These two packages with the same router ip address mixes each other, then IPTV server stops sending IPTV igmp channel packages. So we need to change igmp router ip address on MA5616 with an other ip address. We use ip address as igmp router ip address on MA5616. This ip address is a randomly chosen ip address, because it is never used as gateway on any dsl modem.
