CPF with router

To prevent a lot of warnings about IP Acess Denied and ICMP messages to/from my internet provider I create some rules:

  1. Allow IP Out (Source: Any / Destination: RANGE -
  2. Allow IP In (Source: RANGE - / Destination: Any)
  3. Allow ICMP In for Any Message (Source: Any / Destination: My Internal IP Address (invalid))
  4. 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.
