• NETGEAR WNR1000v3 - Public IP instead of the private IP address

  Hello

  I moved into a new House and put in place and internet service here. So, I got my own modem + router (WNR1000v3). The router itself works fine and provide internet.

  However, when I tried to access the routerlogin.net OR IP address, the application expires. Which means that I can not set a password to protect my network.

  I called support and thought that my router is giving a public IP address instead of the private IP address. Any ideas how I can reconfigure the router working properly?

• [View 5.3] Connection to security through Blast Server redirected to the Local IP address private view Desktop in Google Chrome

  Hello

  I am currently facing a questions in my test harness which happens when I connect to public IP address on server security by the breath. No problem if I connect using view Client.

  Using the breath, I can log on, select a desktop view, then the url of the Web page showing my ip Server security for about 10 seconds and then I was redirected to the private IP address of NAT from the desktop view target and of course I couldn't connect.

  

  Note: The local private ip address redirection does not happens if I configured to connect to show the connection to the server through breath.

  I have:

  • Self-signed SSL installed without warnings
  • activated the tunnel to connect to the server
  • Tunneling on server security enabled
  • disabled all firewall for testing purposes
  • locally defined in the host file to resolve my domain name full of security server static IP used in my office. (vsecurity.icliq.com in this case)
  • required ports are configured with port forwarding in my router from office

  

  I hope someone could throw some light on this issue. Thank you

  Yes, the option of Blast Secure Gateway is used to ensure that Blast connections are routed from your browser by the server security (or connect to the server). That's what you want to access remotely. If you do not select this option, Blast connections will be direct to your virtual desktop. This is for internal connections.

  It goes the same for PCoIP and PCoIP Secure Gateway.

  Hello guys,.

  I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

  The question statement not the interface pointing to ISP isn't IP address private and inside as well.

  Firewall configuration:

  Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

  Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

  I have public IP block 199.9.9.1/28

  How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

  can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

  If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

  I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

  Please help with configuration examples and advise.

  Thank you

  Eric

  Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

  3 options:

  (1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

  OR /.

  (2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

  OR /.

  (3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.

  you want to configure static NAT.

  Suppose that 10.10.1.5 is the server inside and 193.234.211.12 is your free external IP. Joanie configure this line:

• Internal address NAT before moving on to the VPN

  Hi all

  I was instructed to retire a VPN concentrator 3000 and its replacement by an ASA 5520.  I'm trying get a handle on how to implement the NATs and ACL, since most of my experience is remote access VPN, not from site to site.  In addition, I have not configured a VPN 3000 in about 6 years so I'll have to re - learn a lot from the interface.

  The VPN 3000 has a feature called NAT LAN-to-LAN rules that basically allow NAT address on your internal network to an address on the 'local' network for LAN-to-LAN connection, so it can then walk through the tunnel to the remote side.  The configuration looks something like this in the VPN 3000:

  Network source translated network remote network

  172.16.3.151 192.168.200.151 10.3.136.0

  That seems to me like a "political static NAT" in ASDM.  If I have one of those implemented, who should translate 172.16.3.151 to the inside interface for 192.168.200.151 inside (Yes, the same interface) interface which (logically) then should be picked up as "interesting traffic" by the crypto-plan and sent through the VPN tunnel.  However, appears not to be the case - the two 'followed package' in the ASDM and traceroute of the source workstation show packages inside the interface and then sent right on the external interface to the internet router (which then removes the packages because they have a private IP address).

  I don't know I missed something fundamental... what else do I need to do the pick-up card crypto traffic NATted?

  Hi Greg Dickinson,.

  This is the scenario. You can have several object groups in your scenario is possible.

  Original of your LAN IP on the Site b LAN IP Allow acl must be used for the NAT/PAT.

  !

  NAT_ACLpermit 172.16.3.0 ip access list 255.255.255.0 10.3.136.0 255.255.255.0

  public static 192.168.200.0 (indoor, outdoor) 255.255.255.0 access-list NAT_ACL

  !

