Hi<div><br></div><div>About your approach for NAT'ing I think that it should work. In fact the firewalling network driver uses the same strategy. </div><div><br></div><div>Given said that, I think that doing NAT at the physical host level is not a good idea. We usually do not assign any public IP to the physical host and just let it bridged to the Internet NIC. Then you may define a VLAN, and create a router VM with a NIC in that VLAN and other one in a Public network. The NAT'ing or any other routing/network facility (e.g. DNS caching, proxy's) can be easily installed in the router VM. Any other VM with a NIC in the VLAN will access the Internet through the router VM...</div>
<div><br></div><div>This approach does not require a public IP for every single host, you may better secure them and better manage your public IP pool (e.g. elastic IP's like functionality....)</div><div><br></div><div>
There are some hypervisor specific features like this one or DHCP that need a different approach in a distributed setting...</div><div><br></div><div>Cheers</div><div><br></div><div>Ruben</div><div><br><div class="gmail_quote">

<br>
</div>It looks like I can just use a remote vm hook and throw any details I<br>
want for the NAT into the vm context and pass them to the hook<br>
arguments. I'll prototype a simple version of this unless anyone has a<br>
working solution or a better idea.<br>
