Is my astro gateway hacked

i am getting lot of IPS attacks recently what worried me most is 4th root return

i have no server running just 2 computers behind astaro

7 basics rules

1.ftp : internal (Network) to any
2 web browser : internal (Network) to any
3 irc : internal (Network) to any
4 internal ping : Internal (Network) to Internal (Address)
5 DNS internal (Network) to any
6 ubuntu key server : internal (Network) to ubuntu key server
7 block all incoming network

also i disable external ping response i created a rule for internal ping

no remote login
no ssh everything disabled.

also admin login through internal network only where i have just 3 family pc to connect no dhcp no vpn

on country blocking i block lot of countries web proxy enable

Intrusion Prevention is active with 8895 of 11204 patterns enable block everything expect servers as i am not running anyone also enable extra warnings

ips on (internal network)

antivirus enable

antispyware enable