  CryptoACL 192.168.200.0 ip access list allow 255.255.255.0 10.3.136.0 255.255.255.0

  !

  crypto map outside_map 1 corresponds to the address CryptoACL

  Your IP NAT/PAT to the @ Site of subnet IP LAN/IP B will be the Cryptoacl for the VPN.

  So, whenever you hit traffic for a site of LAN you will hit it NAT/PAT and translates.

  Then your crypto acl will be with your PAT IP and it should synchronize with Site B.

• The IP address private VC directly to the public IP address

  Hello

  I'm a bit puzzled as to why a specific call, I saw worked for a couple of guests and wonder if there was no change in the situation in the H.323 protocol that allows a form any NAT crossing built natively into the codec without involving and external gateway function.

  the reason I ask is the following

  I got a call from a customer with a codec on a private no routable IP to my system that is located on a public IP address, the client had no details of NAT configuration in the endpoint and was able to call my system directly without issue by calling directly to my public IP address.

  historically now if I had a system on a private IP address was sitting behind a NAT, I expect that the public system IP would see no routable IP address of the H.225 message and try to answer the private IP RTP media that would not go through, it does not seem to occur.

  the call that I have lived seemed ends without problem, media flowed in both directions.

  My endpoint is a Cisco edge 85 on the version of the firmware F9.x

  the other codec parts is an 85 edge on the version of the firmware F9.x

  My codec is on a public IP address that is completely open to the H.323 ports

  the other codec parts is on a private IP address.

  while I can't call the other party, the other party may call for me, and I wonder how it worked, taking into account the fact that there is no gateway service aware H.323 in the call, either a VCS or aware firewall H.323.

  Experience, firewalls and other gateways outside of Cisco, Tandberg, Polycom, have struggled to deal with the new H.323 version, again this is why I'm puzzled as to why the call worked.

  I did a bit of reading on the new version of H.323 and noticed the option multiplex logical channel, however on a call where I saw this apparently works again of a life-size codec for a Codian MCU 4505 shows no sign of this logical channel multiplex, unless that is named differently in the newspapers that the ITU document calls the function.

  greatly appreciated all all all the answers, I don't understand exactly how the firewall impact VC calls.

• What are the typical Ip addresses for NAT?

  Hi all;

  I recently reinstalled my os x and re-installed fusion. I think that by default, NAT has been fixed and I got an IP address of 172.16.182.2. The bridge was simliar.

  Just for peace of mind, it is typical for the vm nat? (like 192.168.1.1 for routers?) I tried to search for him, but either I turn anything or ambiguous corelations affecting me.

• VPN question: ISP assigned a private ip address

  Hi all

  Internet-online-online headquarters VPN 3015 concentrator

  Users remote VPN Client connected to the internet using a private ip address provided by the ISP (cable) is to establish a VPN tunnel, but they can not ping our private network.

  The only way to get the VPN works is when remote users use a public ip.

  It is a question of Cisco VPN Client? Or it has a solution...

  Thanks in advance,

  Kind regards

  Hi Carlos,

  If your ISP gave you a private address, they must use NAT - in which case you will have to enable NAT - T on the VPN concentrator.

  To configure the NAT - T in the world, go to Configuration | System | Tunnelling protocols. IPSec | Screen of transparent NAT and check on NAT - T IPSec case.

• Configure my VCSC with VCSe on the public IP address

  Hi guys,.

  I have a session of control VCS under my company Private IP and I my client on public IP VCSe.

  It will be possible to configure my VCSC with the VCSe after the configuration of the areas?

  The ports must be opened by my team of firewall in this scenario?

  Anything else I need to keep in mind.

  For the record, it is only for the objective test.

  You will appreciate any response.

  Thank you

  Saurabh

  > Then, practically there is no as such risk, and my client can use the public IP address on VCSe

  > without going to double network Option key. (which is used to secure more VCSe).

  Cisco highly recommend VCS-E deploy under the DMZ but it's true, too, many customers deploy VCS - E on public network directly.

  Please visit https://supportforums.cisco.com/thread/2154738?tstart=150 for more information security VCS.

