<div dir="ltr">Hi Endre!<div><br></div><div>I tried it too but, L3 do NAT even without needing it (i.e. when using public "routable" address for tenant's subnet)... I see that L3 "thinks" that it always needs to do NAT...</div>
<div><br></div><div>More details, as follows:</div><div><br></div><div>Even using real public IPv4 for tenants (trying to avoid Floating IPs and / or NAT), at the network node, I'm still seeing SNAT rules within the chain "quantum-l3-agent-float-snat / quantum-l3-agent-float-snat"...</div>
<div><br></div><div>How can I disable it, running my cloud entirely by pure routing (i.e. no NAT on L3)...? Making/tagging somehow the tenant subnet as public?!</div><div><br></div><div>Tks!</div><div>Thiago</div></div><div class="gmail_extra">

<div><br></div><div>I do not want to deal with NAT tables anymore, neither "Floating IPs"... This is all $#%#% for me.</div><div><br></div><div><br></div><div>I just read the following OpenStack (I think) doc:</div>

</div><div>Which says:</div><div><br></div><div>"IPv6 Only Tenant Network" <- YES!!</div><div><br></div><div>"The router will not support v6 for NAT" <- YES! PLEASE! When?!</div><div><br></div>
<div>
<br></div><div>NOTE: Please, if you guys are planning to enable "Floating IPs" for IPv6, PLEASE, don't do it! Or, at least, leave it entirely disabled by default...</div><div><br></div><div><br></div><div>Forget about "NAT + Floating IPs" is a priority for my public cloud... I do not want ANY NAT table within my OpenStack environment, never. This is a very important part of my business plan: no NAT, no Floating IPs, public IPs everywhere.</div>
<div><br></div><div>Maybe for Havana?! Is it mature enough, so I can test it today?!</div><div><br></div><div>I just want to give automatically 1 IPv6 /64 for each tanant subnet and be happy... Also, tenants will be able to request more, pre-configured, IPv6 subnets, for sure...</div>
