Internal network segmentation using firewalls
Recently, an auditor suggested we should segment the internal network, including all professional applications, population office, internal messaging, remote access and the wan by using firewalls. Anyone done this? If yes why?
The concept of the demilitarized zone (DMZ) provides protection for senior level servers and applications etc. while allowing web servers and mail in general, access and the Internet. If the host is compromised, they do not provide an immediate springboard to important internal servers.
Of the resources of the company risk assessment will determine the level of required access control. Higher instances of compromise are always determined from internal sources and may justify measures of access control applied to the population of office according to the circumstances of the company and the security posture adopted.
See you soon,.
Paul.

[Q] create an internal network using Vmware 6.5
I have the following two images:
1 image: Ubuntu (Image)
NIC 1: connected in bridged mode.
NIC 2: I want this NETWORK adapter to be connected to a different network called "local".
Image 2: (NO OS installed, again)
NIC 1: I want this NETWORK adapter to be connected to a different network called 'local', and the MAC address is AABBCCDDEEFF
In VirtualBox I can connect to the internal network and name, I can also change the MAC address of the Vimage before it starts.
Is it possible to do using VMW 6.5?
Thank you very much
NIC 1: connected in bridged mode.
NIC 2: I want this NETWORK adapter to be connected to a different network called "local".
Use only the 'Home' network It is just a private network for virtual machines, and they can communicate with the host and other virtual machines connected to this network.
I suppose that the net result is that this specific virtual machine is a gateway to some form.
NIC 1: I want this NETWORK adapter to be connected to a different network called 'local', and the MAC address is AABBCCDDEEFF
So, the question will be if the NIC2 of an Image and NIC1 of two images are on the same network? If so, then just the NIC of Image value only two host as well.
If two Image must have it's own personal space, then you need to activate another host of the network alone. I think you can do this under the Publisher Network (Menu Edition or the Start Menu) and then activate a new network only host on a specific VMNet. Once you have a new network activate (say VMnet5), then the value of this "Custom" and the VMNet5 virtual machine NIC.
NOTE: The MAC address is generated the first time that a virtual machine is started after the creation, so it is not in conflict with other virtual machines on the same system. I wouldn't change it, but you can see in the VMX via Nano/VI or Notepad file.

I tried to go in advance and choose "Add TimeCapsule to the existing network", but it keeps defaulting to 'add a new network '.
without having to activate the internal networks?
"Add TimeCapsule to the existing network.
You cannot add a TC in an existing network, if there is.
You must configure the TC for the network.
It keeps default back to "add a new network.
So, it's OK... The TC is part of an existing network or makes a new.
You must connect to the TC network... either wireless or ethernet.
However, you can manually configure the TC simply plug ethernet for example.
See, cable using Time Capsule for Mac for backup only.
The same can be done for the wireless... but a TC is really the bad device for backups if you don't have a network... It's cheaper, faster and more reliable by using a USB key.

Whenever I have unplug my laptop, the message "your internal network card has been disabled to optimize battery life.". Lately, the message doesn't go away, even when I plug my laptop back in. When I move my cursor over the message, it is an icon of mouse 'pending' for me and I am unable to click on it. I believe that this is due to a virus or accidentally modify me a file, but I don't know which and I don't know how to get rid of this problem.
I knew it was a Dell and find out how to disable the message (which is supposed to appear), but do not know why, when you connect what you are disconnect, the message does not go far - she used to go? It seems to be a useful informational message and not an error message.
I can't seem to find information on your system on the Dell WEB site to check your network drivers, so I hope someone will have the magic bullet for your situation. There are the user forums on the Dell WEB site where you could ask your question to be read by all people of Dell.
If you think that malicious software might be involved, I would start with this:
Download, install, update and do a full scan with these free malware detection programs:
Malwarebytes (MMFA): http://malwarebytes.org/
SUPERAntiSpyware: (SAS): http://www.superantispyware.com/
They can be uninstalled later if you wish.
The scans by operating clean, then to solve any problems.
Do not guess what the problem might be - understand and resolve it. I need YOUR voice and the points for helpful answers and propose responses. I'm saving for a pony!

Cannot access internal network so AnyConnect SSL VPN, ASA 9.1 (6)
Hello Cisco community support,
I have a lab which consists of two virtual environments connected to a 3750-G switch that is connected to a 2901 router which is connected to an ASA 5512 - X which is connected to my ISP gateway. I configured SSL VPN using AnyConnect and can establish a VPN to the ASA from the outside but once connected, I can't access internal network resources or access the internet. My information network and ASA configuration is listed below. Thank you for any assistance you can offer.

