outbound network connectivity problems

You might also have a secure SMTP relay service running on-premises that you can use. If the ping gets a response when the network is not connected to the Firebox interface, some other host on the network uses an IP address that conflicts with the IP address of the Firebox interface. To learn more about the Traffic Monitor Dashboard, see Traffic Monitor. Check for a Valid IP Address. If this fails, attempt to ping a remote IP address, such as the DNS server for your ISP, or a public DNS server such as 8.8.8.8 or 4.2.2.2. If you are unable to ping the internal IP address of the Firebox, this could indicate a problem with the configuration on the Firebox, or a problem with your local network configuration or cabling. If the cable allows for a better connection, then the problem could lie in the wireless connection. Then, connect the same computer to the wired network and note any changes in performance. These services are used to maintain IP or domain reputation to minimize the possibility that third-party email providers will reject the message. The Edit Policy Properties dialog box appears. Create a firewall rule to allow outbound traffic and enable outbound filtering. ICMP ping isn't supported. In most cases, the default gateway must be the IP address of the internal Firebox interface that the local network connects to. The log message tells you which policy denied the traffic. The problem is, however, that the average home user likely doesn’t have the know-how to be able to configure it properly.

To identify the cause of Internet connection problems from computers on your local network, start with ping tests from a local computer on your network to the Firebox or a local server on your network. If the client computer uses DHCP to get an IP address, and the IP address and gateway assigned on the client do not match the DHCP server settings configured on the Firebox interface this network connects to, it is possible that a rogue DHCP server is on your network and assigned the unexpected IP address. This command sends several packets to the address you specify.

Check that the LAN subnet mask is correct ( Interfaces > LAN) Using an incorrect subnet mask, such as /32, will prevent other hosts in LAN from finding the LAN to use as a gateway and vice versa. It can be useful to enable logging of allowed packets for a policy such as Ping while you troubleshoot network connectivity issues.
