Protocol Filtering
IP routing support provides the ability to process
TCP/IP
IP Routing —
frames at the network layer for routing. IP routing support includes the
Routing Information Protocol (RIP) that allows the exchange of routing
information on a TCP/IP network. The MicroMMAC receives and
broadcasts RIP messages to adjacent routers and workstations.
Internet Packet Exchange (IPX) routing support
IPX Routing —
provides the ability to process Novell proprietary frames at the network
layer for routing. IPX routing support includes both Routing Information
Protocol (RIP) and Service Advertising Protocol (SAP) that allows the
exchange of routing information on a Novell NetWare network. The SAP
provides routers and servers containing SAP agents with a means of
exchanging internetwork service information.

PROTOCOL FILTERING
Filtering enables efficient usage of network resources and provides
security for the network and hosts.
IP Internet Firewall
The MicroMMAC supports IP Internet Firewall filtering to prevent
unauthorized access to your system and network resources from the
Internet or a corporate Intranet. Security can be configured to permit or
deny IP traffic. The security is established by configuring IP access filters,
which are based on source IP address, source mask, destination IP
address, destination mask, protocol type, and application port identifiers
for both the Transmission Control Protocol (TCP) and User Datagram
Protocol (UDP). These IP access filters allow individual IP source and
destination pair filtering as well as IP address ranges and wild carding to
match any IP address. These Firewall filters can be defined to allow
inbound only, outbound only, or bi-directional IP communication up to
the UDP and TCP application port level. Firewall access filters can
establish a powerful IP security barrier.
The MicroMMAC supports the IP Access Control (from the ctip-mib)
Internet Firewall Filter.
