Sujet: Re: [DNG] Can't ping outside of my network after having configured a tun tap device
Thanks.

so,maybe this is the solution :

# iptables -t nat -A POSTROUTING -o mlan0 -j DNAT
# ip tuntap add tap0 mode tap
# ip link set dev tap0 up
# ifconfig tap0 192.168.99.1/24
# echo 1 > /proc/sys/net/ipv4/ip_forward


iptables v1.8.9 (nf_tables): DNAT: option "--to-destination" must be
specified

What could be the destination ? thanks.
