Kmod-ipt-nathelper-rtsp on 22.03.0

Hi. I was using kmod-ipt-nathelper-rtsp in order to make work my IPTV provider VOD (setting net.netfilter.nf_conntrack_helper = 1). I've updated to 22.03 and VOD is not working anymore. I suppose that is related with change to firewall4 and nftables.
Any solution or alternative? Thanks
