can't initialize iptables table 'nat' under qemu
The error message:
iptables v1.6.1: can't initialize iptables table `nat': iptables who? (do you need to insmod?)
states that the nat
table cannot be found.
This means that your operating system is missing support for NAT. You can load the NAT module by running modprobe nf_nat_ipv4
.
