Upc 240mb port forwarding ipv6

expatoz

Hello
i've just upgraded to 240mb package and have been allocated an ipv6 address which doesn't allow me to forward ports when i log into the router/advanced, i've seen this problem in other threads but they just go off on tangents and i'm wondering if anyone has had any success in
forwarding ports with ipv6
how did they go about
can i send a request in writing to upc (if so how do i go about ie who do i send it to)
if i bought my own router could i assign my own ipv4
I'm totally frustrated with this, its a downgrade not an upgrade and have been hung up on 3 times today by upc help dept.
any help would be greatly appreciated

You can't port forward when you have an IPv6 assigned. It's using ds-lite so basically the NAT is done before it hit's your modem.

Message the UPC reps here and ask to be put on a IPv4 IP address.

hi thanks i finally found someone who agreed to put me back to ipv4 tomorrow, i took his name and location, i can only wait and see, thanks for your advice

Just in case anyone else reads this thread and is having the same difficulty. The easiest way to fix this and switch to IPv4 is to send a PM to UPC: Reps here on boards and they will switch you over:

Kudos to UPC/Liberty Global for introducing IPv6 Internet access.

But it is unfortunate that they didn't introduce it in Dual-Stack mode.

RFC 7368 says "In emerging dual-stack home networks, it is vital that introducing IPv6 does not adversely affect IPv4 operation."

It would also have helped if they had warned customers in advance of its introduction and the likelihood of problems.

Would be interesting to see what would happen if they did this to a large company using their service...
Incidently.. Does any one know of any Enterprises/large companies who use upc.... I don't... Most use o2 or interfusion/Vodafone ECS..

That would have been true 2 years ago but not anymore.
Lots of larger companies, including the one i work for,have moved as UPC offer gig links at the same price as 200 and 300mb links from viatel, vodafone etc.

UPC have a totally differant noc team and equipment on both ends as compared to consumer connections, as you would expect. No chance they would risk forcing IPV6 on business customers.

With Dual-Stack they could have avoided this particular problem completely, assuming that they have enough public IPv4 space to give each customer a single address. I've heard Liberty Global have a shortage. They could try to buy more on the transfer market but introducing so-called Carrier Grade NAT (CGN) is likely a cheaper option than that, particularly as major content providers like YouTube and Netflix support IPv6 and that traffic will bypass the CGN used with DS-Lite.

Exactly. They're doing IPv6 to reduce their ipv4 pool requirement, not to deploy IPv6 and further the internets progress towards transition.

CGN is a big money saver, and lots of ISPs are looking at it.

True, most ISPs are really bad at long term planning of their networks for the good of the Internet. Much easier BCPs than IPv6 like DNSSEC and uRPF checking are still on the to do list. Fortunately to realise the savings with CGN they have to also deploy IPv6 or they'd need to continue investing in ever bigger CGN boxes as the amount of unicast (driven by video) traffic kept growing.

The IETF have been very clever about designing IPv6 into the IPv4 life support technologies like DS-Lite and also LW4over6 and MAP-T (when the latter start to be supported in CPE and provider edge equipment).
