External access to a single server Via VPN

Hello

I borrowed from a router (878) customers using the VPN Client, they can access what they need in their own country.

A new requirment has developed, there is a hosted server that has IP restrictions so that only a range of internal addresses can be accessed.

The question is when the VPN client is connected and it picks up an internal address, how do I allow access of an upside to a host. I had thought of split tunneling, but the connection must come from the internal lan and in this case, this does not seem that it will work. There is that a single Internet connection, there is no proxy internally I could use.

Will this work? If Yes, what is the best way to solve this problem.

Thank you

I'll have to look my docs, but I'm sure that I have an example... in any case, here's some info

Do split tunneling and enter this pool to server traffic to that

then your outside I based source direct all traffic pool ip to ip loopback public server using the command set routing interface

and then classify this internal closure in making ip nat inside for something of this interface will be natted / patted your ip of the interface and now your server he will recognize

hope this helps

Access PIX NIC canoe internal via VPN

Hello

We have a customer with a PIX 515 we installed and we have a private network virtual of our office to them. We communicate to all their guests behind the PIX over the good VPN configuration (telnet) and monitoring (SNMP). We want to control the PIX via snmp as well. We are unable to access the internal ip address of the NIC through the VPN. We can not ping, telnet or use SNMP to it.

The VPN works great as I said above, but is there anything else I need to do to allow access to the internal IP of NIC address?

This is the normal behavior of Pix. You cannot communicate with a Pix interface unless it's the only one to receive the traffic. Therefore, you can monitor and communicate with the outside/IP of the Pix from the Web interface.

BTW... This changed in Pix v6.3 that came out yesterday. You can use the command [management-access] to manage your Pix using his IP address private through a VPN tunnel.

Access for interal AND external users through a single login server?

Hey,.
Apart from redundancy, it is possible to have a single connection server that allows internal users AND external access virtual resources?
For external access, I have associated my login server security server. It works perfectly if I activate the PCoIP Secure Gateway option on my server of connection and enter the public IP address of the Security server.
But with this configuration internal users are not able to connect (listing the works of resources, but the connection fails).
If I disable the PCoIP Secure Gateway option, internal users can access, but not external users via the Security server.
Any contribution is appreciated.
Thank you very much!

No, it's the only way you can do it for internal users and external to share the same login server - activation of the MTP setting is by CS. If you want to PSG on for external users (and it is practically a necessity unless you use a third-party VPN), but offshore for internal users, they will point to the servers of different connection and so you'll need two.

Customer remote cannot access the server LAN via VPN

Hi friends,

I'm a new palyer in ASA.

My business is small. We need to the LAN via VPN remote client access server.

I have an ASA5510 with version 7.0. I have configured remote access VPN and it can establish the tunnel with success. But I can not access the server.

Client VPN is 5.0.07.0290 version. Encrypted packages have increased but the decrypted packet is 0 in the VPN client statistics, after I connected successfully.

Next to the ASA, I show crypto ipsec sa, just deciphering the packets increase.

Who can help me?

Thank you very much.

If a PC with a DHCP server is connected via VPN, with her serve IP addresses on the tunnel?

Situation: we have a few portable computers test Ubuntu running DHCP servers. We need get the updates and other changes in corporate network sometimes. Today, we turn off the DHCP server, set up to get an IP via DHCP (besides) and make our updates.

Problem: we do not want someone accidentally connect the laptop to the corporate network, while its DHCP server is running.

Question: so, if we go via wifi using a Cisco VPN client, the DHCP server IP addresses above the tunnel?

Thanks for reading.

N ° DHCP uses layer 2 broadcasts to disseminate IP addresses. Because your clients are connected via VPN, there is no contiguity of layer 2. The only way he would accidentally do it is if you have configured an address to support IP dhcp as one of your VPN clients on the network, which I imagine you wouldn't.

Unable to access company LAN via VPN

Hello

I have an ASA 5505 that I used to test run them the IPSec VPN connection after having studied the different configs and crossing the ASDM I get the same question that I can not receive any traffic.

The company LAN is on a 10.8.0.0 255.255.0.0 network, I placed the VPN clients in 192.168.10.0 255.255.255.0 network, 192 clients may not speak on the 10.8 network.

On the Cisco VPN client, I see a lot of packets sent but no receipt.

I think it could be to do with NAT, but the examples I've seen I think it should work.

I have attached the complete running-config, I might well have missed something.

Thanks a lot for all the help on this...

As you can see, I have create a new pool, since you already have an interface in the 192.168.10.0/24 network, which affects VPN clients.

Once you have finished, connect the client and try:

Ping 10.8.127.200

It work?

Try to ping so another internal IP.

Let me know how it goes.

Programmatic access to remote files via VPN on Playbook

Hello

It is technically possible to download remote files via VPN programmatically?

