(Continued)
NAT (NAPT)
NAT operations such as IP Address replacement, Transport layer port number replacement, and checksum
generation done in hardware
Supports PPPoE Tunneling and IPv6 over IPv4 Tunneling at WAN Interface
Supports IPv4 only.
Layer 3/4 Filtering
Filtering based on IP Address (Dst and/or Src, supports both IPv4/IPv6)
Filtering based on TCP/UDP port number (supports TCP and ACK flag)
Filtering based on combinations of IP address and TCP port number in TCP connections for both IPv4 and IPv6.
Filtering based on ICMP Type
Filtering based on Protocol Type (Type field in Ethernet)
Supports PPPoE discovery stage /session stage filtering
Supports AH (Authentication Header) Type VPN packet filtering by Layer 3/4 information
Supports ESP (Encapsulating Security Payload) type VPN packets filtering by IP Address
Filtering can be applied independently per each port (LAN,D.M.Z., WAN)
Supports Max 64x2 (Inbound and Outbound) Filter Table Entries
Supports filter logging
Packet Prioritizing Function
Prioritization based on combination of IPv4 address and UDP port number
Prioritization based on combination of IPv4 address and ToS field
Prioritization based on combination of IPv4 address, ToS field and UDP port number
Prioritization based on combination of IPv6 address, Traffic Class and Flow Label
Supports QoS mapping ToS field
Note: The FEF supports only DIX type Ethernet Frames, and does not support IEEE802.1 LLC type frames and
IEEE802.1Q VLAN tagged frames (These frames, when received, will be sent to the host).
Achieving a full wire rate bi-directional throughput of 100 Mbps at 50 MHz operation.
