–
TCP — Transmission Control Protocol (TCP). Enables two hosts to communicate and exchange data
streams. TCP guarantees packet delivery, and guarantees packets are transmitted and received in the
order they are sent.
–
EGP — Exterior Gateway Protocol (EGP). Permits the exchange of routing information between two
neighboring gateway hosts in an autonomous systems network.
–
IGP — Interior Gateway Protocol (IGP). Permits the exchange of routing information between gateways
in an autonomous network.
–
UDP — User Datagram Protocol (UDP). Communication protocol that transmits packets but does not
guarantee their delivery.
–
HMP — Host Mapping Protocol (HMP). Collects network information from various networks hosts. HMP
monitors hosts spread over the internet as well as hosts in a single network.
–
RDP — Remote Desktop Protocol (RDP). Allows clients to communicate with the Terminal Server over
the network.
–
IDPR — Matches the packet to the Inter-Domain Policy Routing (IDPR) protocol.
–
IDRP— Matches the packet to the Inter-Domain Routing Protocol (IDRP).
–
RSVP — Matches the packet to the ReSerVation Protocol (RSVP).
–
AH — Authentication Header (AH). Provides source host authentication and data integrity.
–
EIGRP — Enhanced Interior Gateway Routing Protocol (EIGRP). Provides fast convergence, support for
variable-length subnet mask, and supports multiple network layer protocols.
–
OSPF — The Open Shortest Path First (OSPF) protocol is a link-state, hierarchical interior gateway
protocol (IGP) for network routing Layer Two (2) Tunneling Protocol, an extension to the PPP protocol
that enables ISPs to operate Virtual Private Networks (VPNs).
–
IPIP — IP over IP (IPIP). Encapsulates IP packets to create tunnels between two routers. This ensures
that IPIP tunnel appears as a single interface, rather than several separate interfaces. IPIP enables
tunnel intranets to access the internet, and provides an alternative to source routing.
–
PIM — Matches the packet to Protocol Independent Multicast (PIM).
–
L2TP— Matches the packet to Layer 2 Internet Protocol (L2IP).
–
ISIS — Intermediate System - Intermediate System (ISIS). Distributes IP routing information throughout
a single Autonomous System in IP networks.
–
Any — Matches the protocol to any protocol.
•
Source Port — Defines the TCP/UDP source port to which the ACE is matched. This field is active only if
800/6-TCP or 800/17-UDP are selected in the Select from List drop-down menu. The possible field range is 0
- 65535.
•
Destination Port — Defines the TCP/UDP destination port. This field is active only if 800/6-TCP or 800/17-
UDP are selected in the Select from List drop-down menu. The possible field range is 0 - 65535.

Source
–
IP Address — Matches the source port IP address from which packets are addressed to the ACE.
–
Mask — Defines the source IP address wildcard mask. Wildcard masks specify which bits are used and
which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard
of 0.0.0.0 indicates that all the bits are important. For example, if the source IP address 149.36.184.198
and the wildcard mask is 255.36.184.00, the first eight bits of the IP address are ignored, while the last
eight bits are used.
