Problem with installing  3000 CISCO VPN service

This is a very common problem when you are trying to install the VPN service. But luckily, this is a very easy fix. The only thing that you need to do is to disable ICS on your machine before you install VPN client on your PC. We definitely recommend that you replace ICS with a good home router that has a good firewall. But this problem can be also avoided if VPN connects through another machine that uses ICS. Here are the steps to disable the ICS. First, you need to go to the Start button.

Using the shared keys

This usually occurs when you have more than one PC-s at home and only one VPN service. At that point usually, only one PC can use VPN service. To fix this problem you need to go to the Configuration/System/Tunneling Protocols/IPSec LAN-to-LAN option and then select your IPsec configuration. Then you need to enter your pre-shared key. Then, on a Cisco PIX firewall used in conjunction with the concentrator, use the command is amp key password address xx.xx.xx.xx netmask where the password is your preshared key. The key used in your concentrator and on your PIX should match exactly. And this should fix your shared keys problem.

Problems with accessing other resources on your PC while using the VPN connection

This problem usually results of split-tunneling being disabled on your PC. Split-tunneling can pose some security risks. The reason is because, on the one hand, you have VPN service, but on the other part of the split tunneling, you are using your PC without any real protection. The best way to fix this problem is to install the high-quality antivirus program that will protect you while you are accessing other resources on your PC. This is a simple fix and very useful. VPN protect your privacy online. While antivirus programs protect your PC from potential viruses that can be hidden in the programs that you have downloaded or that you have already installed on your PC.

It can happen that you have done pretty much everything that you can to fix your VPN problem. And nothing works, literally, nothing had work. And then you need to ask yourself. Maybe the problem isn`t on your PC, on servers in your business. The problem could be made by the VPN company itself. We all know that every time when companies are updating their software, that there is a high chance that updated version of the software will have some bugs that will not allow proper function of the VPN service. And the way to fix this problem is to contact the VPN provider. Tell them about the problem that has occurred and that you have done literally everything to fix it and that nothing had worked. Then you inform them that there is definitely something wrong with their software. And we can`t blame them, there are so many lines of code every time when the update of the software is done. The only thing that you need to hope is that they are great with the customers and that they will resolve the problem as fast that they can.
