NAT WITH FLEXVPN
Hello
Please can someone tell me how NAT with flexvpn?
I have a HUB to spoke and spoke to talk configuration with virtual-templates.
When I configure NAT and do a traceroute to google the first hop ip address is the HUB router.
but it must go directly to the internet.
Thanks in advance,
Topcu, M
Take a look at the difference between the defined itinerary and accept the traffic.
You're forcing the default routes... bad idea unless controlled :-)
Start by removing the "any" declaration of access lists using road together.

Static NAT with the road map for excluding the VPN
We have problems of access to certain IPs NATted static via a VPN. After some research, we have learned that you have to exclude traffic destined for the VPN to the static NAT using a road map. So we did this:
10.1.1.x is the VPN IP pool.
access-list 130 refuse ip 192.168.1.0 0.0.0.255 10.1.1.0 0.0.0.255
access-list 130 allow ip 192.168.1.0 0.0.0.255 anysheep allowed 10 route map
corresponds to the IP 130IP nat inside source static 192.168.1.5 1.1.1.1 sheep map route
Above worked to fix the VPN but the IP 192.168.1.5 is no longer publicly available via 1.1.1.1. What seems to happen, is that the static NAT is not really work and this IP address is NATted with the IP of PAT.
Any ideas on how to get this to work?
Thank you
DiegoHello
The following example details exactly your case:
http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080094634.shtml
Try to replace the 192.168.1.0 subnet by the host address.
It should work

Now,.
I want nat by looking at the destination address.
example if destination is A nat for x pool network, and if the destination is something different then nat to the pool of y.
IOS supports natting with ACLs and road maps.
but as stated in the order reference specifying acl is valid only for the nat 0.
So how can I nat based on destination address.
is it possible with pix?
If so, how?
Thanks in advance
You can not do conditional NAT based on destination on the Pix address. The only way to achieve this would be to have several interfaces with itineraries that would send traffic for each interface, NAT them as appropriate.

For the poster who will say "Google is your friend", no it is not, or I wouldn't be here.
I tried for a while now to solve the only problem I have with Snow Leopard Server.
MySql has fallen lion and, apparently, no one knows how to use postgrl so I installed MySql and plundered with her for a few hours to get this working. There were various other issues with Lion. Finally, I went to Yosemite. Hey Apple, where is the GUI? Then at el Capitan and finally tried Sierra (no server app at all yet).
For me, each 'step-up' taking things and running weaker than the last.
Welcome to Snow Leopard. I'll stick with it for a while to come.
The only problem I have with Snow Leopard, it's that when it restarts, the NAT will not start upward. Other than that, it does a magnificent job to maintain my home network. I searched high and low for an answer without success. A few posters who have addressed this problem specifically here never got a response.
As this seems to be about three years or more, since this question was asked and it seems that some have migrated to the SLS, I was wondering if anyone has found a solution.
As it is now, as soon as there is a need to reboot, I just disable the NAT service, restart and turn it back on. In the case of a failure of current (longer than the inverter can maintain) or just a random crash, I have to kill the firewall and NAT then the configuration of the gateway of new service that requires fixing the various omissions and errors and I'm good to go again.
Any help would be greatly appreciated.
You have posted in the forum of Snow Leopard Client. I ask that to move this post. In the meantime, you can see the various forums about this trick:

Strict NAT with a BEFSR41 router
So I play frequently on my xbox 360 and I like to browse my computer when I'm waiting for a match. With my old router, same brand and model, all I had to do was do port forwarding with the ports recommended on xbox.com and enable upnp and I had no problems to connect to games, joining friend games or assembling them mine.
So when I got my replacement router I have activated the same options as before but kept getting the strict NAT message when I start a game and none of my friends could join my game and I couldn't join them. So I enabled the DMZ and clone the MAC address of xbox 360. He got rid of the NAT strict message but I noticed a significant drop in the speed of the internet, yet none of my friend could join my game and I couldn't reach them.
So I had to unplug the router and connect the xbox directly on the modem I have while waiting for the replacement router and I could do all the things as before. So it leads me to believe that there is a problem with the router. I have a linksys BEFSR41 v. 4.3 router and modem motorola with a DSL connection.
Any advice or ideas would be greatly appreciated.
Yes, you are right that if the modem acts as a router, it should be filled if you want to connect to another router... If your modem is full you will not get the internet light on your modem (it will remain off)...
Once you configure the modem in Bridge mode full you must configure the type of internet connection of your router in PPPoE and enter the correct user name and password provided by your Internet Service Providor (ISP)... Once done, click on save settings...
Click the status tab and search for an IP address, if you get 0.0.0.0 for the IP address click on the Connect button and weait... Power Cycle your modem and your roputer for a minute and see if you can go online... Once you are online, you can make the settings as shown in the previous post for your X - Box and it should connect...

