Still do not get NAT to work, please help!
Hi all
I'm distraught after trying a large number of configuration settings in order to be NAT'ing on VMWare server (2) to operate.
I have a host and a guest (VM) running Ubuntu Linux.
I want to be able to reach my guestVM from the outside world by using the IP address of my physical machine, port X. A service is listening on this virtual machine, on the port Y.
What I currently have is the following:
Iptables on physical host (a few large lines of it):
echo 1 & gt; / proc/sys/net/ipv4/ip_forward
iptables Pei FALLING forward
iptables - A PREROUTING nat t-i eth0 Pei tcp - dport X-j DNAT - destination 192.168.6.3:X
iptables-a FORWARD eth0 o vmnet8 Pei tcp - dport X-j ACCEPT-i
A few large lines of /etc/vmware/vmnet8/nat/nat.conf:
& lt; host & gt;
IP = 192.168.6.2
subnet mask = 255.255.255.0
& lt; incomingtcp & gt;
X = 192.168.6.3:Y
The guest's IP 192.168.6.3
I restarted VMware (/etc/init.d/vmware restart) for the configuration to take effect.
Because I so read in a message, I activated the redirection ipv4 on the guest (but also tried without redirection enabled on the host).
From the reviews, I did not any configuration of iptables so far (so default settings apply).
I can see that packets are not have filtered in my iptables on the host, because at the end of the config script, I make sure that everything I have not configured to let pass will be saved before he fell.
In addition, it is important to note that with this configuration, redirect works correctly when I try to use the service on the guest VM, initiated from the host.
When I try to connect to the service of the VM guest from outside, I can not connect. Packets only to the service.
Can we see one any error in my thinking/configuration?
As I said, I'm quite distraught after all my attempts so far.
Best regards
Tim
Welcome to the forums!
Do not use and the iptables rules for the transmission of packets to the guest. It is matter of VMware.
Temporarily disable all firewall rules (iptbles - F) and test if it works. If it works just use your normal rules to protect the physical network of tzhe port. If necessary, create a rule that allows the port X enter the host.

socket InputStream does not get all the data, please help
I've been doing stuff of network on blackberry for quite awhile, but still using the http connection.
I have to use the socket for a piece of my application connection, but could not do the work.
This code is what I do
String url =
"socket: / / ' + rmserver + ': ' + rmport;
Socket SocketConnection = Connector.open (url) (SocketConnection);
socket.setSocketOption (SocketConnection.KEEPALIVE, 1);
OutputStream = socket.openOutputStream ();
InputStream = socket.openInputStream ();
send something here using outputstream
int
If (f > 0) {}
do somwthing
}
AV is always 0.
I don't know that my server sends data successfully. I run the network packet capture tool etheal on the MDS Server, I can see given reached MDS Server, but they never come to my device app.
The outputstream works very well, I can send data from my application and my server code gets all of them.
Where should I check? If it is http, I can turn on the debugging http on MDS log and see all network traffic, but for the socket connection, data packet is not connected (or I missed where it is).
Is someone can you please tell me where I should go to understand why?
Please try the suggestion to remove the check mark on InputStream.available.

Cannot get SMTP to work, please help.
Hello
I recently bought the camera WVC80N.
The main reason I bought it was to receive alerts of request sent to me.
I have tried all the different combinations for a week and still no TEST EMAIL failed.
Here are my specs:
ISP: Verizon FiOS
I have a setup of router D-link N as an access point that connects to my FiOS router/modem.
The camera connected to the wireless D-Link router.
I tried my ISP's SMTP settings,
I have Verizon email through Yahoo!, so I also tried these parameters.
I made an GMX account and tried, without success.
Can someone please give me an idea on how to get this working?
Thank you!
Port 25 is currently being sent to the IP address of my camera.
Here's how I have my smtp on the camera settings:
From:[email protected]
SMTP server: outgoing.yahoo.verizon.net (I also tried outgoing.verizon.net)
Port: 587 (also tried 25)
My server requires authentication: checked
Username [email protected]
password: *.

Satellite A210-19Z: could not get internet to work with Windows XP installed
Hello
When I install Windows XP on my Satellite I can not get Internet to work
Do I have to install drivers or so?
Please post links to the drivers if so.Christian
Of course you need readers.
If you have connected your router with a LAN cable, then you will need to install the LAN driver. If you want to use the network WiFi WLan driver must be installed also.
If your computer laptop doesn t supports the WLan card then the WLan driver is not requiredAll the drivers (if available) XP can be downloaded from the European driver Toshiba page!

Good luck, you need technical support for a real computer store or system manufacturer is supported.
Your router could be suspicious here, you have successfully updated its firmware as a possible solution? And I would like to
Update your WiFi drivers on computers. How you are positioned in the router? Are there
obstacles in the path?Actually try updating your driver and disabling the network logon. You can download these on another
computer if you need to and transfer on removable media.Control Panel - network - write down of the brand and the model of the Wifi - double click top - tab of the driver - write
version - click the driver update (cannot do something that MS is far behind the pilots of certification). Then
Right click on the Wifi device and UNINSTALL - Reboot - it will refresh the driver stack.Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

http://www.Vistax64.com/tutorials/193584-Device-Manager-install-driver.htmlDownload - SAVE - go where you put it - right click – RUN AS ADMIN.
You can download several at once however restart after the installation of each of them.
After watching the system manufacturer, you can check the manufacturer of the device an even newer version. (The
manufacturer of system become your backup policies).Repeat for card (NIC) network and is a good time to get the other updated drivers as Vista like
updated drivers.I would also turn off auto update for the drivers. If the updates Windows suggests a just HIDE as they
are almost always old, and you can search drivers manually as needed.How to disable automatic driver Installation in Windows Vista - drivers

Make sure you know the details of connection to your wireless router - SSID and password.
You lose connection when you do and have to redo your logon.
Control Panel - Network & Sharing Center - right, click Customize - page set of network locations.
lower left click on merge or delete network locations - REMOVE all instances of your network (and the
others you don't use anymore) - REBOOT. Start - Connect To log on to the network.-----------------------------------------------------
