@becs Thanks for the offer to solve the IGMP issue via direct support. I already have been in contact with support more than one year ago using version 2.6.

Hello,

German IPTV (Entertain TV, MR401/201) still not working at all with this SwOS version (CSS326). No IGMP v3.

Robert

I used SwOS 2.6 without any problems until I tried to operate an IPTV box MR401 (Deutsche Telekom, Entertain TV) on my CSS326 in parallel to one IPTV box directly connected to my router. IPTV box connected to CSS326 did not work (insufficient network connection was reported). Turning on IGMP snoopin...
