Hello,
After days of intense attacks I have turned on all ips rules to verify and lock all traffic.

All working well except the apt-get out traffic from my Ubuntu desktop,
The connections using apt-get go in time out and if i disable ips all works.

Which are the ips rules to allow aptget traffic??
Thanks.