Hello friends
I m noob with firewall and I create a VPN site-to-site with a customer with the tracking information:
My site:
10.204.x.x/24
10.69.0.0/24
others
Customer site:
172.30.20.0/24
But my site 10.69.0.0 network is an internal network of the client, that they asked me to do a NAT when the network 10.69.0.0 will 172.30.20.0 them must go out with the IP 172.30.100.0.
Anyone know what can make it work configurations?
Thank you
Marcio,
You can use a political static NAT:
network of the LAN object - 10.69.0.0
subnet 10.69.0.0 255.255.x.x
network object obj - 172.30.100.0_nat
172.30.100.0 subnet 255.255.255.0
network object obj - 172.30.20.0
172.30.20.0 subnet 255.255.255.0
NAT (inside, outside) source static LAN - 10.69.0.0 obj - 172.30.100.0_nat destination static obj - 172.30.20.0 obj - 172.30.20.0

I have a pretty well configured WRVS4400N with the DMZ enabled by default. My ISP has contacted me and said that my private IP are routed to the Internet. I can't make a sense that since everything seems to be upward and the work. I thought that the Internet would not work because private IP addresses are supposed to be deleted as soon as they are on the Internet. Any ideas?
The firmware version 2.0.2.1
Yes, don't know what they mean your private is slotting of. It is possible for private routing... IP addresses but this happens very rarely when someone messes up on the side of the ISP... As long as the router works in "Gateway" mode, you'll be THAT NAT would have
Personally, I think nothing of what was told to you (at this time), unless he is once again facing upwards.

Wierd NAT with AnyConnect client behavior
Hello
I have a problem with our customers AnyConnect not being able to access a particular resource that exists on a 3rd party VPN.
Both the AnyConnect customers & 3rd Party Site to Site VPN terminate on the external Interface of the ASA.
There is a NAT configuration between the 3rd party and our ASA network so that we share the 192.168.40.0/24 subnet. 25 first is for 3rd party guests & the second 25 is for our guests.
We are trying to access a service on 192.168.40.10
The NAT rule that I have in place to achieve this goal is
Source = sub-VPN-network Dest = 192.168.40.0/25 = any Service
XLate Source = 192.168.40.129 (PAT) Dest = XLateService Original XLate = Original
With the NAT rule like this, the Web page only FACT NOT work. We get a Timeout of SYN, and looking at the logs, the AnyConnect client source address does not PAT would have to 192.168.40.129
BUT...
If I change the NAT rule for this...
Source = sub-VPN-network Dest = 192.168.40.0/25 = any Service
XLate Source = 192.168.40.129 (PAT) XLate Dest = 192.168.40.10 XLateService = Original
THIS WORKS! The source address does get PAT'd from 192.168.40.129.
BUT... the problem is now, that if the AnyConnect client attempts to access any other IP in 192.168.40.0/25, the destination address gets changed all the time at 192.168.40.10.
I am new to ASA 8.3, so I was wondering if I'm missing something with how NAT rules changes since earlier versions of ASA...
Can anyone help?
Thank you
Mario Rosa
Hello
The only reason to see a NAT rule that is configured at the top for not having applied are
- The "permit same-security-traffic intra-interface" is NOT configured, but in this case, it's since we have already taken the exit "packet-tracer"
- There is of course the possibility that networks of NAT rules match any traffic entering the ASA
- Naturally, there is the change of a bug that there were several.
If there is no clear reason for the rules does not match NAT do not, then I suggest opening a case of TAC or upgrade / downgrade to another level of software to determine if an error is the cause.
I don't know if you mentioned the software level that you use?

