<html><head></head><body><div>Hi all</div><div><br></div><div>Seeking some advice from people who do this kind of thing all the time.</div><div><br></div><div>I have an IPv6 prefix (::/48) delegated from the ISP (Aussie BB) and for about the last two years that PD has been routed and accessible from the raw unfiltered Internet. Shows up on the portal etc. It's been configured mostly static, as I didn't have time to try to figure out PD.</div><div><br></div><div>A few days ago that subnet stopped working completely. It's still delegated, and the router can even hand out the delegated addresses, but nothing routes. I've now had multiple responses from the support team claiming that</div><div><br></div><div><span style="caret-color: rgb(46, 52, 54); color: rgb(46, 52, 54); font-family: monospace; font-size: 14.666667px;">></span><span style="caret-color: rgb(46, 52, 54); color: rgb(46, 52, 54); font-family: monospace; font-size: 14.666667px;"> </span><span style="caret-color: rgb(46, 52, 54); color: rgb(46, 52, 54); font-family: monospace; font-size: 14.666667px;">IPv6 /48 subnets in IA-PD address's are only usable for LAN.

Shouldn't a PD normally be routed (why would I bother getting a PD from the ISP if it's not routable space - I'd just use something from fd00::)? Are ABB really enforcing NAT/NPT on a protocol designed not to need it any more? It's still delegated to my nameservers for reverse resolution, which I think wouldn't be needed if it wasn't routable in the first place. And the corresponding IPv4 routed subnet is fine.</div><div><br></div><div>Does anyone else have a PD from Aussie Broadband, obviously on a business plan of some sort is preferred, where the PD subnets are routable? Alternatively - am I just being dumb? I could be dumb, it's a day ending in a Y...</div><div><br></div><div>For reference it's a simple architecture where the PD should be usable on the LAN side of the router, but isn't:</div><div><br></div><div>ABB <---> IPv6 DHCP --[ROUTER]-- IPv6 PD <---> [FW]</div><div><br></div><div>Dave.</div><div><span><pre>-- <br></pre><div>David Rawling - Principal Consultant</div><div>PD Consulting and Security</div><div><br></div><div>t: +61 41 213 5513 | e: <a href="mailto:djr@pdconsec.net">djr@pdconsec.net</a></div><div><br></div><div><font size="2">Please note that whilst we take all care, neither PD Consulting and Security nor the sender accepts any responsibility for viruses and it is your responsibility to scan for viruses.
