Pool of dhcp NAT VPN to the LAN on router 2911
I need nat the ips assigned by dhcp vpn to my LAN pool. My problem is that I do not know which interface to set my nat statement on since there is no interface that is in the same subnet as my dhcp pool. Any help would be appreciated.
For remote client ipsec, you must have DVTI according to configuration described here:
http://www.Cisco.com/en/us/docs/iOS/12_3t/12_3t14/feature/guide/gtIPSctm...
'use ip nat inside' on the virtual model and 'ip nat outside' on the inside of the interface.

CANNOT ACCESS THE LAN WITH THE EASY VPN CONFIGURATION
Hello
I configured easy vpn server in cisco 1905 SRI using ccp. The router is already configured with zone based firewall. With the help of vpn client I can reach only up to the internal interface of the router, but cannot access the LAN from my company. I need to change any configuration of ZBF since it is configured as "deny everything" from outside to inside? If so that all protocols should I match? Also is there any exemption of NAT for VPN clients? Please help me! Thanks in advance.
Please see my full configuration:

RVL200 error message: DHCP IP address range into conflict with the LAN IP address
I have a RVL200 (firmware v1.0.12). I use it mainly as a firewall, but also taking advantage of the DHCP server on this subject - at least I thought I was!
When I configured the RVL initially (several years ago), I have it has assigned an address 192.168.0.128 LAN IP and enabled the DHCP server. The DHCP address for the allocation range is 192.168.0.100-. 149. I have not assigned a DNS server address (don't remember why not - maybe - because of the same issue, I'm now face). Since then, whenever I have to appear a new PC on my LAN I put client PC using DHCP to get an IP address... but I need to manually specify the DNS server address (which is logical in the light of what I have described so far).
The question I have now is that I want to assign the DNS server address on the DHCP server on the tab Configuration RVL, so my client DHCP PCs will automatically resume the DNS server address. But when I enter the address of the local DNS (192.168.0.1), the RVL gives me the error message listed above (conflict IP range). I can't understand why...
The "strange thing" I see is the DHCP of the RVL / status tab - at the top of this tab it lists the DHCP server address is 192.168.0.1. This is the address of my DNS server / domain controller. And the IP address of the domain controller is assigned statically (if it matters). So I do not know why the RVL shows the DHCP server or my DNS server / DC, rather than showing his own address de.128. Or why I get this error message when I try to enter the address of the DNS server? Just as an experiment, I also tried entering the other IP addresses, just to see what happens (all on the local subnet)... and they all return the same error message.
Any ideas?
Thanks in advance.
Adam
1. the address LAN IP of the RVL shouldn't be in the DHCP address pool. I guess that causes the error message when you try to change the settings for the DHCP server.
2. I would say that you Flash the latest firmware 1.1.7 on your router. Read the release notes.

Cisco 877 site to site VPN routers a DHCP end cannot get the tunnel
Hello
I have two 877 cisco routers with the static ip address and other (3 routers more) with ADSL DHCP using the no - IP.com.
Currently I'm doing tests with only the static IP router and a DHCP router.
I can't go up the tunnel and running, I can connect using Cisco VPN client, but a site that is the most important of them does not work
I followed the example of configuration on this document http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a00801dddbb.shtml
But I have no session encryption of output as well as no ipsec or isakmp output using this command (it's on the static IP router)
SH crypto ipsec his
Crypto isakmp HS her
SH encryption session
on the dynamic ip on the router side, I exit that with the sh command its crypto ipsec
This is the output

Use the client VPN tunnel to cross the LAN-to-LAN tunnel
I have been troubleshooting an issue and cannot cross an obstacle. The ASA is running ASA running 1,0000 code 24. I am using a client VPN tunnel to connect to the ASA. The ASA has already a LAN-to-LAN tunnel, set up and operating and I need the VPN client to access the remote site over the LAN-to-LAN tunnel.
The internal IP address of the local part is 192.168.0.0/24 and the IP address of the Remote LAN-to-LAN tunnel is 172.20.1.0/24. The clients are distributed 192.168.200.0/24 IPs. I have attached the relevant configuration for the SAA.
When the VPN client on the network, I can access resources on the ASA network internal. On the internal network of the SAA, users can access resources through the LAN-to-LAN tunnel. Client VPN cannot access resources on the LAN-to-LAN tunnel. For the latter, there are no hits on the C-TEST access list.
Thank you for your help.