Hi all
I have the following questions about the Site Site VPN using ASA 5510 and 5505
Scenerio is
1. we have five branches & headquarters
2. we want to establish a vpn between branches & Head Office (VPN from Site to Site)
3. all branches & head office using the same internal network (192.168.150.0 255.255.255.0)
My question is
How can I configure VPN site-to-site between branches & head office with the same internal network (192.168.150.0/24)
Please help me with the configuration steps & explanation
I have experience on setting up vpn site to site between branches with differnet internal network (for example: 192.168.1.0/24 and 192.168.2.0/24)

Internal network can not access the external IP
I recently installed a firewall 506e to include a new IP block for our external interface. Origionally we used a PIX 515 to do a larger block of the IP, but he has run out of space.
I have set up the new block on the 506e and tested out successfully connectivity. I am able to ping and connect to internal an external network computers, but the internal network will NOT connect. Pings or HTTP tries the deadline. Here is a sample of the config that is used:
access-list 101 permit tcp any host 207.219.xx.xx eq www
static (inside, outside) 207.219.xx.xx 192.168.0.65 netmask 255.255.255.255 0 0
Access-group 101 in external interface
Please note that the internal network is NOT going through this PIX to reach the outside world. Only the machines that use the new IP blocks use this PIX.
All internal addresses are 192.168.0.x, regardless of which is their default gateway.
Any help would be greatly appreciated

Can connect to the IPSec VPN, but can not see the internal network
I have several users that can connect to our rooms of ussing IPSec VPN on a 5505. I have a user who can connect, but cannot see the internal network. This user is using DSL with a speedstream 4100. However, I have another user with the same configuration that can connect and see the internal network. Newspapers in ASDM show the link, but do not seem to show any errors trying to access internal. Any help will be greatly appreciated. Thank you, Bill.

Can not reach the internal network on the VPN
Hello
So I've been setting up an ASA5510 to the best of my knowledge to allow the VPN to our internal network access and its riches. IPSEC is configured correctly.
When connected I get an IP address from the VPN subnet with success, but I can't reach all internal hosts (failed pings). Also, I noticed that my default gateway uses a VPN subnet IP address.
I have followed the guide Wizard and configuration Online but am still in the dark... it's all a bit new to me!
I'll post the config if you need to see.
Any help would be appreciated!
Hi, just a few things I noticed. What group are you testing with? The tunnel of split for the two groups should be a standard ACL, well it doesn't have to be, but it is generally. I suspect that it doesn't because the ACL is defined in the wrong direction. You can therefore remove the first line of the RemoteVPNAccess of the ACL or replace it with a standard ACL. I recommend using a standard ACL.
Also applies similarly to your nat not and inside the ACL, they should be allowing the subnets the to address of the pool. So you can delete the second line of the ACL sheep and ' inside_access_in access-list extended ip 10.10.200.0 allow 255.255.255.0 everything ' inside ACL.
Also any tunnel or use a tunnel of split ACL but not both and also try to remove the filter from vpn, we can get to that after we have connectivity.

VPN router to router with overlapping of internal networks
Hello Experts,
A small question. How to configure a VPN router to router with overlap in internal networks?
Two of my internal networks have ip address 192.168.10.0 and 192.168.10.0
No link or config will be appreciated. I searched but no luck.
Thank you
Randall

A server is now accessible from external network access using the IP and port in browser below http
http://x.x.x.x:8080For the same, we have configured (static NAT) port forwarding in cisco security 1905.
The application is also accessible via IP and the internal network port internal (ie. http://y.y.y.y:8080)
Is there a way I can configure my 1905 Cisco as well as internal network (ie. machine B) I can access the application using the IP and the public port and not with the IP address internal? From now on, I'm not able to do the same.
The current configurations are as follows:
access-list 1 permit y.y.y.0 0.0.0.255
IP nat inside source list 1 interface GigabitEthernet0/0 overload
IP nat inside source tcp static y.y.y.y 8080 interface GigabitEthernet0/0 8080Hello
You can try Domainless Nat.
no nat ip within the source list 1 interface GigabitEthernet0/0 overload
no nat inside source tcp ip static y.y.y.y 8080 interface GigabitEthernet0/0 8080int gig0/0
no nat inside ip

Unable to access an internal network while being connected with VPN
Hello
We have a PIX 515E with a remote access vpn.
Our internal network has an address network 192.168.1.0/24, and addresses we assign to vpn clients are 192.168.1.49 - 192.168.1.62, or 192.168.1.48/28.
When I connect to the vpn, I cannot ping none of my hosts internal. The error I get is "no group of translation not found for icmp src:...» »
It is quite clear that I would need a NAT rule, but why? Addresses are in the same network...
Could someone enlighten me on how I should proceed to nat traffic between vpn clients and the internal network?
Thank you.
