Hi,
I read some document about allowing MSN voice using Iptables and setup the following commented ruleset in my firewall rules startup file. I did it manually too but didn't help.
Could you please take a look at the ruleset below and advice me the correct order OR ruleset to allow MSN voice chat ?
I would really appreciate your reply.
Thanks
Rajeev
