RE: on NAT-PT

[<juha.wiljakka@nokia.com>]

Hi, Pekka!

(firstly, thanks Karim & Jonne for your detailed comments; I read them through and I don't have anything special to add to them at the moment.)

What comes to non-IMS traffic / traffic not going through the IMS (i.e. like described in the GPRS scenario 1), IPv4 type of PDP contexts can be used. However, as I have previously commented, getting a public IPv4 address to the UE can be difficult. Using private IPv4 addresses means use of NATs when contacting a peer node in the public Internet.

Cheers,
	-Juha W.-

However, the issue I believe Margaret (and others) are trying to get to 
is, is translation (=NAT-PT) really required for _other_ services than the 
IPv6-only IMS.

That is, say, web browsing on a 3GPP device.  Or running IMAP to check
mails.  Connecting your laptop to the 3GPP device.  Or whatever.

For these, I believe, the answer is "no, you could get an IPv4 PDP context
for them without problem and avoid translation".  Right?
