To MT Support:
Guys, listen up - when you have a confirmed issue with something as basic and widely used as NAT, it would behoove you to put out a new release - even if as jcremin said was the ONLY fix in it. I read the changelogs, and have noticed that this has been done many times before, so it's not as if it's an uprecedented move.
I also realize it's the Christmas / New Year holiday timeframe, but I posted about this issue almost three weeks ago now, and we still haven't seen 3.18. It's been right at a month since the first post of this thread, and we still have no hints at resolution.
I've already had this issue waste a fair amount of my time in the way of support calls and having to downgrade the problem units to 3.9, and will have to re-invest that time in upgrading clients back to the new release once it's proven to resolve the issue.
MT has also said "if it's not broken, don't upgrade" - which is misleading advice at best. The changelogs rarely indicate subtle benefits (or pitfalls) of a new release versus previous releases, so the only way to tell the benefits is to deploy it in our own network to see how it reacts. In the case of the NAT issue I saw, it didn't show up until it was deployed on a wider basis than my "test bed", and even then it didn't seem to have a pattern until I started collecting more data and reading the forums, by which time it was too late.
For what it's worth, I left Valemount / Star-OS because of the attitude and lack of response to fixing issues that were longstanding and affecting my ability to serve customers. Since that time, there have been a lot more options show up in the wireless equipment and software field. Don't force history to repeat itself.
I wrote back and forth with MT's support, and I agree, it was not very helpful. All they said was that they would fix it in 3.18 and to use 3.13 in the meantime. I asked if they had an ETA for 3.18, and they simply said NO.
Here is a link to download 3.13: http://files.quicklinkwireless.com/mikr ... e-3.13.npk
UBNT had a problem with a firmware that introduced some bugs, and they pulled it right away and released a "fixed" version. I don't know why MT feels they should let people keep downloading broken versions which could potentially be losing us customers and not releasing a fixed 3.18 right away, even if this is the only bugfix it has in it.