Remote VPN - no remote LAN connectivity
Hi all
I'm having a problem with my remote access VPN to home. I have a router 800 series which is serves as the VPN (this is also my ADSL router modem), and there isn't enough work as it should...
I can establish a connection to the outside world, and when I run show crypto isakmp/ipsec his I see relevant entries. However, my problem is that once connected, I cannot ping anything in my local network. I can't ping even inside my ADSL router interface. I have another 800 series which is the next leap in broadcasting wireless clients, and is not accessible by ICMP either when it is connected through the VPN.
I won't go through all the troubleshooting steps that I've taken the case, this post will be a saga. I guess it's a routing problem or a NAT? It is not all NAT entries for the VPN client when it is connected, so I think that I bypassed that correctly.
I stripped my config back a bit just to try to make it work, I've pasted below:

endWell, if you see encrypted/decrypted packets move away a lot of problems.
You can TEST inside the router of the VPN Client (LAN) IP?
This local network should have a default gateway pointing to the router or a route from the pool of VPN.

VPN IPSec in LAN-2LAN tunnel configuration
Hi all!!
I'll put up a tunnel between a cisco 1841 router and a VPN 3000 Concentrator LAN LAN 2 ipsec.
Here is running for the router configuration and basically what I want to know is to ensure that I put everything in place to do this work. So can you please take a look and see if you find something a little odd and if so let me know!

Thank you very much in advance for your help
Glenn
Thanks for the configuration.
So you're natting and then to encrypt traffic natted. Which is totally fine. The reason, your ping does not work after the application of cryptography is due to the ACL entries below:
access-list 101 permit icmp any any echo
access-list 101 permit icmp any any echo response
The acl entries above are part of the traffic interesting Crypto. So once you apply the card encryption the router is supposed to encrypt all ICMP Echo and Echo-Reply, including traffic that is presented with the ip address of your 201.x.x.x. If you remove these two entries of the ACL 101 and apply only the below entries, then the ICMP should work with the applied crypto map.
access-list 101 permit ip 172.4.4.0 0.0.0.255 172.17.0.64 0.0.0.7
access-list 101 permit tcp host 172.4.4.5 host 172.17.0.65 eq 1000
access-list 101 permit udp host 172.4.4.5 host 172.17.0.65 eq 1000
After making the changes, make sure that crypto acl is images mirror on VPN3000 and router, or otherwise you will have problems in the implementation of the tunnel.
I would like to know how the test goes without the ACL 101 ICMP entries.
Kind regards

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.

Can't access mailserver when the LAN!
Hello.
I just install an Apple Airport Extreme (model Tower) as DHCP incoming WAN and one LAN out to a switch for the rest of the House/LAN connection.
But after the addition of the AE to my network, that I am more able to access my Synology mail server messaging, when I am connected to the local network. But if I use my iPhone on LTE, there is no problem!
I used the router configuration configuration option on my DS-214se, to configure the DS with the AE.
Someone has any ideas why this happened? I think that I have heard something about the closure of NAT, but I'm
not sure if this is the problem and I do not see any where to set Nat Loopback on EI.
Kind regards
Stone.

By "DHCP" do you mean you have set up the AirPort Extreme to use router Mode = DHCP only? What is the brand and model of the device that is connected to the WAN port on the extreme?

WRT54GL cannot transmit from inside the LAN port?
Hello
I have a Server servers running several (HTTP, SVN, FTP,...) inside my network.
I used to have a SMC router in the past, and of course I had to use port forwarding.
This is why I realized that when we "talk" to the server, I can 'talk' to the router that will forward requests to the right compurer, based on the NAT table. If, for example, that if I move the SVN server, I don't have to change the path to the repository, change the NAT entry is OK in this case.
If this is not understandable, here 's another report.
However, I discovered that even if my new WRT54GL seems to be much more advanced, it cannot do this. Requests made to the router from within the local network are not transferred to the right place.
Is there a way to accomplish what we need, or at least a road map? It's sad that the SMC products otherwise is not very reliable can do...
Kind regards
Matej
Well, I have it solved.
I tried to convey the SVN, HTTP, FTP, and SSH.
However, it was not working when the server IP assigned by DHCP.
When I set up (the server within the LAN) to use the static IP address, not only that port forwarding began to make sense, but I have seen web pages by typing my public IP address in the browser on a computer inside the LAN.
What surprised me, is that it only worked when the server had assigned auto private IP address. I know that these addresses change so it would not very long work, but it did not work even before that t has changed...