I can't find any documentation on this topic.

Thank you

Oh, not... I don't think it's possible.

R12 external access
Hi Hussein.

In my test env, I have one instance of single node of R12 (12.0.6) running on RHEL 5.3. This instance environment is encapsulated in a VPN. I want to give access to the instance of R12 to some users for the test that are not the VPN (via the internet). I want to build a test environment to learn the DMZ. R12 is configured using a dummy test to the test instance domain by adding entries in the hosts file on the server but also in-house client-side. I have no balancing requirement at this point because it is only for the test.

I just want to build a very simple configuration with minimum additional HW/SW that can meet my requirement above. Please help me with the following. Step by step instructions or guide will be really appreciated.

http://R12.West.domain.com - current URL for VPN access
http://R12.Domaon.com - proposed URL for external access

Need me a separate server outside VPN.
How need additional IPs public and private (VPN).
Do I need to have a Public domain.
Do I need to have any component of network as a switch/router.
Any additional software component must be installed.

I got the following note for 11i from your previous post that I don't have the chance to implement that I updated the instance of R12.

Note: 287176.1 - Configuration of the DMZ with Oracle E-Business Suite 11i

Please suggest/Advisor.

Thank you

Samar,

This document is not about this option in detail because it is covered with some other document.

CUPS, Jabber IM for iPhone, Mobile and external access

Hello world

How do you provide external secure access for email Instant Jabber for iPhone client and the Cisco Mobile customer on an iPhone?

There are so-called security SSL for Jabber Instant Messaging, but is unable to find all the information on how. The Cisco Mobile client appears to the needs of the AnyConnect VPN client and encourage users to connect via VPN, first...

After a bit of bumping into a wall your head wondering why there was no documentation for external access to Cisco Jabber for iPhone, I realized that Cisco Jabber IM for iPhone is an entirely different product and Jabber for iPhone seems to be the new name of Cisco Mobile customers. Yet, the only documentation I can find for the Jabber Instant Messaging is that I can "security by using the Secure Sockets Layer (SSL) encryption" but no information on implimenting it with CUPS.

On top of that, the Jabber IM for iPhone can not make calls but rather calls Cisco Mobile, which raises the question of providing external access to this too, and the only solution I've ever found is to use the AnyConnect VPN client on the device also. Suddenly, it seems to offer a solution of Cisco Unified Communications on an iPhone, I need three different and is applications is no longer quite as unified.

Thank you

Mark

Conclusions you drew on the product names are correct. They are transitioning to Jabber like a brand name, but it did not in the iOS VoIP client yet. The most recent Cisco Jabber for Android is the first to include Secure Connect (remote access protected or ensure access transparent, aka). The BU seems characteristic knocking out on a single platform and then replicating them on others before moving on to the next batch of features. I don't have a specific timetable to share but expect customers to iOS updated in the coming months with Secure Connect.

With regard to the separate clients: I can see both sides of this room. The more I use them more, I agree with the decision to keep them separated and cross-launch when necessary. If you think it is consistent with the way the user interacts already with their phone: voice and texting are two separate applications. I suspect that the developers also get some benefits by keeping things more targeted (e.g. less than test whenever they change something). The only downside to this approach is that each app consumes its own tunnel AnyConnect on the SAA.

(RV220W) Help! How can I access with my FileZilla Server?

Hi everyone - please help a noob of network configuration! :-)

I want to share files with people, so I downloaded server software package of FileZilla (free) and now need to get my RV220W router to allow the traffic to this server... and because of my limited understanding of how it all works together, I am currently blocked.

So if someone could guide me a bit, it would be really great! I read a few responses from people on port forwarding, but cannot operate in my situation... and probably because I did not understand how the communication happens... like which ports go where and what IP address should be linked to another, etc..

Here's what I know though:

FileZilla server - IP 127.0.0.1/port 21 + username + psw

RV220W router IP 192.168.1.1

My "external IP" = 37.75.XXX.XXX

More info needed?

Now, should what I do, in order to let the other access my server via a klient FTP FileZilla? :-)

Oh and I'm using the latest version of firmware RV220W (menu seems reorganized between some versions).

Input greatly appreciated! :-)

You must go to the firewall section (sometimes called security) the router and set up a rule to access the IP address of ANY side ALLOW WAN to the local IP address of the FTP server. Then go to transfer port (sometimes called Apps and games on some routers) and set up a single port forward port 21 to the local IP address of the FTP server. The 127.0.0.1 address you stated is the Local host, which is not the IP of your server network. Go to the command line and run ' ipconfig / has "without the quotes. Find your ethernet interface, and it will tell you the IP address assigned. You might have to configure this server with a static IP address either by making a reservation in DHCP from the router, or to go in your server network connection properties and there to under TCP/IPv4 properties. This way your server will not change IP addresses when the DHCP lease runs out.

