MSN messenger Audio connection blocked by Iptable
Posted on 2004-05-02
I have a intranet eastablied, geteway is running iptable as a NAT server, inside my intranet, 192.168.1.2 address is used. everything works fine until I try to use my MSN Messenger audio to chat with my friends, connection cannot be eastablied at all. I wonder if MSN has some "call back" port needs to be confured, or how can I have MSN audio connection?
My rule set for Iptables is pretty easy:
iptables -t nat -F
iptables -t nat -A POSTROUTING -s 192.168.1.2 -j MASQUERADE
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -A FORWARD -s 192.168.1.2 -j ACCEPT
iptables -A FORWARD -d 192.168.1.2 -j ACCEPT
Do I have to add more rules ?
