Configure Traffic Permits and Fixups
Use caution when you configure traffic permits and fixups. We recommend
that you use the default values.
To configure traffic permits or packet fixups, follow these steps.
1. Click the Advanced tab.
2. In the Traffic Permits table, choose one of these options for unsupported
incoming and outgoing packets:
• Pass-Through—Permit the packets to pass across the NAT boundary.
• Blocked—Drop the packets.
3. In the Fix-up Packets area, check or clear the checkboxes to enable or
disable protocol fixups for ARP and ICMP.
By default, fixups are enabled for both ARP and ICMP.
