Tvheadend

Dear community,

I have the following setup:

Fritzbox 192.168.0.1/255 -> Google Wifi DHCP 192.168.178.1/255 -> Synology 192.168.178.107 running TVHeadend
I configured 4 IP Adresses in the Synology, eth0:0 192.168.178.130, eth0:1 192.168.178.131, eth0:2 192.168.178.132 an eth0:3 191.168.178.133
Made up the TV headend configuration with the --satip_xml argument to http://192.168.0.254:49000/satipdesc.xml
All fine so far, I get 4 adapters in TVHeadend but: only 32 Muxes, 0 Services and scanning of all muxes failed.

I this this has something to do with the two IP areas, what do you think? I also cant ping any of the 4 "new" IPs...

Thanks for your help
