I'm trying to build up my firewall configuration.
And then, I've tried to put a rule, in my iptables configuration, for GAIM.
iptables -t filter -A INPUT -p tcp --sport 1853 -j ACCEPT
but it doesn't work. When I run GAIM icq behave just fine but with msn protocol it is not the same.
Some one knows what is this ?
Thanks a lot.
ps. I also put as the first line iptables -t filter -P INPUT DROP.
