[pve-devel] qemu nat mode and rate limiting ?

[Alexandre DERUMIER]

Is it this setup ?: http://www.linux-kvm.org/page/Networking

"
iptables/routing
-----------------

Hostside: Allow IPv4 forwarding and add route to client (could be put in a script - route has to be added after the client has started):

sysctl -w net.ipv4.ip_forward=1                 # allow forwarding of IPv4
route add -host <ip-of-client> dev <tap-device> # add route to the client

Clientside: Default GW of the client is of course then the host (<ip-of-host> has to be in same subnet as <ip-of-client> ...):

route add default gw <ip-of-host>
"



Because I don't see ip address on tap, but only a route

That is not related to iptables. We just need to create a tap device, and assign an IP address 
to it (and maybe run a dhcp server for the tap device).
