VPN site to Site with NAT and Port forwarding on a 871
Hello
Could someone please look at the config 871 router attached and tell me where I'm wrong!
VPNs all work, work, BUT anyone trying to connect to a port that is sent through the VPN port forwarding fails.
In the config attached Port 3389 (RDP) is sent to an internal server, if you connect to the external interface Internet connection is made and it works well, but if someone tries to connect to the IP address internal to that same server through VPN, it does not.
We've added commands to stop working on the lines VPN NAT, but these do not seem to work.
What Miss me?
Thank you in advance and I will adjudicate all useful responses.
It is a common problem. Yes you added controls to prevent NAT to work above the tunnel, but your static nat port to port 3389 takes precedence over the generic nat command, and there not all orders top to prevent it is nat would be above the tunnel.
I wrote an example configuration for this some time, see here for more details:
http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_configuration_example09186a0080094634.shtml
If all goes well, he explains everything. Note that it is for a general order static host, not a static port that you have, but the concept is exactly the same. Just add a statement roadmap on the end of your static command of the port, and this route map - will reference an ACL that denies are used when going up above the tunnel.

You must ensure that there is no NAT 0 ACL statement because it will take precedence over the static NAT.
You don't need:
Global 172.26.0.1 - 172.26.0.254 10 (outside)
NAT (inside) 10 access-list nattoyr
Because it will be replaced by the static NAT.
In a Word is enough:
nattoyr to access ip 10.0.0.0 scope list allow 255.255.255.0 10.1.252.0 255.255.255.0

ASA (v9.1) VPN from Site to Site with IKEv2 and certificates CEP/NDE MS
Hi all
I am currently a problem with VPN Site to Site with IKEv2 and certifiactes as an authentication method.
Here is the configuration:
We have three locations with an any to any layer 2 connection. I created each ASA (ASA5510 worm 9.1) to establish one VPN of Site connection to the other for the other two places. Setting this up with pre shared keys and certificates that are signed by the CA MS administrator manually work correctly.
But when we try to enroll these certificates through the Protocol, CEP/NDE his does not work.
Here are my steps:
1 configure the CA Turstpoint to apply to the certification authority
2. request that the CA through the SCEP protocol works fine
3. set up a Trustpoint and a pair of keys for the S2S - VPN connection
4. registration form identity certificate CA via the SCEP Protocol with a one time password works fine
5. set the trustpoint created as for the S2S - VPN IKEv2 authentication method.
Now I did it also for the other site of the VPN Tunnel. But when I ping on a host that is on a different location to make appear the Tunnel VPN - the VPN session is not established. In the debugs I see that there are a few problems during authentication of the remote peer.
On the MS that I see that the certifactes of identity for both ASAs are communicated and not revoked or pending state. The certificate based on the model of the "IPSec (Offline).
When the CA-Admin and a certificate me manually based on a copy of the model of "Domaincontroller" connection is successfully established.
So I would like to know which is the correct certificate for IP-Sec peers template to use for the Protocol, CEP and MS Enterprise CA (its server 2008R2 of Microsoft Enterprise)?
Anyone done this before?
ASA requires that the local and Remote certificate contains EKU IP Security Tunnel Endpoint (1.3.6.1.5.5.7.3.6) (aka IP Security Tunnel termination). You can create a Microsoft CA model to add.
If you absolutely must go with the 'bad' cert, there is a command
ignore-ipsec-keyusage
but it is obsolete and not recommended.
Meanwhile at the IETF:
RFC 4809
3.1.6.3 extended Key use
Extended Key Usage (EKU) indications are not required. The presence
or lack of an EKU MUST NOT cause an implementation to fail an IKE
connection.

IPSec Tunnel between Cisco 2801 and Netscren 50 with NAT and static
Hello
My problem isn't really the IPSec connection between two devices (it is already done...) But my problem is that I have a mail server on the site of Cisco, who have a static NAT from inside to outside. Due to the static NAT, I do not see the server in the VPN tunnel. I found a document that almost describes the problem:
"Configuration of a router IPSEC Tunnel private-to-private network with NAT and static" (Document ID 14144)
NAT takes place before the encryption verification!
In this document, the solution is 'routing policy' using the loopback interface. But, how can I handle this with the Netscreen firewall. Someone has an idea?
Thanks for any help
Best regards
Heiko
Hello
Try to change your static NAT with static NAT based policy.
That is to say the static NAT should not be applicable for VPN traffic
permissible static route map 1

Cisco ASA VPN Site to Site WITH NAT inside
Hello!
I have 2 ASA 5505 related to IPSEC Tunnel VPN Site to Site.
A 192.168.1.0/24 'remotely' inside the network and a local "192.168.200.0/24' inside the network (you can see the diagram)
The local host have 192.168.200.254 as default gateway.
I can't add static route to all army and I can't add static route to 192.168.200.254.
NAT the VPN entering as 192.168.200.1 or a 192.168.200.x free to connect my host correcly?
If my host sends packet to exit to the default gateway.
Thank you for your support
Best regards
Marco
The configuration must be applied on the SAA with the 192.168.200.0 subnet it is inside, there must be something like this:
permit 192.168.1.0 ip access list VPN_NAT 255.255.255.0 192.168.200.0 255.255.255.0
NAT (outside) X VPN_NAT outside access list
Global (inside) X Y.Y.Y.Y (where the Y.Y.Y.Y) is the ip address
If you have other traffic on the vpn through the tunnel that requires no nat, then you must add external nat exemption rules since these lines above obliges all traffic through the asa to have a nat statement.
See if it works for you, else post your config nat here.

