• ASA 5510 VPN - using a public IP address for the local network

  Hello, I have a problem which is probably very simple, but I can't seem to understand.

  I set up a site IPsec connection to another with a company, something I've done many times before without a problem. I use ASDM to configure this, because it is quick and painless, usually.

  We have one number of other site-to-site currently configured connections and works very well on this ASA, these are configured with the "Protected network - LAN" configured with the IP private of hosts within our network, we want to make available through the separate tunnels. This includes the configuration setting on our ASA for each connection to "guests aside ASA exempt from NAT.

  With this new link, however, the company asked us to use a public IP address for the host that we want to achieve through the tunnel. I don't know why, but they demand it. So I added a NAT rule for inside the host and set up the connection with the public IP address under "Local network". During the test to try to reach a host to their side, the tunnel didn't even try to open.

  What is the method here? I don't see where I'm wrong. I'm guessing that the 'host side ASA exempt from NAT' does not require for this, how if the ASA would know which internal host is the public IP address.

  Any ideas?

  Hi Leo,

  The steps are:

  1. Add the policy rule NAT for the specific host.

  2 - define the IP NAT as your LOCAL NETWORK address in the encryption settings.

  3 make sure that there is no rule NAT exempt for this host to the specific destination.

  What happens if you run a package tracer?

  Thank you.

• The router RSV4000 does support multiple public IP addresses

  I have a client who has a RSV4000 router. The customer also bought a block of 5 usable public IP addresses. I need to be able to assign these public IP addresses for printers, either by configuring a static IP address on each printer directly or through mapping of intellectual property or any other method. Made support for RSV4000 using several treats public IP and if so what configuration is required in the router for printers to be seen by the outside world.

  Hi Winston,

  Thank you for posting. The functionality you need is one-to-one NAT, who does not have the RVS4000. Please watch the RV042 or RV220W for this feature.

• ASA 5520: SSL VPN by using a different IP address that the ASA public IP address

  Hi guys,.

  I'm trying to configure an SSL VPN on a Cisco ASA5520.

  Unfortunately port 443 interface OUTSIDE of the SAA is already used by Microsoft Outlook Web Access and I can not change the configuration of Outlook. This configuration already in place allows me to use the public IP address of the ASA as IP Cisco VPN for the Web page.

  I don't not want to use a different port so to keep life easy for users.

  I have a few available public IPs that I can use so I wanted to use one of them instead of the OUTSIDE of the ASA interface. Any idea how I could do?

  Thank you

  Dario

  Unfortunately you can not use any other public ip address, except the ASA outside IP interface to complete the SSL VPN.

  The only options that you have is to change the Outlook to use another port or the SSL VPN to use a different port.

• Configure the router WRT54G with the PUBLIC IP address and use the DHCP protocol for internal computers

  Hello

  I have a service online Internet with 5 public IP addresses.

  The router and the AP are connected to a switch.

  I would like to set up a WRT54G Router with a public IP address and use DHCP (with private ip address) for the computers that will connect to the AP.

  That the AP is connected to the switch, it is possible that the other wired computers that are connected to the same switch can get an IP from the DHCP?

  Thanks in advance

  In this case, the routing is automatic.

  WRT54G configuration:

  WAN:

  Internet connection: static IP address

  IP address: 180.X. X 170

  Subnet mask: 255.255.255.248

  Gateway: 180.x.x.x (Ex: 180.x.x.1)

  DNS: servers your ISP DNS

  LAN:

  The IP address of the router: 10.10.10.1

  DHCP range: 10.10.10.100 of-online 10.10.10.200

• U - Turn anyconnect with public IP addresses

  Hi all

  I want to configure on an ASA5505 anyconnect but I can't achieve anything when I am connected.

  The customer must receive a public IP address and all traffic must pass through the VPN tunnel.

  The ASA has only one connected interface (outside) and a public IP address.

  Public IP for the VPN subnet is routed to the ASA.

  I don't have any "network" and I don't have a.

  VPN clients must be able to Exchange traffic between them.

  My network configuration:

  -ASA outside IP: x.y.z.19

  -IP address range allocated to VPNS: x.y.z.48 to x.y.z.63

  -There is a firewall that allow the IP VPN to one beach and rule range of VPN IP on the "global" interface

  If I establish a VPN connection, receive an IP address, for example x.y.z.50

  Traceroute from external location to x.y.z.50 for example shows x.y.z.19 as the last hop, if routing is working properly.

  On the VPN client, I cannot ping or achieve anything on x.y.z.19 or 8.8.8.8

  Plotter in x.y.z.50 to 8.8.8.8 ASDM package shows that the package can pass.

  What Miss me? Do I need to use NAT, even if I do not have inside the network?

  Thanks for your help!

  Hello

  Yes. You select allowed same traffic safety intra-interface that come you and go through the same interface... you need to do no. - nat with (outdoors, outdoor) with your vpn address...

• A Site to remote access VPN behind the same public IP address

  Got a problem quite stupid.  We have a VPN from Site to Site configured for a new data center, which will be responsible for general traffic management.  In addition, some users need to use use a VPN client to access certain areas.  The firewall at the Office only has a public IP address, so the two will come to the Site to Site VPN for remote access from the same source.

