867 EasyVPN server: Intermittent client connectivity
I have a rather peculiar question with a particular router, which I use as an EasyVPN server.
Customers have no problem to connect to the router. The Cisco VPN Client connects without problems and without fail every time.
HOWEVER
This does not mean that the customer can obtain from the server, which is located behind the router, to which they connect.
They might be able to. They might not! It seems to vary randomly. Sometimes the client will connect, and the server will be accessible. Othertimes, the client will connect and it will not.
Now, to do some very preliminary tests, I am STILL able to ping the router LAN interface once the tunnel is up. However, I may or may not be able to ping the server.
Yesterday, for example, the connection came. I was able to ping an IP address on the local network of 192.168.0.9. The router is 192.168.0.15, I have, as mentioned above, ping without problem as well. However, the server, which is 192.168.0.1, was not accessible. After a couple disconnects / reconnect to the VPN client, I could ping 192.168.0.1 (and 192.168.0.15) and if I could get on the server without problem... However, I could no longer ping 192.168.0.9.
It almost feels "subnetty", but there is nothing defined on the router that should cause this problem I can say. Clients receive an IP address in the range of 10.10.10.5 to 10.10.10.15 on a looping with IP 10.10.10.1.
Specific no reason why the pool overlaps the closure? being a virtual interface should not make a difference on where the traffic is sent, the EFC plays sometimes strange games.
If it's not too much to ask, you can disable this loopack?

Bytes of TCP IP and subset of bytes for the connection of server and clients
Hello
I have a problem on the server and the client connection using the TCP/IP protocol. In the client, I have 41 cases, 1 case of timeout, others are for the case of button when they are pressed and then the LED on the server will be to market and if a click again the led will be off. But when I reached cases 10, 11, 12 up to the 41 (key case), that the LED lights if you click only once, but when he double clicked then the light does not turn off. So, how you solve the problem? Is this subset or bytes to read because the first subset is 1 case but no 10 to 41 will not work, but I change the subset in 2 then the case works for don't light the LED, but it do not work to turn the LED off.
I also download the vi in this for reference.
the user name for the client is the user and the password is pass.
Thank you
Hi ican.
you have not changed the customer. See the attached picture. The error in the server side, it's that the 4 was connected on the two functions of split to the length. See Server for the necessary difference image.

Web IR client server (0): database connection information is not available.
Hello
We have improved our system of Hyperion 9.3 to EMP 11.1.2.2. We use mainly the declarant a SQR production and interactive reporting tools.

Redirect server to client for certain file types.
Hello
I try Windows server 2012.
I'm testing RemoteApp through desktop Services remotely.
The software I use for my my tests is a customer of dynamic GP10.
So far, it works like a charm.
We have a plugin installed to easily produce lists (SmartList)
It allows users to export lists to excel. (It creates an excel file and try to open)
Question:
I want to transfer generated excel files to the remote client connected so it can be opened by its local installation of Microsoft excel.
Generally speaking, do something similar to the redirect print job to the printer of the client.
Is it possible to do?
I searched and found some interesting information, but still no easy way to do it.
I find many articles on XenApp and Citrix that might be able to do.
Of course, I could install MS Office on the server, but all my clients already have the OEM versions of Office installed so that we do not want to spend more money for licenses of office additional.
I did something similar many years ago with a virtual Windows XP Setup using vmware on a Mac OS x computer.
And with vmware, in this particular case, it was very easy to do.
Question:
It may be possible to do it with a script by using ASSOC and FTYPE commands.
I read the help page explaining the syntax ASSOC and FTYPE. But I am not able to understand what it takes to write my goal.
So, if it can be done this way, is there someone who could help me with how to build such a scrip?
Thank you

You must have an account set up under Tools | Accounts | Mail to send from Windows Mail. If you click on a link, it will not lead you to a webmail interface, but called instead a mail client, such as WinMail. Around that, the only way is to copy the email address and paste it into a new message you have composed of webmail.

Limits of pix 506 for VPN client connections
Hello. My company is looking to move away from using Microsoft's RRAS to workers to remote VPN connections. We have a 506th Pix currently serving 2 site VPN connections and client connections. Nobody knows what the limit for concurrent client vpn connections on a 506e and if having 10 to 20 clients connected at the same time (on a user base of 100 +) would cause problems. Any thoughts would be greatly appreciated.
There is no license for the number of connections limit, this is more a limitation of resources. Check that the data sheet a 506E can handle 16 MB of 3DES VPN. It's marketing plug so the actual throughput will be lower.
Hope that helps.

PIX: Cisco VPN Client connects but no routing
Hello
We have a Cisco PIX 515 with software 7.1 (2). He accepts Cisco VPN Client connections with no problems, but no routing does to internal networks directly connected to the PIX. For example, my PC is affected by the IP 172.16.2.57 and then ping does not respond to internal Windows server 172.16.0.12 or trying to RDP. The most irritating thing is that these attempts are recorded in the system log, but always ended with "SYN timeout", as follows:
2009-01-06 23:23:01 Local4.Info 217.15.42.214% 302013-6-PIX: built 3315917 for incoming TCP connections (172.16.2.57/1283) outside:172.16.2.57/1283 inside: ALAI2 / 3389 (ALAI2/3389)

We tried to activate and deactivate "nat-control", "permit same-security-traffic inter-interface" and "permit same-security-traffic intra-interface", but the results are the same: the VPN connection is successfully established, but remote clients cannot reach the internal servers.