  Next version of the plan to be supported VCS X7.2 software build - in the characteristic basic firewall, which allows configuration to allow/deny list based on the IP / port / protocol which should contribute to better security level or even VCS-E deployment on the public network directly.

  > So, I'll ask my client just buy a public IP address, that's all, and we are ready to go?

  A public IP will demand on VCS Expressway, VCS control can be use the NAT address glow (IE share internet access of the network of offices).

  You must also SRV DNS management (if small deployment probably better to use the external DNS service, there are a lot of company provide a service the two service also responsible DNS hosting and as free service).

• IPSec VPN with private WAN address... Help!

  I am trying to establish an IPSec Site to Site VPN to my company network. I use a Cisco 2811. If I plug a Public IP WAN connection my tunnel past traffic without problem, but if I tell a router in the middle where the 2811 pulls a private IP address of the home router I no longer get a tunnel a success. Any suggestion?

  I have the following instructions.

  FA 0/0
  DHCP IP ADDRESS
  CRYPTO MAP AESMAP

  VLAN 1
  IP ADDRESS XX. XX. XX. XX 255.255.255.240 (public IP)

  IP ROUTE 0.0.0.0 0.0.0.0 FA 0/0

  If this can help clerify the "router" is a CradlePoint (CRT500) that takes the Mobile 3 G and send it to an ethernet port on the WAN port on my router. The installation remains mobile and I rarely get the chance to have a public IP address for my WAN. Currently I use a SonicWall TX 100 router that allows me to VPN to my network of companies. We hope to move all of our mobile kits to the cisco product, but need to find a solution before change can occur.

  If I do 'Show IP Crypto ISAKMP SA' it shows: XX. XX. XX. XX (PUBLIC) <> Active 192.168.0.1.

  My thoughts are that my TCP 500 traffic to the VPN router and when the VPN router sends traffic to the address there SA with it's no the case because it is an ip address private. Limited my knowledge of the works of the VPN, I think only in Phase 1, two addresses must "bind" and NAT cannot be used with VPN? But I keep out hope that this might be a somewhat common question and there is a procedure in place to get around, or maybe I'm just a bad configuration or IP road...

  When I disable card crypto on the FA 0/0 and add NAT to the FA 0/0 and 1 VLAN more change my IP Route to "0.0.0.0 0.0.0.0 192.168.0.1" I get non - vpn connectivity.  Also, I put the address that gets my FA 0/0 in the DMZ of the Cradlepoint.

  Thanks for any help anyone can provide!

  Brandon,

  NAT - T is designed to overcome the problems of NAT/PAT, known in the world of IPv4.

  The big problem is that if you have a public IPv4 address, you will need to run PAT. Packages ESP / AH do not have a port number so that they cannot be PATed. To do this, we enacapsulate IPsec payload inside udp/4500 packages.

  That being said, some providers overcome this problem differently, but it's not THE standard way.

  Your head should see you as PublicIP facig of internet device.

  I agree, that both sonicwall and IOS should work with other IOS. At the same time, it is difficult to say what is happening in the middle.

  I would say that if possible, connect you to a case of TAC, the guys will be able to view your configs and able to solve the problem when it's there. These types of discussions on the forums can go for very long ;-)

• Schedule e-mail alerts are sent to the wrong email address

  When I create an event in the calendar, and then select a custom alert I chose a 'send e-mail' and select an e-mail address and a time so he could send the alert. Which works very well. The problem is when I get the e-mail, the e-mail address alert 'From' is not the one I want it to be sent to (it is a professional e-mail address and it is private alerts). The event I create is a calendar to iCloud and not a work schedule.

  Work email is a Google (IMAP) account, the address I send alerts to is a pop I have also an IMAP to iCloud account.

  I would like alerts to go on the POP account as they do now, but I would like to be sent from the same POP account or the account iCloud and not Google work account.

  I have been looking everywhere for how to define which e-mail account, a calendar alert is sent by e-mail-nothing helped. Any help would be appreciated.
