TPROXY --on-port 3128
Unknown arg `--on-port'

iptables -t nat -A PREROUTING -j DNAT --to-dest 172.16.8.5 --to-port 3128
Unknown arg `--to-port'

Regards
Chima
