My need : I would like to make the local network printer work when I am using my VPN with cisco AnyConnect Sure Mobility Client VPN.
When I not conected to the VPN, I am able to ping the printer and use it, but when the VPn is on, routing tables are changed and I am not able to ping and use the printer anymore.
Our system :
All PCs and the printer are connected by ethernet to the same hub, we
are working with static IPs.
Printer IP : 192.168.1.49
Default gateway : 192.168.1.1
Cisco client configuration file (I can't give you the whole file because there is confidential information in it) :

What I tried :
enabling the "Enable Local LAN acces" in preferences tab. -> doesn't
work
set the LocalLanAccess paramter in configuration xml file to true but when i conected to the VPN, this parameter is automatically reset to false.
route add 192.168.1.49 mask 255.255.255.255 192.168.1.1 -> doesn't
work
My network knowledge is limited, I hope to find a way to solve the problem.
Seems like the VPN Client connection is configured as "Full Tunnel". This means everything from the users computer is tunneled to the VPN connection while its active.
This might cause problems with using local resources at the users LAN at that moment and also if not "properly" configured, might not allow using Internet at the same time.
Here are two solutions that could help:
1) Reconfigure the VPN Client connection so that it uses Split Tunneling. While Split Tunneling is in use, the VPN Client users computer will only forward traffic destined to specific networks to the VPN connection and all other traffic either stays in the local LAN or heads out the local Internet connection like usual.
2) Configure the VPN Client connection so that it also permits Internet connectivity through the VPN Client connection. In this case the users Internet traffic would first travel to the remote site through the VPN and then possibly "hairpin" to Internet through the customers VPN devices outside interface
While connected with the VPN client, you can confirm how the VPN has been configured by looking at the "Statistics" section of the VPN software. It should contain a section for routes. Check what the routes section says. (might be different depending if you are using the Cisco VPN Client or Cisco AnyConnect VPN Client)
If it has
0.0.0.0 0.0.0.0 = It means that all traffic is forwarded to the VPN while its active
Hope it could help.
You need to enable local LAN access. Editing configuration XML is not the correct way to do that.
In AnyConnect parlance, we call the configuration XML as a client profile.
Every time you connect with the VPN headend; AnyConnects checks for updated version of AnyConnect software or client profile. If there is a different version of client profile available on the server (ASA); AnyConnect will replace your local version with the one that is available on the server.
Which explains why this is happening.
set the LocalLanAccess parameter in configuration XML file to true but >when i connected to the VPN, this parameter is automatically reset to >false.
You need to contact the network admin and request for local LAN access.
If you are the network admin, please update the profile that is present on the ASA. This can be easily done through ASDM.

Your probably "tunnelling all" set it to only tunnel to said networks - meaning you will be able to surf locally and it not go through the tunnel.
<LocalLanAccess UserControllable="true">false</LocalLanAccess>
That line in your XML file doesn't allow the user to control local LAN access.

