IPNAT and Icecast

[Tam S Pham <pham@kelvin.mee.ucsb.edu>]

Hello,

I have IPF/NAT environment.  I'm running Icecast Streaming Server on one of my 
private LAN OpenBSD box and I want to be able to broadcast it outside of my 
private LAN (i.e., Internet).  Obviously I'm not able to.  Below are my 
ipf.rules and ipnat.rules files from my IPF/NAT gateway.  Any suggestion would 
be greatly appreciated.

/etc/ipf.rules

pass in from any to any
pass out from any to any


/etc/ipnat.rules

#Lengend: Valid_IP = IP connected to the internet.
#	192.168.1.12=Icecast server
 
map xl0 192.168.1.0/24 -> Valid_IP/32 portmap tcp/udp 5000:60000
map xl0 192.168.1.0/24 -> Valid_IP/32 proxy port ftp ftp/tcp
map xl0 192.168.1.0/24 -> Valid_IP/32

rdr xl0 Valid_IP/32 port 8000 -> 192.168.1.12 port 8000
