      Distributed Firewall supports ALG (Application Level Gateway) for the following protocols: TFTP, FTP, ORACLE TNS, MS-RPC, and SUN-RPC.

      Edge supports ALG for FTP, TFTP, and SNMP_BASIC.

      Note: VMs that are migrated from 6.1.5 to 6.2.3 do not have support for TFTP ALG. To enable TFTP ALG support after migrating, add and remove the VM from the exclusion list or restart the VM. A new 6.2.3 filter is created, with support for TFTP ALG.

    3. Type the port number and click OK.

    In order to protect your network from ACK or SYN floods, you can set Service to TCP-all_ports or UDP-all_ports and set Action to Block for the default rule. For information on modifying the default rule, see Edit the Default Distributed Firewall Rule.