I join all the details of the cryptographic algorithms because the VPN is successfully completed, as I said at the beginning. In addition, routing tables are irrelevant in my opinion, because the inaccessible hosts are directly connected to the internal LAN of the PIX 515.
Thank you very much.
can you confirm asa have NAT traversal allow otherwise, activate it in asa and vpn clients try again.

Hi all
I have a router with IOS advanced ip services 12.3.T3 1760 and it is configured as a hub dmvpn and it works very well and the rays work too. I want to know if it is possible to configure easy vpn server on the same router, and both services are running at the same time?
Concerning
Raul Hey how's it going?
The answer to your questions is Yes, remember that the server EzVPN configuration is like the configuration of the device for remote access VPN client.
I don't see why it does not work...
In fact, a Cisco IOS router can be configured as a server EzVPN & Client at the same time restrictions are for EzVPN client, it will be able to connect to a single server of EzVPN and nothing else.
Hope this helps

VSpher client connection?
Hello
To make clear that I am a novice.
I installed, ESX5.1 (bare metal), [VCenter Server, VSphere Client and client VSphere Web]-> Windows 2008R2.
It is the second facility from scratch.
In my first attempt, when all them above were installed, when I tried to log in using VSphere client, I could use the AD ID and I think what he connecterd me to ESXi through VCenter.
In my second installation, I can connect via Vcenter using the Web client, using my username AD (ID of the administrator group). Everything works fine, I created data center and added ESXi.
However when I click on VSphere Client, it does not accept my AD account and it only accepts the ID of the root for ESXi
I don't know if this is what is supposed to happen?
So the questions:
1. in order to access ESXis using VSphere Client through VCentre, what should I do? I mentioned, that if I try to open a session using the client it does not accept AD ID
2. How can I use webclient and no client (via VCenter)
< added some information: I renamed localhost in ESX01 ESX and he joined the field in the context of troubleshooting and client NTP is configured on ESXi, not Windows 2008R2, but Jet lag is less than 30 seconds if not less >
As I said I am new, however I am giving the foregoing experience of logical explanations.
Thanks in advance.
Welcome to the communities...
I don't know if I understand your questions, I tried with my awakening in response to your questions
1. in order to access ESXis using VSphere Client through VCentre, what should I do? I mentioned, that if I try to open a session using the client it does not accept AD ID
You try to access your ESXi host or vCenter server by using AD ID?
However when I click on VSphere Client, it does not accept my AD account and it only accepts the ID of the root for ESXi
Have you checked that you access your vCenter and no ESXi host using vSphere Client?
vCenter is a management software that allows to manage ESXi host. WebClient is only available to manage vCenter server and NO ESXi host

Can number of concurrent VI client connections there be on VSphere 4.x?
Thank you
Prashant
Hello, Prashant-
It depends on your version of vSphere. By the maximum of Configuration docs, the maximum rates are:
vSphere 4.0 with 32-bit vCenter server: 15
vSphere 4.0 with 64-bit vCenter server: 30
vSphere 4.1 (vCenter works on 64 - bit): 100
The docs of Maximums:
vSphere 4.0: http://www.vmware.com/pdf/vsphere4/r40/vsp_40_config_max.pdf (see page 7)
vSphere 4.1: http://www.vmware.com/pdf/vsphere4/r41/vsp_41_config_max.pdf (see page 6)
Enjoy.

See Security Server and direct connection
I have a security server for my connections from the Internet. It works very well, accept when I activate "direct connection on the desktop. I found the following statement on this:
If you bypass the secure connection, the client must establish a direct communication of RDP to the virtual machine desktop RDP (port 3389).
That means I have to open 3389 (RDP) to the Internet if I want to use direct connections?
If I disable the direct connections to get my security server doesn't work, I have to turn off on my login server. It is I understand that this means that if I reboot my connection to the server, all disconnected mode clients. Is there a way I can disable "Direct connections" to the Security Server, allowing access from the LAN?
TIA.
For a long time I had to face the problem then I hope I'm he transmit correctly. Because you don't want to open 3389 to the internet, you must use indirect connections to the broker for users of security server connections. This means that all connections made outside the LAN will be handled by the Security server. If you need to restart the Security server that these connections were removed. If you need to restart the broker to connect to security services server should not drop all connections, the external web page would become unavailable unless you also have internal customers using this broker for connections to how it would be mandated by the broker for connections and would be deleted.
Simple solution is to have a dedicated connection, broker for the Security server that is configured in indirect mode and then have one or two brokers connection for internal users who are configured in direct connection mode. As I have said for a long time I had to deal with this so please forgive me if I have nothing hidden.

VMware Client connection to a private internal network
I'm looking for a solution for my VMware based configuration please.
My Server 2003 host has a public and private address
My Server 2003 Client has a public and private address
The problem is that the Server Client cannot connect to the internal private network or even ping the gateway, only the public IP and the Internet work. The host has no problem, it connects fine to the gateways both Public and private.
The host uses a private IP, subnet mask, and gateway No.. Also a persistent gateway and IP, mask, DG entered. The public IP address has an IP address, subnet mask and gateway.
The Client is configured in the same way, but with different IP addresses on the same subnet as the persistent route have been added as host.
I tried a lot of things with vmnet0, vmnet1 and vmnet8 but had no luck.
R
Best with the attachment
Let as host only vmnet1 and vmnet8 as NAT. If vmnet0 is for one of the phyical NIC you want to fill then set VMnet2 to the bridge to the other physical NETWORK adapter so that you can configure your virtual machine to use vmnet0 or vmnet2 according to NIC's to the private LAN.
Also check that the VMware bypass Protocol is bound to the physical NICs that you want to be filled.
