To prevent a lot of warnings about IP Acess Denied and ICMP messages to/from my internet provider I create some rules:
- Allow IP Out (Source: Any / Destination: RANGE 188.8.131.52 - 184.108.40.206)
- Allow IP In (Source: RANGE 220.127.116.11 - 18.104.22.168 / Destination: Any)
- Allow ICMP In for Any Message (Source: Any / Destination: My Internal IP Address (invalid))
- Allow ICMP Out for Any Message (Source: My Internal IP Address (invalid) / Destination: Any)
Note: Router have a built-in firewall.
Am I insecure with this changes?
In addiction to default rules and rules above I have TCP/UDP rules to P2P works properly.
