Since replacing my RT-AC66U with an RT-AC88U i have had problem with intermittent upnp detection
in my living room

I presumed it was to do with the latest MiniUpnpD in merlin but decided to track down the problem today
It turns out its something else

Old Setup (worked fine)
Draytek Vigor 130 VDSL2 Modem in bridge mode (Port 1 into AC66U Wan Port)
Asus RT-AC66U (Port 1 Straight into GS1900)
Zyxel GS1900 24 Port Gigabit Managed Switch (Port 7 20m Straight into)
TP-Link WR-1043ND v1 in AP Mode (Port 1)
TP-Link TL-SG1008D v6 (Port 1 into port 2 of WR-1043ND)

New Setup (intermittent detection of miniupnpd)
Draytek Vigor 130 VDSL2 Modem in bridge mode (Port 1 into AC88U Wan Port)
Asus RT-AC88U (Port 1 Straight into GS1900)
Zyxel GS1900 24 Port Gigabit Managed Switch (Port 7 20m Straight into)
Asus RT-AC66U in AP Mode (Port 1)
TP-Link TL-SG1008D v6 (Port 1 into port 2 of RT-AC66U)

I bypassed the RT-AC66U earlier going straight from the GS1900 straight into the TL-SG1008D
and everything is fine

anyone have any idea why upnp is having problems getting past the ac66u

actually removing one switch from the process didnt fix anything
it just seems to cause a refresh from the loss of link so it worked fine for a bit

its playing up again now
so must be down to the ac-88u

doing a merlin build with stuff i pulled put back in (dpi and such)
failing that i will try a stock asus build

Not really sure what the problem is my AC-66U is fine

AC-88U Merlin stock firmware (not touched by me) fine for first few mins then flakey punching open a port from living room
AC-88U Asus stock firmware fine for first few mins then flakey punching open a port from living room

The only thing i can think of is some setting on the arm builds is slightly different
than on the mips builds that affects going through multiple switches
 
You might have multicasting issues. If you're using 380.59 then try:
Code:
echo 0 > /sys/class/net/br0/bridge/multicast_snooping
Since you're using multiple devices then you might need to experiment and find the correct device/interface. To make it persistent across reboots you need to put it into a startup script (i.e. services-start).
 
I may have found the culprit

I have an odroid c1 running openelec
every time it gets master browser it causes havoc on my lan

it pulls master then doesnt reply to anything
since i forced it to os level 1 earlier

I have noticed devices that have been punching a hole in nat with NAT-PMP
are now useing UPnP (Skype etc..)

Not sure how smb would have anything to do with UPnP problems but atm it seems ok
