ASUS RT-N66U IPTV connected to LAN port + udpxy

Hello!
I have 2 ethernet-cable from my povider. One with internet (I connected it to WAN port on router) and other - with IPTV (I connected it to LAN4 port).
I can watch IpTv on PC with VLC-player using udp-links (like udp://@233.26.198.130:5000). But I cannot setup udpxy to watch iptv via udpxy. How can I setup udpxy to work with this configuration?
