Chapter 4 Configuring Network Object NAT

 

 

Monitoring Network Object NAT

 

Detailed Steps

 

 

 

 

 

Command

Purpose

 

 

xlate per-session {permit deny} {tcp udp}

Creates a permit or deny rule. This rule is placed above the default

source_ip [operator src_port] destination_ip

rules, but below any other manually-created rules. Be sure to

operator dest_port

create your rules in the order you want them applied.

 

Example:

For the source and destination IP addresses, you can configure the

following:

ciscoasa(config)# xlate per-session deny tcp any4

•

host ip_address—Specifies an IPv4 host address.

209.165.201.3 eq 1720

 

• ip_address mask—Specifies an IPv4 network address and

 

 

subnet mask.

 

• ipv6-address/prefix-length—Specifies an IPv6 host or

 

 

network address and prefix.

 

• any4 and any6—any4specifies only IPv4 traffic; and any6

 

 

specifies any6 traffic.

 

The operator matches the port numbers used by the source or

 

destination. The permitted operators are as follows:

 

•

lt—less than

 

•

gt—greater than

 

•

eq—equal to

 

•

neq—not equal to

 

• range—an inclusive range of values. When you use this

 

 

operator, specify two port numbers, for example:

 

 

range 100 200

 

 

 

 

Examples

The following example creates a deny rule for H.323 traffic, so that it uses multi-session PAT:

ciscoasa(config)# xlate per-session deny tcp any4 209.165.201.7 eq 1720 ciscoasa(config)# xlate per-session deny udp any4 209.165.201.7 range 1718 1719

Monitoring Network Object NAT

To monitor object NAT, enter one of the following commands:

Command

Purpose

 

 

 

 

show

nat

 

Shows NAT statistics, including hits for each NAT rule.

 

 

 

 

show

nat

pool

Shows NAT pool statistics, including the addresses and ports allocated,

 

 

 

and how many times they were allocated.
