Hi,

I'm running on my server minissdpd-1.2, miniupnpd-1.7.20120824 on gentoo/linux and on all machines miniupnpc-1.7.20120830.

The server has a wifi and an two wired interface. eth1 and wlan0 bridged as br0 and eth0 as connection to External.

I'm starting
minissdpd -i 192.168.1.1 # <- ip on br0

my miniupnpd conf:

Code:
ext_ifname=eth0
listening_ip=br0
port=0
minissdpdsocket=/var/run/minissdpd.sock
enable_natpmp=yes
enable_upnp=yes
upnp_forward_chain=forwardUPnP
upnp_nat_chain=UPnP
lease_file=/var/log/upnp.leases
bitrate_up=500000
bitrate_down=3000000
secure_mode=no
system_uptime=yes
notify_interval=60
clean_ruleset_interval=600
uuid=4735fda9-59bd-470f-a1e5-b3f2ba6c1d1a
serial=12345678
model_number=1
allow 1024-65535 192.168.1.0/24 1024-65535
deny 0-65535 0.0.0.0/0 0-65535


If I'm run upnpc on server it works fine - always: upnpc -m br0 -s
If I'm run upnpc on a client it works fine for some minutes after restart. But then It can't find the igd anymore:

Code:
$ upnpc -m eth0 -s

Go to URL1 or URL2
for more information.
List of UPNP devices found on the network :

 st: upnp:rootdevice

UPnP device found. Is it an IGD ? : http :// 192.168.1.20:34257 /   ## <<- no it isn't!!
Trying to continue anyway

On debug log of minissdpd it shows first correct requests:

Code:
SSDP M-SEARCH from 192.168.1.20:56381 ST:urn:schemas-upnp-org:device:InternetGatewayDevice:1


but after a while no log entry is shown if I try to call upnpc on a client.

Only solution to make it work again: stop miniupnpd, stop minissdpd, start minissdpd, start miniupnpd

Any ideas what I can try to find the problem?

Ok, if I'm put my br0 interface in promiscuous mode it works. I tried to set an multicast route (described here: http://linux-igd.sourceforge.net/documentation.php) but with no effect.

Looks like a bug in minissdpd...
maybe you can run minissdpd in gdb, wait a few minute for him to hang and see in gdb where it is blocked ?

mhm minissdpd don't crash. So I don't get a backtrace in gdb. I don't know if minissdpd really hangs because requests from same host works fine.

Is it possible that some network stuff is wrong because it works in promiscuous mode.


(I'm ~ 1 week afk - my reply may need some time)
