NAT Aware VRF on cisco7600
I am trying to find out wich feature set supports NAT on a VRF for the 7606 chassis with supervisor module WS-SUP720-3BXL.
thanx
Hi,
Using FWSM is definitely an alternate where you dedicate an single instance of vFW to perform NAT for a particular VRF. If this is not acceptable to you, you may consider other platforms like 7200 that can deliver a solution today for this.
However, for all potential roadmap related discussion I would recommend you to directly get in touch with your account team since this forum may not be the right place to discuss such things.
Cheers,

Hi to all, i'm trying to configure nat between vrf.I have a network with multiple vrf and a common vrf where there are some service shared among them.
I've ip overlapping issue, so i'm trying to use nat aware vrf.
The shared service is on a vrf also.
I use route-target import and export to import route between vrf.I've seen nat is working between VRF and global routing, but not between different VRF that already are able to comunicate.
This is my configuration :
ip vrf proxy
rd 500:500
route-target export 500:500
route-target export 501:501
route-target import 500:500
route-target import 401:401

as you can see i export route from vrf upa and upa-tv as RT 401:401 ,and import it in proxy vrf, and in the same way i export route from proxy vrf as RT 501:501 and import it into upa and upa-tv.
network 10.4.1.0/24 exist in both vrf upa and upa-tv.So i 'd like to nat one of them with another ip address (i tried to use a static translation to be able to reach the same ip address in both vrf). I make some test, and it seems to work when i make a nat from vrf to global, but not work when nat is between vrf (is this supported ?).I tried with NVI and with classic nat command:

tried also with
ip nat inside source static 10.4.1.12 169.254.99.12 vrf upa
but it didn't work...
any suggestion ?
any help will be appreciated
MaxHi Mohammed, now all works well.
I understand my error, basically when i tried to ping, i pinged a router on my
own vrf, because i imported the network, so the packet didn't came across
interfaces and nat was not in place.Now i tried static host and network
natting and dymanic natting and all works well.
here there is a complete working configuration

Many thanks for the help, now all works well and i understand the way to
configure it. -
Is it possible to do address translation between VRFs? I see NAT is possible from VRF to global, but haven't find any info about possibility to NAT between VRFs. Is it possible ?
Please refer the following link for more information on NAT Integration with MPLS VPNs.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122newft/122t/122t13/ftnatvpn.pdf -
Folks,
Can anyone verify as to why Syslog messages from an interface in a VRF instance not being transmitted, but when I remove the VRF and do the same with "plain" IP, it works.
Also while configuring Syslog server I cannot specify the VRF if the Management station is in a VRF.
Any ideas about it ??
Thanks
~sultanHello Sanjeeva,
That helped me get out of this problem I am stabbing since a last few days and I really thank you guys for this...
So I guess I will have to wait for the next release... :-)
Thank you too Harold.

I am trying to get NAT working on a Cisco 2801 with HWIC-4ESW.
I have a 2801 that had a failed Fe0/1 port. The Fe0/1 port was used to give sub-interface Fe0/0.200 access to internet. We installed a HWIC-4ESW into the 2801. I have successfully moved the sub-interfaces ( 0/0.1 , 0/0.100 , and 0/0.200 ) from the Fe0/0 to the HWIC-4ESW. I have reconfigured the Fe0/0 to connect to my ISP. However, I cannot get traffic from vlan200 to pass to the internet over Fe0/0. I have a guest wireless network set for vlan 200. Clients get an IP address in the appropriate range (192.168.200.0), but they cannot get to the internet. Below I have included the results of "sh ip int brief" and some of the "sh run". I think that it is something simple, but I canot get it working.
Help would be appreciated.

I would like to start using NAT on our PE nodes but I cannot get it working. I have a lab setup with two vrf's terminating on the same node. In the lab I would like to NAT an address(Arguments sake a server) in the one VRF (Customer-C) to a unique address so that the other VRF (Customer-B) is able to reach this server via this address. I have the NAT statements in place and if I do a sh ip nat trans the nat shows up as active but if a I do a sh ip nat trans vrf there is nothing.
These are the commands I used:
ip nat pool inside1 60.60.60.1 60.60.60.254 netmask 255.255.255.0
ip nat inside source list test-nat pool inside1 vrf Customer-C
ip nat outside source static 50.50.50.1 60.60.60.1
ip access-list extended test-nat
permit ip 50.50.50.0 0.0.0.255 any
What am I doing wrong ? Any help would be appreciated.I am not sure how you are attempting to make Customer B communicate with Customer C if you are using separate VRFs for them. There will not be any interaction between them unless they both tegether form a VPN with their routes contained in a single VRF. Once this is done, you can try to troubleshoot the NAT configuration.