VPN site to Site with NAT (PIX 7.2)
Hi all
I hope for more help with config PIX. TBH I would classify myself as a newb on PIX, only dabbling in it every 6 months or so...
I have to configure a VPN site-to site between our UK and US Office, to replace our frame relay link. I have configured multiple VPN site to site on the before PIX, so am reasonably okay with the appearance of the config of who. What is a new concept for me is the needs of NAT'ing between the IPSEC tunnel.
The U.S. Agency requires us to NAT source addresses (i.e. 192.168.1.0) usable on their side address (i.e. 143.102.89.0). The tunnel must then be set to encrypt traffic between 143.102.89.0/24 and 172.24.0.0/14.
I added the following config and hoping to test it at the U.S. office happens online today.
If I Ping from 192.168.1.0 to 172.24.x.x source and run a SH NAT inside, the NAT translation seems good.
is the intellectual property inside 192.168.1.0 255.255.255.0 outside 172.24.0.0 255.252.0.0
static translation at 143.102.89.0
translate_hits = 4, untranslate_hits = 0Could someone please go through the following lines of config and comment if there is no error?
Thank you very much

You can configure NAT/Global pair for the rest of the users.
For example:
You can use the initially configured ACL:
policy-nat-dallas-list of allowed extensive access ip 192.168.1.0 255.255.255.0 172.24.0.0 255.252.0.0
NAT (inside) 1 access list policy-nat-dallasGlobal 1 143.102.89.x (outside)
The static statement that you configured previously will take precedence over the above. So the printer gets statically using a NAT to 143.102.89.10, and the rest can do another ip address 143.102.89.x PATed.
Please note that for PAT, traffic can only be initiated from 192.168.1.0/24 LAN to 172.24.0.0/14, not the other way around.
Hope that helps.

local host to access the vpn site to site with nat static configured
I have two 881 routers with vpn site to site between them. I have a static nat on the router for a Web server that is accessible from the internet. I can't access the Web server through the vpn. All other traffic is fine its VPN. I think that there is a problem with the NAT. Here are the relevant configuration lines.
IP nat inside source overload map route SDM_RMAP_1 interface FastEthernet4

If you just add the VPN and the road map, try to clear the existing translation and see if you can access it via its private of the Remote LAN VPN ip address.

Hello Experts
We intend to set up a VPN site-to site between two sites, sites, Site & A B such as shown in the attached diagram.
The LAN on SIte A is 10.8.1.0/24 who are planning to NAT on the ASA5505 to 192.168.42.0/24 because this is the range that is allowed on the firewall on the remote end (Site B ASA 5520)
What type of configuration requires we on the firewall of the Site regarding the interesting traffic.
Natted IPs will be the interesting traffic?
Is there another thing we have in other mind while configuring the ASA for the scenarios.
Help would be appreciated.
ACL "crypto-NAT" of my example will be the NAT traffic that source of 10.8.1.0/24 for 10.3.0.0/24 to match 192.168.42.0/24.
For example:
10.8.1.1 will be coordinated to 192.168.42.1 when traffic is destined to the 10.3.0.0/24 subnet.
10.8.1.2 will be coordinated to 192.168.42.2 when traffic is destined to the 10.3.0.0/24 subnet.
etc etc.
If you have another remote subnet, you are right, you just add the extra line to the crypto-NAT and crypto-ACL. So, you will have the following lines:
IP 10.8.1.0 allow Access-list crypto-NAT 255.255.255.0 10.3.0.0 255.255.255.0
10.8.1.0 IP Access-list crypto-NAT 255.255.255.0 allow 10.5.0.0 255.255.0.0
Crypto ip 192.168.42.0 access list ACL allow 255.255.255.0 10.3.0.0 255.255.255.0
Crypto ip 192.168.42.0 access list ACL allow 255.255.255.0 10.5.0.0 255.255.0.0

Site to Site with ASA and FortiGate
I have setup a VPN site-to site between my ASA and FortiGate customers. The tunnel rises with success, but we can not pass traffic. When I do a packet capture on my ASA, I see traffic on the port of entry as usual, but on the output port, the source address gets NAT had I checked all statements of NAT, and there is a statement NAT exempted from the entry port to the port of exit and in the VPN configuration.
Then your oder of NAT statements in probably wrong. The dynamic NAT for outgoing traffic must be at the end (I put them always in article 3), while the Exemption must be at the beginning of Section 1.

