Hi. Yes. The “short supply” of IPv4 addresses has been well documented – and is a fact. However, Comcast has a ton of 'em. Certainly, we all need to “think IPv6.”
But, I would not use the term “bug,” as you did, to describe Peplink device capabilities vis-a-vis IPv6. I strongly suspect the folks at Pepwave are not unaware of the “v6 issue.” However, as you can see here on the forum, there is a veritable cacophony of requests for improvements, capabilities, fixes, etc. Some of these are really important and are heard over and over. (If you have not browsed the forum, you may want to so so. There are some really smart and involved users, partners, consultants, etc who are very in touch with where “the rubber meets the road.”
My experience is that, in the main, the Peplink folks will “get to” these matters and most of these will be addressed in time. These are products that get better with each FW release. Really, they do. If I had to vote for (1) v6 capability right away or (2) any of the variety of “needed now” capabilities, I’d go for the latter. It’s not that v6 is unimportant – far from it. But, given finite resources, I’d want to see features/“stuff” that makes a difference n-o-w.
So, respectfully, I’d suggest … stand by. I’d venture that “v6” is on Peplink’s roadmap. It has to be. But, it’s not a bug.
