I have a gateway machine with 3 ethernet cards: re0 -> wan re1 -> lan re2 -> tv The tv interface connects to my isp's IPTV network where multicast udp and igmp packets come and go. In order for my computers and tvs to get the IPTV stream, i use an HTTP to UDP proxy (udpxy). This little application takes HTTP requests in the form of: http://udpxy-server:port/udp/CHANNEL_IP:CHANNEL_PORT from lan clients and registers to these multicast streams on the tv interface. However, the problem appears when i simply enable pf. With no rule in pf.conf, running /etc/rc.d/pf start simply makes udpxy to stop working throwing: read_buf: read: Resource temporary unavailable After spending lots of hours figuring this out, i disabled pf and everything suddenly worked. Using ipfilter, the problem is totally gone. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
