get ip adress ? dont understand this.

but i had to add this two lines to my /etc/ufw/ufw.conf

ufw allow from 192.168.0.202
ufw allow to 192.168.0.202


another trial with iptables needs to load some modules too:

#!/bin/sh

MOKO=192.168.0.202

echo 1 > /proc/sys/net/ipv4/ip_forward
modprobe ipt_MASQUERADE

iptables -I FORWARD -j ACCEPT -d ${MOKO}/32
iptables -I FORWARD -j ACCEPT -s ${MOKO}/32
iptables -I POSTROUTING -t nat -j MASQUERADE -s ${MOKO}/32
