Step Description Command Keys
2 Create a pool of IP addresses and/or
TCP/UDP ports with a specific name
(optionally).
esr(config-snat)# pool <NAME> <NAME> – NAT addresses pool
name, set by the string of up to
31 characters.
3 Set the range of IP addresses which will
replace a source IP address.
esr(config-snat-pool)# ip address-
range <IP>[-<ENDIP>]
<IP> – IP address of the
beginning of the range, defined
as AAA.BBB.CCC.DDD where
each part takes values of
[0..255];
<ENDIP> – IP address of the
end of the range, defined as
AAA.BBB.CCC.DDD where each
part takes values of [0..255]. If
IP address of the end of the
range is not specified, only IP
address of the beginning of the
range is used as IP address for
translation.
4 Specify the range of external TCP/UDP
ports which will replace a source TCP/
UDP port.
esr(config-snat-pool)# ip port-
range <PORT>[-<ENDPORT>]
<PORT> – TCP/UDP port of the
beginning of range, takes
values of [1..65535];
<ENDPORT> – TCP/UDP port of
the end of range, takes values
of [1..65535]. If TCP/UDP port
of the end of the range is not
specified, only TCP/UDP port of
the beginning of the range is
used as TCP/UDP port for
translation.
5 Set the internal TCP/UDP port which
will replace a source TCP/UDP port.
esr(config-snat-pool)# ip port
<PORT>
<PORT> – TCP/UDP port, takes
values of [1..65535].
6 Enable NAT persistent functions. esr(config-snat-pool)# persistent
7 Create a rule group with a specific
name.
esr(config-snat)# ruleset <NAME> <NAME> – rule group name, set
by the string of up to 31
characters.
8 Specify VRF instance, in which the
given rule group will operate
(optionally).
esr(config-snat-ruleset)# ip vrf
forwarding <VRF>
<VRF> – VRF name, set by the
string of up to 31 characters.
