• client ipSec VPN and NAT on the router Cisco = FAIL

  I have a Cisco 3825 router that I have set up for a Cisco VPN ipSec client.  The same router is NAT.

  ipSec logs, but can not reach the internal network unless NAT is disabled on the inside interface.  But I need both at the same time.

  Hello

  I think that you need to configure the ACL default PAT so there first statemts 'decline' for traffic that is NOT supposed to be coordinated between the local network and VPN pool

  For example, to do this kind of configuration, ACL and NAT

  Note access-list 100 NAT0 customer VPN
  

  access-list 100 deny ip 10.0.1.0 0.0.0.255 10.88.0.0 0.0.0.255
  

  Note access-list 100 default PAT for Internet traffic
  

  access-list 100 permit ip 10.0.1.0 0.0.0.255 ay

  overload of IP nat inside source list 100 interface GigabitEthernet0/0

  
  EDIT: seem to actually you could have more than 10 networks behind the router

  Then you could modify the ACL on this

  Note access-list 100 NAT0 customer VPN
  

  access-list 100 deny ip 10.0.1.0 0.0.255.255 10.88.0.0 0.0.0.255
  

  Note access-list 100 default PAT for Internet traffic
  

  access-list 100 permit ip 10.0.1.0 0.0.255.255 ay

• Unable to connect to the site Web SSL VPN with firewall zone configured

  I recently updated my 2911 company and set up a firewall area.  This is my first experience with this and I used Cisco Configuration Professional to build the configuration of the firewall first and then edited the names to make it readable by humans.  The only problem I can't solve is to learn site Web SSL VPN from outside.  I can navigate the website and connect without problem from the inside, and even if it was useful to verify that the Routing and the site work properly it is really not what I.  I don't get anything on the syslog for drops because of the firewall server, or for any other reason but packet capture show that no response is received when you try to navigate to the outside Web site.  I am currently using a customer VPN IPSEC solution until I can get this to work and have no problem with it.  I have attached a sanitized with the included relevant lines configuration (deleted ~ 400 lines including logging, many inspections on the movement of the area to the area and the ipsec vpn, which I already mentioned).  I searched anything about this problem and no one has no problem connecting to their Web site, just to get other features to work correctly.  All thoughts are welcome.

  Glad works now. Weird question, no doubt.

  I guess that on the deployment guide said that the firewall will not support inspection of TCP to the free zone, however, class nested maps are used to accomplish this, to be completely honest, I think it's a mess and the best thing to do is action past to auto for the protocols that you want and then drop the rest.

• Inside Source NAT from the remote host and VPN from Site to Site

  Hi all

  I was in charge of the construction of a vpn tunnel with a firewall PIX of our business partner company and ASA of the other company of the firewall.  Traffic will be A partner business users will access my company Citrix server.  I want to source-pat the user traffic partner company to PIX of my business within the interface to its entry in my LAN to access my company Citrix server.  The partner company will be PAT'ing their traffic from users to a single ip address - Let's say for discussion end is 65.99.100.101.  There is the site to site vpn configuration, and configure nat be performed to allow this traffic in accordance with the above provisions.

  I'm more concerned about the accuracy of the configuration of the domain encryption because NAT is involved in this whole upward.  My goal is to NAT (of the other company company a) ip address to a routable ip address in my company network.

  The fundamental question here is should I include the ip address of real source (65.99.100.101) of the company the user or IP natted (10.200.11.9) in the field of encryption.

  In other words should the encryption field looks like this

  OPTION A.

  permit ip host 10.200.11.103 65.99.100.101

  OR

  OPTION B

  permit ip host 10.200.11.103 10.200.11.9

  I'm inclined to think it should look like OPTION A.  Here's the part of MY complete SOCIETY of the VPN configuration.  I've also attached a diagram illustrating this topology.

  Thanks in advance,

• Phone to the Migration of SSL VPN proxy telephone

  We are working with a client who moves from UCM 7.x to 9.x and a proxy phone in place today. With the Proxy of phone is no longer supported in 9.x, they are forced to move to the SSL VPN for IP phones. The design doc indicates that phones need to be high on the internal network first download configs, certificates, etc. before going out on the field.

  Yes, there is no known workaround solution to configure remote users phones WITHOUT bringing within the network. For multinationals, this could prove to be a HUGE headache.

  jyoungta replied to another thread with this:

  "If you can get a copy of the new phone config file and put it on a tftp which is accessible via the internet, then you can just point the phone to the server tftp (alternate tftp server option).  He's going to go and grab the new config file. »

  It sounds good (Thanks Jay) but it looks easy... too easy. Is there a procedure that we follow documented, we can follow?

