Security ACLs can filter TCP and UDP packets by source and destination IP
address, precedence, and TOS level. You can apply a TCP ACL to
established TCP sessions only, not to new TCP sessions. In addition,
security ACLs for TCP and UDP can filter packets according to a source
port on the source IP address and/or a destination port on the destination
IP address, if you specify a port number and an operator in the ACE. (For
a list of TCP and UDP port numbers, see
www.iana.org/assignments/port-numbers.)
The operator indicates whether to filter packets arriving from or destined
for a port whose number is equal to (eq), greater than (gt), less than (lt),
not equal to (neq), or in a range that includes (range) the specified port.
To specify a range of TCP or UDP ports, you enter the beginning and
ending port numbers.
The CLI does not accept port names in ACLs. To filter on ports by name,
you must use 3Com Wireless Switch Manager. For more information, see
the Wireless Switch Manager Reference
Setting a TCP ACL
The following command filters TCP packets:
set security acl ip acl-name {permit [cos cos] | deny}
tcp {source-ip-addr mask | any} [operator port [port2]]
{destination-ip-addr mask | any [operator port [port2]]}
[[precedence precedence] [tos tos] | [dscp codepoint]]
[established] [before editbuffer-index | modify
editbuffer-index] [hits]