Hi all, thanks for looking. I'm a very basic user to a Cisco ASA 5510, I tend to do most of the things in the ASDM GUI interface.
We need to create a site to site with a client connection. It's pretty easy but there is a caveat, we can use our internal IPS that they already use the range elsewhere. If we gave them two different IP, for example 192.158.22.101 and 192.158.22.102. I created the site to the site using these two survey periods, but these do not exist internally on the machines because they are not IPs on our network, which is using 192.158.44.0.
The question I have is how can I get the IP addresses 192.158.44.101 and 192.158.44.102 to become 92.158.22.101 and 92.158.22.102 before being sent via this connection. I tried to add the NAT to the object of an IP address related, but I'm obviously missing something.
The other option, I do not fear to do, is to add a new range of internal IP 192.158.22.0 addresses, but I don't know how do either.
Any help would be appreciated, I'm really bad here and spent two weeks on this subject already. I searched for it, but it seems that it is either too basic for most people wonder or slightly different, for example, they have control of the two sites.
Hello
Add to that dieng said here is the config for NATTING as two IPS 192.158.44.101 and 102:
network object obj - 192.158.44.101
Home 192.158.44.101
network object obj - 192.158.44.102
Home 192.158.44.102
object obj -192.158.22.101 network
Home 192.158.22.101
object obj -192.158.22.102 network
host 192.158.22.102
object obj remote network
10.x.x.x subnet 255.255.255.0
You need two NAT statements for this:
NAT (inside, outside) source dynamic obj - 192.158.44.101 obj -192.158.22.101 destination static obj-remote obj-remote
nat source (indoor, outdoor) obj dynamic obj - 192.158.44.102 - 192.158.22.102 destination static obj obj-remote control-remote control
It will be useful.

VPN and port forwarding problem
Hello
I configured a VPN (IPSec) between 2 sites on Cisco 881 - K9.
The server 'A', which the 192.168.0.X address must be accessible on port 80, 8080 and 90 of the public network.
I have configured the ports of shipment with the command:
IP nat inside source static TCP 192.168.0.X 90 interface fastethernet 4 90
IP nat inside source static TCP 192.168.0.X 80 4 80 fastethernet interface
IP nat inside source static TCP 8080 interface fastethernet 4 8080 192.168.0.X
The server is accessible from the outside, the site in which it is located.
But there is a problem with the second site:
- I ping the server with its local address 192.168.0.X
- But when I try to open a Web page that is using port 80 or 8080 or 90, the server appears inaccessible
It seems that the problem is due to the translation of port because when I delete the configuration of port forwarding is no problem over on the second site.
Thanks for your help
Hello
You need conditional NAT.
When you want to Port Forwarding to work just for a part of traffic, e.g. when access to the server from the Internet
but not for traffic entering via VPN, you can add a roadmap to the end.Thus,.
IP nat inside source static TCP 192.168.0.X PUBLIC_IP 4 xx xx map route VPNThe road map tells when it is NAT that will to spend.
It will always happen, but when traffic is coming from the VPN.Now... the problem is that you can add a roadmap, when you have a rule of Port forwarding to an IP address (and not an interface).
Anyway, give it a try and let us know.
Federico.

NETGEAR ProSafe VPN Firewall SRXN3205 and port forwarding?
Hi, this is a long shot, but I'm pulling my hair out at this point and can be a bit over my head, as I am new on network
Small short story, I have two servers, one is the NAS box (IE if I connect via the internet to the site via public IP network from home, I get it that site says 'my actions' I insert login and pass and get access to them.)
That is, everything is peachy.
The problem is when I try to connect to my FileMaker Server I'm not and instead, he takes me to the login NAS box. So I think ok, I need to port forward (5003 for filemaker) to go to different PC local LAN(192. etc)Security > firewall > Add Service entering:
Service: fmserver
Action: Always leave
Send to LAN Server: unique address 192. etc is filemaker installed on (and different on a NAS)
Definition of Port number: 5003<-- is="" this="" right?="" how="" else="" would="" you="" indicate="" you="" want="" all="" connections="" on="" this="" port="" to="" go="" to="" this="" specific="" lan="" machine="" from="" internet="" instead="" of="" default="" which="" seems="" to="" be="">-->
rest is default, I click on apply.Here's what I don't understand. In the table of incoming Services, (security > firewall) I have two local IP in the list, a SIN, the other for Filemaker. But only the top works and can be connected to. I can move every top position and it will work, but they will not work at the same time, just the one that sits on the top of the sad Smiley page
and yes I read the manual again and again and don't know how I'm screwing up the port forwarding on this point, even if I am brand new to probably something stupid Smiley Happy (our work IT guy is gone so tried to get involved through this somehow)
Any help would be appreciated.
Hello sinieq,
There is a hierarchy on incoming service table, which is normal. I see 4 services added using "ANY" (ALL use any port number) you will need to remove/disable these because of the rule of the hierarchy on the table, all other services will be ignored when EVERYTHING is used. What is the port number used by the NAS Server? I don't see a port defined to access NAS. Try disabling services by using "ANY" and try again by adding the translation to the port number of the NAS.
Let us know what happens.
Thank you