  (Forgive my lack of specific technical knowledge, I'm in management)

  -Sam

  Hello Sam:

  I was able to convert a phone of attorney to anyconnect vpn with a single deployment of standard certificate.  The phone had something to do with the CallManager via TFTP outside the network as part of the phone proxy configuration.

  I have configured the anyconnect VPN settings phone on the SAA.

  Pushed the ASA SSL certificate to the CallManager

  Configured the CallManager to the VPN phone settings appropriate.

  Apply the common on the phone phone settings and reset the phone.

  -Until ' at this point, you just follow the guide.  https://supportforums.Cisco.com/docs/doc-21469

  In the network settings on the phone, I changed the TFTP replacing (necessary for telephone proxy) public IP address to the private IP (required for anyconnect VPN).

  Delete the CTL under settings - configuring security - trusted list

  Reset the phone

  -At this moment, I saw the phone reboot, connect to the VPN and I could check the operation of the VPN on the phone and make a few prank calls.

• Configuration of the router to allow VPN traffic through

  I would like to ask for assistance with a specific configuration to allow VPN traffic through a router from 1721.

  The network configuration is the following:

  Internet - Cisco 1721 - Cisco PIX 506th - LAN

  Remote clients connect from the internet by using the Cisco VPN client. The 1721 should just pass the packets through to the PIX, which is 192.168.0.2. Inside of the interface of the router is 192.168.0.1.

  The pix was originally configured with a public ip address and has been tested to work well to authenticate VPN connections and passing traffic in the local network. Then, the external ip address was changed to 192.168.0.2 and the router behind.

  The 1721 is configured with an ADSL connection, with fall-over automatic for an asynchronous connection. This configuration does not work well, and in the local network, users have normal internet access. I added lists of access for udp, esp and the traffic of the ahp.

  Cisco VPN clients receive an error indicating that the remote control is not responding.

  I have attached the router for reference, and any help would be greatly apreciated.

  Manual.

  Brian

  For VPN clients reach the PIX to complete their VPN the PIX needs to an address that is accessible from the outside where the customers are. When the PIX was a public address was obviously easy for guests to reach the PIX. When you give the PIX one address private, then he must make a translation. And this becomes a problem if the translation is dynamic.

  You have provided a static translation that is what is needed. But you have restricted the TCP 3389. I don't know why you restricted it in this way. What is supposed to happen for ISAKMP and ESP, AHP traffic? How is it to be translated?

  If there is not a static translation for ISAKMP traffic, ESP and AHP so clients don't know how to reach the server. Which brings me to the question of what the address is configured in the client to the server?

• Router Cisco SSL VPN Configuration

  Hello support.

  A question concerning this scenario.

  One of our clients has currently SSLVPN enabled for remote users and I was wondering if there is anyway to configure a remote Cisco router to connect via IPSEC at this endpoint SSLVPN? the idea is simply to set up the tunnel without requiring changes on my end of customers.

  Thanks in advance.

  Ivan Chacon

  Hello

  IPSEC and SSLVPN are 2 different configurations, there is no way to have a router configured for IPSec and connect to another without changing this end as well.  You can run IPSec and SSLVPN on the same router, however.

  There are a lot of IOS Lan to Lan configuration guides, or if you want the router to act as a client, are looking to make EZVPN.

• NAT on the router WRT120N.

  Hello

  I buyed a new router the WRT120N and it works well

  But I have a question I had this problem on my other router also but it was easy to stop this it is called NAT, I have problems with it on a game called Gunz.

  7700-7800 TCP and UDP ports.

  I already found the option turn off NAT, but then I have no more Internet if disable this I have to write anything, because he wants to STATIC ROUTING.

  I tried portforwarding wich only helped on my old router, but it does not help.

  Eny one tell me what I must write in the stuff of static route? I don't know enough about routers, but this?

  Thank you

  Niels

  I guess that the 168.192.1.104 in the port forwarding is a typo.

  The computer is configured for DHCP. You must ensure that you configure a DHCP reservation for the computer.

  Your router is connected directly to the internet. It has a public IP address. Good.

  Haven't you set up redirects to single port or port triggering?

  If this isn't the case, the transmission seems to be set up correctly.

  Do you run the firewall on the computer?

• SSL vpn through the same internet connection to another site

  Hi, I have a network with a box of Juniper SSL that connect to port DMZ ASA5510, wher outside the ASA is the same outside the box of SSL vpn.

  To access issues eno hav network internal at all.

  Now, I need VPN SSL Juniper box remote users and internal conenct o my remote sites, who take the client connection through an internet router (Cisco throug site to site vpn IPSec) again to the th eremote site.

  Is it possible, my hunch is Yes "can be done."

  Currently, I'm fitting get no where, I get no hits ASA DMZ ACL if I try to access the remote site of the SSL vpn client resources.