I don't think that we can share the link that we get from the live server extension to someone else for viewing our web page.
kindly advise me. I am new to front-end development.
By default LiveServer will listen for network connections on 127.0.0.1 and is available only to clients running on the same computer.
You can change that in the settings (under Live Server > Settings:Host) to specify any IP address allocated to the computer you are working on. You can also use 0.0.0.0 for every IP address allocated to that computer.
Anyone who can reach the IP address you select (which is typically anyone on the same LAN as you) can then visit http://192.0.0.10:5500/ to see the site. (Replace the IP address in that example with the one assigned to your computer that you selected above).
For someone to access the server from a different network, you will need to have an IP address on the public Internet. Typically you would get this by following the above instructions and then configuring your router to forward port 5500 from its Internet facing IP address to the IP address of your computer on the LAN.
You can also look at tunnelling a connection with by creating an SSH tunnel manually or using a service like ngrok which connects a URL on the public Internet to your local server (note that this removes the requirement to change the Live Server configuration away from 127.0.0.1).
I am trying to locally run a PHP based project, connecting to an Amazon RDS instance. I am receiving the following error in the browser:
![SQLSTATE[HY000] [2002]]1
I have run a series of networking tests where I pinged the following and received successful test results. I pinged:
iiNet's web address
One of iiNet's DNS servers
The loopback address of my computer
I pinged Google
I then tried the mysql utility to remotely connect and received the
ERROR 2003 (HY000): Can't connect to MySQL server
Last factor I think you should know regarding my own networking situation, I am connecting to the internet via:
modem->Zyxel VPN->Wireless Router->My laptop
What in the Sam Hill is going on?
Thanks,
CM
For this to work, the following must be true:
the RDS instance must resolve to a public IP address (I'd check this for you but since you chose to use a screenshot instead of text, I can't copy paste it, so I'll leave it to you)
the Security Group(s) associated with the RDS instance must allow traffic from your public IP ( the one you'll get from http://wtfismyip.com/text ). This won't bet true by default. I highly recommend you open to your IP, not just everyone, as Mysql is trivial to DOS attack if its port is public.
The network ACL of the VPC hosting the RDS instance must allow the traffic also. This will be allowed by default, so unless you changed the ACLs in your VPC, you can ignore this.
If all those are true, you should be able to connect!
I have created a VM instances on Google cloud and i want to access it from WAN. I try type address in address bar but it say server down. I can remote desktop to my window instance but cannot access it in browser.
What is the problems? How to solve it?
You can access linux instances with SSH and windows instances using remote desktop. More details can be found in the google cloud documentation here.
Update:
If you want to enable http access to your website then you need to
1) Make sure you are trying to connect to correct external ip address. Your server will either have a static or Ephemeral ip address. Ephemeral ip address changes every time you reboot your server. Static ip doesn't change, but it is not free. More details here.
2) Make sure you enabled http access in your firewall settings. (Maybe you forgot to check this option when you are creating your virtual machine?) To set the firewall settings go to Networking -> vpc network -> firewall rules
My local machine is not connected to internet. However, I have a server on local network which I can connect via SSH. This server is directly connected to internet. I do not have the admin privileges on the server, so I cannot install a browser on it. However, I can download web pages on it using wget. I was wondering if there exists a way so that I can browse internet using a regular browser installed on my local machine.
If you have SSH access to the server you can try using it as a proxy.
ssh -D 8765 user#host
Then you need to set a SOCKS5 proxy on your browser pointing to 127.0.0.1:8765 and you'll be ready to browse the Internet as long as the SSH connection is alive.
The port 8765 is used just for example. You can use any port between 1025 and 65535.
If it's allowing you to get webpages with wget, you might want to see if the server is set up to be a proxy server.
Is there a performance difference between TCP connections to:
localhost / 127.0.0.1
a domain which resolves to the local machine
Or more specifically, do the latter connections go through the loopback device, or over the actual network?
The reason I'm asking is I'm thinking about changing database settings in many PHP apps so they use a full domain instead of localhost. That way we could more easily move the database to a different server, if the need arises.
This is implementation and operating system dependent. On Windows, anything connecting to a local IP address, even if it is an outside-facing IP, will go over loopback. This is a documented problem for applications such as packet sniffers, because you can't sniff the loopback. (Windows doesn't treat loopback as a "device" -- it is handled at the network level.) However, in this case it would work in your favor.
Linux, in contrast, will follow whatever you have in your routing table, so packets that are destined to your local machine will go to your local machine over the network if the routing table isn't properly configured. However, in 99% of the cases the routing will be configured properly. Your packets won't go over the loopback device, but the TCP/IP stack will know that you are contacting a local IP and it will virtually go out and back in the proper ethernet device.
In a properly configured environment, the only bottleneck for using a domain name would be DNS resolution time. Contacting an outside DNS can add additional latency into your configuration. However, if you add in the domain name into your /etc/hosts file (C:\Windows\System32\drivers\etc\hosts on Windows), your system will skip the DNS resolution phase and obtain an IP directly, making this time cost moot.
That depends on how the names are resolved. The procedure is typically /etc/hosts first and then DNS if that fails. If localhost is in your /etc/hosts, putting whatever.wherever in the file as well will make it resolve with the same speed.
