Igm proxy, wdtv looses media server

mweber

hello forum,

i use at home pfsense 2.0.1-RELEASE (i386) on a alix board (3 ethernet ports).
1 ethernet is WAN, 2nd LAN, 3rd OPT1

LAN (static) IP 192.168.2.70
OPT1 (static) IP 192.168.3.1

I go the Services / Igmp-Proxy
and set:

LAN upstream 192.168.2.0/24
OPT1 downstream 192.168.3.0/24

on LAN Network is a "mediatomb" running.
and my WDTV LIVE HUB (mediabox) is connected to the OPT1 subnet.

Without IGMP PROXY my wdtv live hub box wot see the mediatomb server.
With activated igmp proxy yes.

so i start to play a HD movie from mediatomb on LAN (192.168.2.3) with my wdtv box connected on OPT1 (192.168.3.231).

it seems all good and fine.
but after 15 minutes or sometimes 20, sometimes 25 and on last best try 28 mins, wooosh on screen a message "wdtv box looses mediaserver".

in pfsense log i can find some lines with:

gmpproxy: Warn: MRT_DEL_MFC; Errno(49): Can't assign requested address
&
igmpproxy: Warn: unknown Mode in V3 report (673189920)
&
gmpproxy: Warn: age_table_entry: SIOCGETSGCNT failing for (192.168.2.1 239.255.255.250); Errno(49): Can't assign requested address

I dont know if these lines are responsible for loosing media server on the wdtv live hub.

My Question now: do i had setup igmp proxy right? (above listing)
Is this igmp proxy not for watching media streams (films)?

anyone with experience out there who got it workig or has a solution for this scenario?

thank you.
