internal hosts cannot access the internet w / L2L configured tunnel
The internal hosts behind the ASA cannot access the internet with a configured tunnel to L2L. The L2L tunnel is mounted and passing traffic correctly. However, the internal host cannot access the internet through the ASA. I think I have my NAT watered somewhere. I can't even a host statically mapped to the internet. It might be because I'm used to having a WAN IP to the external interface which differs by the CIDR block assigned by the ISP. In this case, it's all together, with the ASA outside interface occupying the first available address.
We have been assigned a CIDR range x.x.x.64/28. x.x.x.65 is my front door and my first usable est.68, by the PSI (I guess what they utilisent.66 et.67 for internal use). External interface of the ASA est.68 and I'm trying to get NAT others. I'm Polo all DHCP clients internal and have some static entries as well. Below is the relevant NAT config. Yet once, all traffic passes above the tunnel properly, but not from inside to outside. If more information is needed, please advise.

Cannot access the internet with bridged network - Windows 7 64 bit host, XPSP3 comments
I use VMPlayer v3.0.1 build-227600 on a PC under Windows 7 64-bit. My guest operating system is Windows XP Professional w/SP3.
I read all the messages on the use of NAT for the guest operating system can access the internet. But when I do that my guest is unable to access my Oracle server on my network. If I use Bridged my guest can access my Oracle server, but it cannot access the internet! How can I fix it? Shouldn't VMPlayer allow the guest OS to access the network and the internet? I need these two features.
Any help would be appreciated.
the simplest solution would be to add a second NIC to your comments, so that you can have bridged and NAT at the same time

I understand that you are having a problem with your WiFi and wanted to help you!
You are trying to access WiFi through router? If you are connected to your wireless network, but cannot access the internet, then the problem may be with the router. Check that the router is connected to the internet. If you have more than one router, then you can ensure that you are connected to the correct router. You can also try unplugging the router for about 30 seconds, and then reconnecting it. Please consult the following document, as it can help solve the problem for you:

Cannot access the internet on a network Windows XP when Windows 7 goes to sleep
Original title: Windows 7 Windows XP network problem.
I replaced a Windows XP computer on my node 4 (2 PC, printer 2) cable network with a Windows 7 computer. When the Windows 7 computer in mode 'sleep' the other (XP) computer cannot access the internet. A message appears that there are 2 computers with the same IP address. If I wake the computer 7 fine. That is what it is? I agree not all files between the computers.
Hello
It is usually the case when, for example, a router is off, but one or more of the devices connected to the router are left on.
The devices to retain the ip address assigned to them, but when the router starts up again it has no knowledge of this. If when you start one of the other devices, the router can assign an ip address already in use. Concrete example that I reproduced with my router and the PC...
- Start the router, then boot PC1 and PC2 - the router (192.168.1.1) will allocate for PC1 192.168.1.2 and 192.168.1.3 to PC2
- Turn off the router, then turn off PC2, restart and shut off again
- Put the PC1 to sleep
- Start the router and PC2, the router does not PC1 and allocate 192.168.1.2 to PC2
- PC1 to wake up and there still 192.168.1.2 who now is a confrontation with PC2
Other ways to reproduce this situation may also be possible.
All devices on your network must have a unique ip address, where the warning message.
If you get this situation once again, the solution is to turn off all devices, including the router, then restart the router, then restart all devices connected to the router.
To avoid this, you may be able to put ip Reservations for your router address which will ensure that all devices connected to the router always get the same ip address (unique). If you are unsure how to proceed, we will need your router brand and model to help.

I am faced with a kind of strange and unusual error. in my office, the internet is accessible with the proxy server. without him we cannot access the internet. However, there is a laptop computer on which some time the internet is accessible only when I leave the proxyserver only on that machine... any idea?
Hello
Work on a domain environment?
Changing the proxy settings is something that you usually only have to do if you connect to the Internet via a corporate network. By default, Internet Explorer automatically detects proxy settings. However, you may need to manually set a proxy with information supplied by your network administrator.
If you are on a domain environment then please post the question on the link mentioned below using:
