I have a Linux gateway (Redhat 7.2), and found, that I can chat with MSN Messenger, but the linux box doesn't allow to do voice conversation...:-(
I use iptables with the following settings:
Are you behind a firewall or NAT router? This can be problem with MSN as voice conversations and file transfers usually dont work if you are behind NAT or a firewall. You need to enable both UDP and TCP incoming/outgoing connections from the correct ports (6901 i think) i am not sure on the syntax though.
To enable voice communications in MSN Messenger , make sure that outgoing TCP connections from port 6901 are enabled.
Also enable UDP packets where either the source or the destination port is 6901.
iptables -A FORWARD -p tcp --dport 6901 -j ACCEPT
iptables -A FORWARD -p udp --sport 6901 -j ACCEPT
iptables -A FORWARD -p udp --dport 6901 -j ACCEPT
Also Masquerade this port,
iptables -t nat -A POSTROUTING -p tcp --dport 6901 -o eth1 -j MASQUERADE
This is all to open voice for MSN Messenger,
your posted iptables lines are enough for these rules, did you posted your complete rules?
What the commands
iptables -t nat -L
and
iptables -L
showing?
Just to chuck my bit in I have exactly the same problem, and was losing my sanity over the weekend trying to get voice to work. I am going to give this a go, if i have success I'll post back, if any one else has success would they let me know, please....