QuickVPN connected, but I can't do anything on the LAN ping
Hi all
I try to use QuickVPN to connect to my corporate network. Yesterday I was to the point where QuickVPN actually connected and I could connect to the router from inside IP. But I can't see, or ping all computers on the LAN to company. Manual of the router says '' customer QuickVPN may access only the default LAN hosts. ''. Are the computers of the default of the company LAN LAN hosts?
I added the router (RV220W) to the existing company LAN to test QuickVPN. The company LAN has a Small Business Server as a DHCP server and another router as the default gateway. The company LAN the subnet 192.168.1.0/24*, the cisco wan router has the subnet 192.168.103.0/24 and my VPN client is connected to a hotspot wifi with the same wan and LAN 192.168.3.0/24. The LAN of the cisco router address is 192.168.1.1.
* I know now, 192.168.1.0/24 is the worst possible choice for a net business, but I didn't when I installed the Small Business Server. I'll try to change it to something like 10.123.45.0/24 later.
Thanks in advance
Mike
Hello
You can reach a PC in the LAN of RV220, because the default gateway is not RV220.
This is what happens: the PC with fast VPN (for example IP: 192.168.103.10) is ping a PC with IP 192.168.1.10, via the VPN tunnel. Once the request arrives at the 192.168.1.10 PC, this PC sends the response to its default gateway (because don't have a direct connection to the 192.168.103.X network). If the default gateway is RV220, he'll know that the response should be returned via the VPN tunnel to the customer, but if it's another machine, it will just drop the package.
In this case this another router (default gateway) must be configured with a static route, saying that subnet 192.168.103.x has as default gateway - 192.168.1.1 (RV220).
As long as the IP address of the VPN machine fast is the same, it's ok. But if you move this PC to another local network, you will have again the problem.
So if you plan to change the LAN IP of the fast VPN machine, I recommend using instead the Shrew VPN, where you can configure virtual IP on the client, that does not need to change.
Kind regards

NAT VPN tunnel and still access Internet traffic
Hello
Thank you in advance for any help you can provide.
I have a server with the IP 192.168.1.9 that needs to access a subnet remote from 192.168.50.0/24, through the Internet. However, before the server can access the remote subnet, the server IP must be NAT'ed to 10.1.0.1 because the VPN gateway remote (which is not under my control) allows access to other customers who have the same subnet address that we do on our local network.
We have a 2801 Cisco (running c2801-advsecurityk9 - mz.124 - 15.T9.bin) set up to make the NAT. It is the only gateway on our network.
I have configured the Cisco 2801 with the following statements of NAT and the relevant access lists:
access-list 106 allow host ip 192.168.1.9 192.168.50.0 0.0.0.255
NAT extended IP access list
refuse the host ip 192.168.1.9 192.168.50.0 0.0.0.255
deny ip 192.168.1.0 0.0.0.255 192.168.3.0 0.0.0.255
ip permit 192.168.1.0 0.0.0.255 anyroute allowed ISP 10 map
corresponds to the IP NATIP nat EMDVPN 10.1.0.1 pool 10.1.0.1 netmask 255.255.255.0
IP nat inside source list 106 pool EMDVPN
IP nat inside source map route ISP interface FastEthernet0/1 overloadWhen the server (192.168.1.9) attempts to ping on the subnet of 192.168.50.0/24 devices, the VPN tunnel is established successfully. However, after that, the server is no longer able to access the Internet because the NAT translation for 192.168.1.9 has changed since the external IP address of the router (FastEthernet0/1) at 10.1.0.1.
The documentation I've seen on the site of Cisco says that this type of Setup allows only host subnet communication. Internet access is not possible. However, maybe I missed something, or one of you experts can help me. Is it possible to configure the NAT router traffic destined to the VPN tunnel and still access the Internet by using the dynamic NAT on FastEthernet0/1?
Once again, thank you for any help you can give.
Alex

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.