  Schema attached

  Any help would be appreciated

  Shouldn't be a problem.

  On the Juniper SSL, you must check if the roads has been added to the remote IPSec LAN point to the ip address DMZ ASA instead of pointing to the internet through the Juniper SSL box.

  You need to configure NAT exemption on the ASA box between the pool SSL subnet to the Remote LAN of IPSec. As a result, you must also include the SSL subnet to Remote LAN subnets in the crypto ACL and mirror image ACL on the remote site ACL Cryptography.

  Hope that helps.

• Third-party SSL VPN ended the DMZ ASA

  Hi all

  Any help is appreciated. Is it possible:

  I have a DMZ set in ASA 5520, and worked well so far. The DMZ subnet is 192.168.10.0/24 and IP on the DMZ interface is 192.168.10.1. Now, I'm trying to add a third-party SSL VPN device (not Cisco). The device has an IP 192.168.10.101. The SSL VPN appliance will give IP addreess SSLVPN customers in the range of 192.168.20.x. After the connection is established, the client is indeed getting the IP addr 192.168.20.x. However, clients are unable to connect to the internal LAN. If I change the IP address range clients on the same subnet that the area demilitarized, everything works. My question is that, as customers SSLVPN are complete on the demilitarized zone and get a different subnet IP address, how can I / road map these addresses before they6 can access internal network inside the interface, or it can be done at all?

  All advice is appreciated.

  You just need to add the routes appropriate on the SAA for this pool. And also on any Layer 3 routing devices inside the ASA.

• VPN site to Site using the router and ASA

  Hello

  I have a Cisco 1812 router that is configured for remote access VPN using IPSec (Cisco VPN Client), my question is if I can configure a Cisco ASA 5505 to connect to the router as a VPN from site to site.

  Thank you

  Karl

  Dear Karl,

  Yor are right, in this case you can create a tunnel vpn site-to-site between devices or you can configure your ASA as hardware VPN client. That is to say; Easy VPN.

  For the same thing, you can consult the document below.

• AnyConnect SSL VPN Split tunneling problem

  Hello

  We have home users that VPN in on a regular basis, but when they VPN in they cannot print locally or to connect to local resources.  Is there a way to activate the split for all remote users VPN tunneling?  It is not possible to add all the remote subnets, especially since I don't know which subnets are used and it would be a question of management.  I noticed that when I connect to the House a new route is added to my PC, who prefers the VPN link.

  I noticed one of the options with the client Anyconnect is 'enable local LAN access (if configured) '.  Can I use?

  Thanks in advance.

  Hello

  According to my understanding, you need to connect to your local printers while you are connected to the ASA via SSL VPN.

  You can do this by creating a policy of exclusion of tunnel split on SAA and the local lan access on the client option, or you can use the profile AnyConnect allowing local lan access.

  Please find the link below: -.

• URL via SSL VPn access

  Dear members

  Please see the diagram for an easy understanding of the issue.

  I am facing a problem with the SSL VPN configured on ASA 5520. Here's the simple network topology.

  customer has an ERP server inside the segment, which is runniing Apche / Tomcat 5.5 and listening on port 8204.Complete URL to access the installed application is

  http://192.168.2.1:8204 / system/servlet/login

  ASA connects to a router in parameter, which has a configured AS VPN remote access. Cisco VPN client users can access this URL easily when they connect via VPN, also if I create a static translation for this IP 192.168.2.1, the full URL is accessible from the outside, but the problem of SSl VPN, when I enter the URL, nothing appears, and Session expires, however if I just enter http://192.168.2.1:8204 , Apache /Tomcat Page opens menas through SSL VPN can I reach the web server running on 192.168.2.1, but this particular URL is not accessible.

  Here apache on the ERP server is listening on a nonstandard port, which could be the reason, I need to create a forwarding port or "smart."

  I already tried with port forwarding, but that has not solved the problem.

  All entries from your side will be highly appreciated.

  Thank you

  Ahad

  Hi Ahad,

  When you access the server ( http://192.168.2.1:8204 / system/servlet/connectionURL) from the inside, the URL in the browser address bar remains the same? Or it redirects?

  On the login page is a java applet?

  Now, there are several things to try:

  -do a "view page source" on the work (internal or via IPsec vpn) login page and again on the default (via webvpn) page and compare - that provides any suspicion?

  -You can install a software like Charles SSL Proxy (http://www.charlesproxy.com/ - note this is not a product of Cisco, or approved by Cisco) to see exactly what is happening above the SSL tunnel (i.e. it will show you the HTTP request in the browser to the server and the response.) Again, you can do this for both a job and the absence of case to compare.

  -as a possible solution: create a bookmark HTTP on the portal of this URL and select "smart tunnel" for her.