We can reach internet ip address from GigabitEthernet0/1/1/1. ServiceInfra interface and all serviceapp interfaces are up. Need help check this issue because we will do migration by the end of this week.
Thanks in advance and really appreciate your help.@Nicolas:
The way I change the vrf is by assign different port to each InsideOfficeNat, InsideWifiNat and InsideUserNat. When testing each vrf I move the physical connection. When I was experienced problem using InsideOfficeNat, the Inside to Outside Packet result in "show cgn nat44 nat1 outside-translation protocol udp outside-vrf default outside-address 100.62.16.126 port start 1 end 65535" is counting but not for Outside to Inside Packets. And same symptom with InsideWifiNat.
@Nicolas and Harold:
Actually right now all vrf-inside successful doing translation and we also change the CGN configuration without vrf on physical inside interface. But we found the browsing experiences are very slow and some contents were not loaded successfully. Any idea what happened?
Here the configuration:

hi, i want to implement vrf aware nat and i want to create a single pool for all vrfs. when the traffic returns is there a way the ios identify which vrf the IP belongs to so i dont have to specify the pool for each vpn whit static routes? Thanks ahead- asanes
Hi,
As I understand you want to integrate NAT with MPLS based VPNs.
Follwing Cisco link should help:

Hi
In an Enterprise Network we are using CAT6500 SUP720/MSFC3B with VRF Lite.
According to the Software Advisor VRF aware NAT is not supported on the 6k. But I think with the MPLS image it should be supported.
My question: Is it supported and if yes whats the recommended image if i just want to have vrf-lite with vrf aware NAT - no MPLS
cheers
patrickIF you have a FWSM then you should be good to go for the VRF-Aware NAT. I am not aware of NAT being performed natively on the SUP.

2800s, AIM-VPN-SSL2, vrf aware IPSEC, high CPU low throughput
We have a couple of new 2821s deployed across a fibre link and they were originally running 12.4 (non T) versions using software encryption. We would get around 8Mb/s throughput. Upgrading to T to use the installed AIM cards we now see the AIM cards in use (show cry isakmp sa det shows then engine as aim vpn), but we still get the same throughput and high CPU. allowing CEF on the interface doubles throughput but with the same high CPU. The only process I can see going high is IP Input. Is this because of vrf aware ipsec - or any other suggestions?
Hi Nick,
I am having the same issue. We have a 2851 as a IPSEC VPN headend with an AIM VPN module but we are seeing high CPU usage(80%) with just 4-5mbps worth of traffic. I have an idea that I might have a NAT issue.
We are currently running, NAT, ZFW, and IPSEC site 2 site VPN on the router.
When I look at my ZONE firewall policy-map output it is showing all of my VPN traffic as process switched.
Inspect
Packet inspection statistics [process switch:fast switch]
tcp packets: [14809800:0]
udp packets: [145107:0]
icmp packets: [20937:12]
I have disabled the ZFW and still see high cpu although it is a little lower.
Packets are not fragmented, CEF and fast switching looks to be enabled. I am using a route-map for my nonats. That is the only thing I can think of now.
I have tried IOS 12.4(20)T3,4 and 12.4(15)T9. Same results.
Anyone have some ideas? -
NAT Public Addresses to diffrent VRFs
Hi,
We have a /28 on the outside and want to assign seperate IP addresses with NAT to seperate VRFS, for example:
130.140.131.78 -> NAT -> vrf A -> 192.168.1.1
130.140.131.79 -> NAT -> vrf B -> 192.168.1.1
on so on and so forth....
Is this possible ? I have tried several option but no luck/wisdom so far.
Gr. Gilles.
P.S. Platform are routers 29xx and 39xxHi,
what options have you tried already ?
I think that vrf-aware static nat will do the job, something like:
ip nat inside source static 192.168.1.1 130.140.131.78 vrf A

Hi,
i´ve try to get an dynamic VTI with VRF Aware on the HUB Router and PKI for Authentication.
My Problem is, that Phase1 works fine, but Phase2 doesn´t came up.
debug crypto isakmp

Have any one of you a working configuration with this parameters or an idea, what i can do ?
The Virtual-Template Interface ist up/down and no interface virtual-acces was created.

NAT is not working for VRF partially
Hello!
I have a diagram like this:
VRF_A and VRF_B have overlapping addressing plans from series 192.168.x.x.
As routing protocol in both of VRFs adopted RIP (I tried all, but effect much the same).
The closest to PE1 network is 172.16.0.0/24.
PE1:
ip vrf VRF_A rd 65001:1 route-target export 65001:1 route-target import 65001:1ip vrf VRF_B rd 65001:2 route-target export 65001:2 route-target import 65001:2ip nat inside source list 10 interface FastEthernet0/0 vrf VRF_A overloadip nat inside source list 10 interface FastEthernet0/0 vrf VRF_B overloadip route vrf VRF_A 0.0.0.0 0.0.0.0 FastEthernet0/0 172.16.0.1 globalip route vrf VRF_B 0.0.0.0 0.0.0.0 FastEthernet0/0 172.16.0.1 globalinterface FastEthernet0/0 ip address 172.16.0.24 255.255.255.0 ip nat outside duplex fullinterface FastEthernet1/0 ip vrf forwarding VRF_A ip address 192.168.0.2 255.255.255.0 ip nat inside duplex full
interface FastEthernet4/0 ip vrf forwarding VRF_B ip address 192.168.0.2 255.255.255.0 ip nat inside duplex full
When I try ti ping 172.16.0.1 from CE11, CE21 and from VRF_A and VRF_B on PE1 - all if fine! NAT is performed and ping is OK.
But when I tried to ping from others (PE2 and CE21 and CE22) NAT is not performed, I see 192.168.x.x at Internet Router and ping is failled.
I'm in stupor. What could it be??? And how to avoid this situation? Are there "exits"?
I forgot to mention that there is a full connectivity inside both of VRFs. Routing protocols and redistribution work fine.
Kind regard,
