Hi All,

Is there anyone ever try destination NAT in 7750 ? I cannot apply source prefix in router nat. When I try to apply the source-prefix there warning

*B:PE2-POC>config>router>nat>inside# dnat-only source-prefix-list "DNAT"
MINOR: BB #1012 The nat policy does not exist - default nat-policy not set

Here is my configuration in service NAT

*B:PE2-POC>config>service>nat# info
----------------------------------------------
nat-classifier "DNAT" create
entry 1 create
action dnat ip-address 172.100.100.1
match protocol tcp
dst-port-range start 22 end 22
exit
exit
exit
nat-policy "DNAT" create
alg
no ftp
exit
dnat
dnat-only router "Base" nat-group 2
exit
exit
nat-policy "default" create
exit
nat-policy "lsn-policy-vprn753293" create
pool "lsn-pool-vprn753293" router 753293
exit
nat-prefix-list "DNAT" application dnat-only-subscribers create
prefix 5.5.5.0/30
prefix 222.222.222.222/32
exit
----------------------------------------------

Cheers

Never tried it myself, but maybe because you're missing a default action for the NAT classifier?

Code: Select all

configure>service>nat
                     nat-classifier <name>
                     default-action {DNAT|forward} [ip-addr <ip-address>]

There's an example in the DNAT section of the 7750 SR MS-ISA Guide.

Hi,

Its because must be configured nat policy at inside nat router

*B:config>router>nat# info
----------------------------------------------
inside
nat-policy "default"
classic-lsn-max-subscriber-limit 2
dnat-only
source-prefix-list "DNAT-Prefix"
exit
exit

Anyone ever tried the NAT destination ? Because I alredy config like in the MS-ISA Guide but still failed. ?