  This seems a problem with legacy Cisco VPN clients because encryption card matches the entry VPN site-to-site, even if they use VPN clients.  A good/simple solution to solve this problem?

  Some newspapers (198.18.85.23) is the address public IP for the office and the tom.jones is the user.  192.168.1.0/24 is the pool of the VPN client.

  Hello

  Don't know if this will work, but you can try the following configuration (with the rest of the VPN configuration)

  list-access CLIENT VPN ip enable any 192.168.1.0 255.255.255.0

  card crypto OUTSIDE_map 4 is the VPN CLIENT address

  card crypto OUTSIDE_map 4 set peer 198.18.85.23

  card crypto OUTSIDE_map 4 set ikev1 transform-set ESP-AES-128-SHA ESP-3DES-SHA

  The idea would be to have the ACL matches the VPN full Tunnel that the Client attempts to establish. (destination "any" from the point of view of the customer, the ASAs view source)

  I tested briefly on my own SAA by connecting from an IP address to which the ASA offers free VPN in L2L. But as I don't have the operational L2L VPN, I can't really verify the VPN L2L at the moment. Thus, certain risks may be involved if you can afford it.

• Restrict it to certain IP addresses for establishing IPSec

  Is it possible on Cisco ASA 55xx to limit (filter) some public IP addresses that would be THE ONLY book able to establish remote access IPSec VPN using the Cisco VPN client? Suppose that Cisco VPN client establishes the VPN public IP (always the same) fixed.

  So, I do not speak about the actions of the ACL on the VPN traffic. I wonder about the IPSec tunnel creation and prevent certain public IPs to even try it.

  Thank you.

  Hello Ivan,.

  You can use the access-list control-plan to filter to the ASA VPN connections by blocking UDP 500.

  For example:

  ciscoasa (config) #-access VPN-FILTER list deny udp host host eq 500

  ciscoasa (config) #-FILTER-VPN ip access list allow a whole

  ciscoasa (config) # access - group FILTER-VPN in interface out-of- control plan

  Kind regards.

• VPN provider that allows only public IP addresses

  I need to establish a VPN to a seller who will only allow the public IP address through a VPN.  I need to keep the public IP address of my local network for the safety of political reasons.  I use an ASA 5510 with 8.2 (1) which is connected to a port DMZ on my router 3845.  My main firewall is configured on this router 3845.  ASA firewall does not have its own outside sepereate internet connection a 3845 router/firewall.

  This questions is connect the server of the provider (public IP) to my internal server (IP address of RCF - 1918) without having to put to rout the public IP address on my local network. Now, my only solution is to try a double NAT on the router DMZ and ASA at the moment.

  Ideas?

  OK, then you need to configure static NAT.

  You already have a static NAT configured for your internal server?

  If this isn't the case, then simply create static NAT with ACL as follows:

  static-server host ip access list permit

  public static static-server of access (inside, outside) list

  For the crypto ACL:

  Crypto-acl access-list allowed host ip

• Access to the COR to two XP systems behind a router with a single public IP address

  Hello

  is it possible to access the RDC to two XP systems, with two different port for the DRC, behind a router with a single public IP address?

  Please note this ia a small home network without any parameters of the field. I use IP to access DRC.

  You comments are appreciated.

  Thank you

  Use different ports for the DRC on both XP and configure the router to redirect to the appropriate port on the appropriate computer.

• Deployment of ESA without public IP address

  Hello Experts,

  I want to know that if I deploy ESA in my network without public IP address with a config on the SAA as if is there any traffic to port 25, then transmits to the ESA to the Exchange.

  I published the public IP address of my firewall in the MX record.

  In this scenario, there will be no problem for the ESA to determine the reputation of the sender when you receive an email?

  And if ESA is not able to determine the reputation of the sender, then, what is the best way to deploy the ESA without using a public IP address.

  I know that 99% of the ESA facilities use a private IP address on the public static listener with NAT on the firewall in front of the ESA. There is nothing wrong with that. Just think that get translated here. This is the destination IP address of the request that comes from the internet and ESA can still see the IP address of the sender. Only your internal mail server does not see the sender-original INVESTIGATION period. But there's nothing in general not as SPAM-check is done, when the mail strikes the internal server.

• Site to Site VPN between ISR4331(Data Center) and 25 branches with RV042 and dynamic public IP address

  Hi, we just got router ISR4331. We will use this router to our datacenter as pummel hub. Not to mention that it will be the static IP address. Our goal is to connect 30 small offices to the Datacenter by VPN site-to-site. All of our offices a RV042 router and DSL connection, so dynamic public IP. How to accomplish this task.

• Could not ping router RV042G public Internet address when it is after spending a SG200-08

  I use the optical fiber Singtel broadband server. I installed a SG200-08 for UNTAG VLAN to port 2 and connect the port to port RV042G WAN 1. It works very well with a public IP address. Access to Internet is very well to router LAN ports.

  However, I try ping on the public IP address of RV042G of the internet, I could not reach him. Everything what I'm missing in configuration SG200-08?
