Explanation / Answer

A. Information needed prior to troubleshoot the VPN:

1. Basic understanding of the VPN ,Network security , Ethernet connection , LAN/WAN etc.

2. VPN , Adminstrative Guide Version NGX R65.

3. Encryption Methods and concepts

4. Netweork Architecture of the location/ field where the VPN is setup or established.

5.Logs and records of the system before and after failure.

B..One of the first thing you should do for troubleshooting is to collect the logs from the system to get the idea of the tyope fo the issue that caused the problem.

C.

1.Restart the VPN Software

Yes, it’s might be acliche, but closing down the software can get things running smoothly again. If your VPN has its own program, close it down (all the way, make sure it’s not just minimised on your computer), and restart it.

If the VPN is a browser plug-in, close your browser down and restart it.

2.Make Sure the VPN is Up To Date

VPN software is regularly updated. Some of these take the form of quality of life tweaks to make the program easier to use, but others will be essential for the day to day functionality of the VPN, so it’s important to make sure that you don’t ignore update requests.

3.Using firewall ports. Before placing a VPN server behind a firewall, verify that the firewall software accepts PPTP packets. Sometimes firewall software packages (including some versions of Check Point Software Technologies' FireWall-1) don't accept PPTP connections when it can configure the firewall with Network Address Translation (NAT—for information about NAT, see Zubair Ahmad, "Windows 2000's Network Address Translation," February 2000). In this situation, the client's attempt to connect to the RAS server produces the error message Event ID 721 PPP remote peer not responding. When you place a VPN server behind your firewall, be sure to enable IP protocol 47 (Generic Routing Encapsulation—GRE) and TCP port 1723. The connection uses port 1723 for general housekeeping, such as PPTP tunnel creation, maintenance, and termination. Port 47 passes tunneled data between the client and the server (including the GRE protocol), and wen also need TCP port 1723 [established] if we are supporting RAS server-to-server VPN connections.

4.Use OpenVPN Client Instead

As the name suggests its an open source protocol. It’s secure, and has been around for over 15 years.

It’s very popular in the VPN community, thanks to its native compatible with a large range of platforms, including iOS and Android, as well as MacOS, Windows and Linux. It works with most of the big name VPNs, so could well be the answer to your woes.

5.Make Sure Your VPN is Compatible with the Site or Service

6.Testing DNS Resolution: Most end users will access resources using hostnames, so also test DNS resolution from a command prompt or terminal.

7.Check for Network Access Protection issues

Microsoft created the Network Access Protection feature as a way for administrators to protect network resources against remote users whose computers are not configured in a secure manner. Although Network Access Protection (NAP) works well, it has been known to cause problems for end users.

8. Try accessing resources by IP address rather than server name

Try connecting to network resources by their IP address instead of by their name. If it can be accessed previously inaccessible resources by using IP addresses, we can bet that a DNS problem is to blame. If that happens, check to see which DNS server VPN clients are configured to use.

D.Things not to do:

1. Stop using the outdated VPN softwares.

2. Don't install freeware softwares.

D. Things to Do : Check is whether affected users are connecting from computers that are behind a NAT firewall. Normally, NAT firewalls aren't a problem.

E.Initial things that could be done are:

1. Configure the on-premise VPN device to be responder-only as the VPNaaS will always make sure tunnel is up (barring networking issues between OCI-C and the on-premise VPN).

2. If some subnets work and others do not, make sure both sides agree on the subnets participating in the vpn. If there are more subnets defined on the on-premise VPN device than the VPNaaS, the VPNaaS will not report a problem since it does not know about the other subnets.

Some of the tools are :

1. IPSec Lan-to-Lan Configuration Checker

2.MTU PingTest
