cerowrt-devel is the right place.

Not clear to me what you are doing to "map" a port. Post your firewall
rules? Is upnp in play?

We are painfully aware of this problem. See bug 442. It is the sole
remaining blocker for a stable release.

Are you running with WPA enabled?

After taking a break from this for over a week (in part to build up the
yurtlab, in part because I needed to do some stuff that generated
revenue, and in part because I'd burned out)...

I'll do a new build for everyone and then start intensive tests again...

While felix just apparently fixed a LOT of broken stuff, none
of it looks to reflect directly on the characteristics of the problem
we see. I don't see a memory leak, (fixed in mac80211 just this
weekend) - what I see is possibly a memory corruption on the
crypto side.

I did complete a better build for the archer c7v2 that at least has
a semi-working switch. Ath10k crashes if you look at it funny.

There are very few people on cerowrt-users and I'd just as soon
retire it in favor of not splitting the conversation.
