Specify NIC for m3u entries

Kodi 16.1+dfsg1-2 is running in Ubuntu 16.10 x64. I have two nics in my computer, one for network and the other for IPTV.
When I provide the .m3u in format mentioned in wiki, that doesn’t work, presumably because it sends requests via the first nic.

How can I set up IPTVSimpleClient such that it would direct requests to second nic?
