Hi all, I've trying to configure an OpenBSD box to allow PF to pass video-conference traffic through a NATed network without success.
I tried to setup the most basic configuration in order to find out where the problem could be. Last test I did, I configured an OpenBSD box with two network interfaces ($if_int and $if_ext) and PF enabled. NAT is done on $if_ext, and all the traffic is redirected from LAN to the videoconf PC. [VideoConf PC]----[OpenBSD box]-------------LAN 192.168.10.2/24 .10 172.22.1.200/16 -> When I try to call (using Netmeeting and other H.323 software) from the VideoconfPC to a PC, the other party answers and audio flows only in one direction: The PC in the LAN hears what I say, but nothing is heard in the VideoConf PC. <- When I try to call from the LAN to the VideoConf PC (using OBSD's external IP as address) Netmeeting says the other party is not responding. Tcpdump does not show any blocked packet and the rdr seems to work properly. As you can see bellow, my pf.conf is very simple: Any ideas? What do you think I've misconfigured? pf.conf ------------------------- # interfaces if_ext = "pcn0" if_int = "pcn1" videoconf = 192.168.10.2 nat log on $if_ext from $videoconf to any -> $if_ext rdr log on $if_ext -> $videoconf pass log all -------------------------- Thanks in advance, Fernando Alvarez
