I am using Genymotion emulator for Testing My proxy.So I need use iptables to redirect all tcp data to my proxy Port. when I use

iptables -t nat -N REDSOCKS

it prints 'can't initialize iptables table `nat': Table does not exist (do you need to insmod?)'

But when I use

iptables -L

it prints the default table 'filter' complete chains.

'nat' and 'filter' are default tables in netfilter, Why nat table does not exist？

Users of retail Android devices cannot access iptables binary. Even Android OS itself cannot access that binary. Source.

A few general things about routing with iptables.

Dont forget to enable routing .

  1. sudo sysctl net.ipv4.ip_forward=1

    or

  2. echo 1 > /proc/sys/net/ipv4/ip_forward

and

  1. iptables -t nat -A PREROUTING -i $device -p tcp --dport $srcPortNumber -j REDIRECT --to-port $dstPortNumber