I hope this helps...

Cannot connect remotely via VPN since installing the new modem/router

Can anyone help please. Since the acquisition of a new router / modem I can no longer connect via VPN to my work PC remotely. It comes in I receive the error message. Can someone tell me if I need to change the settings for the new modem / router to access?

Hello Joanna,

Here are the steps you need to do first:
1. Off static IP for my server and let the router assign IP address and changed the IP address of the port forward.
2. Check the IP address because obviously, that changed when you plugged into the router again.
3. Updated to the latest firmware for the router and NIC.
For more detailed troubleshooting you can refer to this link: troubleshooting common VPN related errors.

Let us know how it goes.

Traffic of Client VPN routing via VPN Site to Site

Hello

We have the following scenario:

Office (192.168.2.x)
Data Center (212.64.x.x)
Home workers (192.168.2.x) (scope DHCP is in the office subnet)

Connections:

Desktop to Data Center traffic is routed through a Site at IPSec VPN, which works very well.
Welcome to the office is routed through a Site IPSec VPN Client.

The question we have right now, is the Client VPN works, and we have implemented a split tunnel which includes only the subnet of the Office for a list of network.

What I have to do, is to route all traffic to home' to 'Data Center' by site to Site VPN is configured.

I tried to add the ranges of IP data center to the list of Client VPN Split tunnel, but when I do that and try to connect at home, I just get a "connection timed out" or denied, as if she was protected by a firewall?

Could you please let me know what I missed?

Result of the command: "show running-config"

Access to services: conflict NAT and VPN

Hi people!

I encountered a problem with external access to local services of:
(a) remote clients (port open on the side WAN)
(b) the remote sites (through IPsec tunnels)

Here's a topology:

EXPLANATIONS

FW1 (actually from TMG 2010) overload NAT of preforms.

The service in question (for example tcp 9999) is published on 192.168.100.0/24 via static NAT translation, which is accessible from the network.

HQ1 is a border router (cisco 2921). It also performs NAT overload for public addresses. (Other than cisco) Branch1 also performs NAT overload.

All traffic between the headquarters and the remote site is allowed. The service is accessible from the remote site.

PROBLEM

I want to allow access to the service for an external user (remote user). I do the following configuration:

IP nat inside source static tcp 192.168.100.2 2.2.2.2 9999 9999 extensible

After this command remote user is able to access the service by public IP, BUT the site's users remote losing it. If I roll back with

No nat ip inside the source static tcp 192.168.100.2 2.2.2.2 9999 9999 extensible

then access to the remote site is restored, and remote user lose again. Seems that it is connected with the static NAT translations.

How can I make it work in both cases of simulteniously? Both for the remote site and the remote user.

Thank you!

You must use a map of the route with your static NAT configuration.

After moving to Windows server 2012 VPN connection error

Hello world!

Recently, I upgraded my Windows Server 2003 SB server to a new server running Windows Server 2012.

I started from scratch by creating a new domain, user, accounts etc.

The new server is using the same IP address as the old server.

Since then, I can't connect through the VPN. I have already added the role of remote access on the new server.

When I try to connect to my Windows 7 laptop, I get this error:

"Error 800: the remote connection does not because attempts VPN tunnels failed." The VPN server is maybe inaccessible. "If this connection tries to use an L2TP/IPsec tunnel, the security settings required for IPsec negotiation is may not configured properly."

Any help with this is appreciated.

Hello

The question you posted would be better suited in the TechNet Forums. We have a separate team working on the server problem, so I would recommend posting your query in the TechNet Forums.

Security and restricting access to an FTP server

I did a search here on the forums about this and I wasn't able to find a good topic for my questions yet, if there is a debate currently on the forum, please forgive me and I would be grateful for a link. Anyway, my situation:

I have an ASA firewall and I have never set up an FTP server for a large-scale network (good in my opinion). I want to ensure that we have the highest security level optimal for FTP and restrict only specific users designated by an ACL. SFTP would be the best option available for the security measures? Should I only use the passive FTP mode and range of ports above 1023 do I open for only 1 or 2 FTP clients at a time? Also if I use passive mode do I need to use FTP protocol control?

In addition, currently, I'm not sure what files need to be available on our network, but the SFTP server always must be installed in the demilitarized zone?

Thanks for any advice,-Mark

To activate the SFTP-server on the computer where the data resides is easy, but far not the safest option.

There are a few more ways to better ensure that. What about:

-Place the SFTP-server in the DMZ and let this server access the internal server via a fileshare. If someone takes your SFTP server, so it cannot directly a system in the internal network under its control.

-If the data display, data cannot be copied or synchronized to the DMZ-SFTP-server once the changes.

SFTP is based on SSH, so it works entirely on a port which is usually TCP/22.