Hi guys!
I have a little problem with my setup.
I would like to join the Y in X host through a VPN tunnel.
My setup works fine, until I have add this static nat entry:
-ip nat inside source static 10.20.20.1 198.41.10.1
In this case, the tunnel endpoints cannot reach each other (172.16.13.1 <->172.16.13.2).
The Ext_Router made the Nat translation and the tunnel is located between Ext_Router and R7.
What is the problem?
The configuration files are attached.
Hello
First, I would like to say that my relationship with GRE + IPsec have been pretty slim.
But what seems to me looking at the configurations and NAT, is that you must following configurations with respect to NAT on R5/Ext_Router
- Configuration of PAT translation for LAN 2 networking using the IP address of Serial 0/0 as a PAT address
- A static NAT for a single host LAN that uses ALSO address IP Serial0/0 for the translation.
If the NAT router operation is something like the Cisco PIX or ASA. The static NAT completely replaces PAT (overload) configuration and therefore no user belonging to networks source ACL 1 wont be able to use the NAT and therefore traffic will not work for them but should probably work for the host of the 10.20.20.1 Static NAT?
Could be the problem? Pourrait 198.41.10.x another IP, be used for the static NAT?

Problems of NAT with AnyConnect and 8.3 of the ASA
I have set up on an ASA 8.3 AnyConnect. I'm properly connect and pulling an IP from the pool that I created. The problem I have is that I'm quite see "receive" packets in the AnyConnect details. I know about the ASA 8.2 and earlier you would use a "waiver" NAT to do the translation of the identity. How is what is done with 8.3 and later?
Within 8.3 and later networks are defined as objects using groups of objects. Then, these groups of objects are referenced in the NAT statement to define both pre and post NAT (real / mapped) addresses.
network of the LOCAL_LAN object
Subnet 192.168.0.0 255.255.0.0network of the REMOTE_LAN object

I have install esxi 4 on my server with 1 ip (xxx.xxx.xxx.xxx) public static
Then, I created 1 vswitchs named 'DMZ' with no attached NICs.
I have therefore 2 vswitch (vswitch 0 (GRPE Managerment ports) and VM Machines (WAN)) and 1(For DMZ) vswitch). I installed PFsense by using 2 NICs (Machines (WAN) VMS on vswitch 0 and DMZ on vswitch 1)
Once installed, I put the on pfsense wan interface to Nic WAN and he attributed ip xxx.xxx.xxx.xxx (the same as the IP for the esxi host).
But the pfsense can not connect to internet and also move towards the gateway.
Could someone please help me in this case?
Can I NAT for virtual machines via pfsense comes with a single IP (xxx.xxx.xxx.xxx)?
Here are the pictures.
Thanks in advance
Once installed, I put the on pfsense wan interface to Nic WAN and he attributed ip xxx.xxx.xxx.xxx (the same as the IP for the esxi host).
You cannot use the same IP address for ESXi host and pfSense... WAN interface that will generate a duplicate IP problem and a server (or both) will not work correctly.

NAT with VMWare Workstation 9-Urgent problems
HelloTry to use NAT in VMware Workstation 9 and am lost in my VM connection.
But when I use the network bridge, it works very well.
Is someone can you please help me solve?
I tried reinstalling VMware workstation for all n No.. times and restored the settings of the Virtual Network Editor as well.
Help, please!
It seems that the client does not receive a DHCP address? Assuming that the virtual network adapter in the virtual machine settings is 'connected' (which, I guess, because you said Bridged works very well), you can check if there is a problem with the installation. Please run services. MSC (or net start from the command line) to see what VMware services are running on the host computer.

I use a time for Backup Capsule and WIFI. I have a cable box to receive Internet.
I am positioning the Ooma telo between the internet modem and TC box.
It works, BUT I have a flashing yellow light of TC. I guess that's a double NAT error.
I know that to go to the wireless utility but you choose DHCP only or bridge?
If so, should I put a static IP address... If Yes, how should I do this?
If someone here could provide simple step by step instructions... the above may SEEM like I know what I got kindof... but I don't.
Thank you.

Hi all
I have the following situation
The following rules of the static nat
static (inside, outside) tcp 200.200.200.200 80 10.0.0.200 80 netmask 255.255.255.255
static (inside, outside) 200.200.200.200 tcp 8080 10.0.0.200 80 netmask 255.255.255.255
I would redirect all packets destined for port 8080 and 80 IP address 200.200.200.200,
to the private IP address on port 80 10.0.0.200.
I tried to do that the ASA said there is already a rule, there is a way it be done?
Kind regards.
I don't think you can use port forwarding using the same local destination IP on port 80 in this way, fw will give you duplicate static entries.
You can however get around and give 10.0.0.200 NIC a secondary IP address i.e. 10.0.0.201 and make electricity as follows.
static (inside, outside) tcp 200.200.200.200 www 8080 10.0.0.201 netmask 255.255.255.255
static (inside, outside) tcp 200.200.200.200 80 10.0.0.200 80 netmask 255.255.255.255
See examples of port forwarding
