(1) Your Virtual Private Network Connection
Experiencing difficulty interfacing with the Internet at home attempt these means before calling for help.
1. Do you have an IP address? Attempt ipconfig/all. In the event that you don’t have an IP address reboot your PC. On the off chance that that doesn’t work power cycle your Cable/DSL modem and switches and reboot your PC again after the system gadgets are up and stable. Make certain the greater part of your system links are connected to tight. hidemyass
2. After your PC reboots watch that your system connector is dynamic and parcels are streaming. Play out the ipconfig/all check once more.
3. Check your availability by pinging a few Internet destinations. In the event that that does not work, ping the loopback address 127.0.0.1. On the off chance that that fizzles, your connector may not work or it is not appropriately arranged.
To check your IP address. From summon brief enter ipconfig/all (as appeared in the photo) you ought to see an IP Address and a few DNS Server addresses. The area name framework (DNS) is the way that Internet space names are found and deciphered into IP addresses and is required for skimming the Internet.
Ping 127.0.0.1 – loopback Test (as appeared in the photo). The loopback test is utilized to check if the IP stack is reacting. On the off chance that it times out or you get a blunder the issue may happen if any one or a greater amount of the accompanying conditions is valid:
*The TCP drivers are tainted
*The system connector is not working
*Another administration is meddling with IP
Check your system connector, tap the Start menu, Settings, Control Panel, and select Network Connections. Double tap on the Local Area Connection or the Wireless Adapter whichever one you are utilizing. Make certain its Connected. On the off chance that you have different system cards debilitate the one you are not utilizing.
There ought to be Packets shown in both the Sent and Received counters. On the off chance that the Received counter is 0 watch that the connector has an IP address. Select Properties.
Click the check boxes for Show symbol and Notify me beneath. A twin PC symbol will show up on the lower right divide of the taskbar in the plate zone and will streak while sending and accepting parcels. You can put your mouse over the symbol to get the status and snap on it to get more points of interest.
Tracert shows the association way to the objective area and the quantity of jumps. Every jump is the excursion starting with one switch then onto the next. Tracert is a convenient device both for understanding where issues are in the system and for deciding dormancy between bounces.
Ping is utilized to figure out if a host exists and is dynamic on the system and can decide the round trek time to the gadget. You can enter a host name or an IP address in the event that you know it. In the event that the solicitation times out then the host is not reachable in light of the fact that it’s disconnected or there is an issue with the association. Attempt a few destinations, if none work then ping the loopback address 127.0.0.1 Also, if your DNS is not working or appropriately designed you can just ping the host with an IP location and you won’t have the capacity to skim the Internet.
On the off chance that you are having irregular issues, play out a ping – t for 5 to 6 minutes then hit CTRL C to see the consequences of the test to figure out whether you are dropping system parcels (lost bundles). In the event that you are, this as a rule demonstrates an ISP issue or Cable/DSL modem issue. See VPN ISP Troubleshooting Guide
(2) VPN Troubleshooting Error Messages
Q1 Error Message: Remote Host not reacting: or Unable to Resolve the IP location of the Remote Server
Cause: This demonstrates the Contivity VPN Switch never reacted to the association endeavor. The issue could either be with the Contivity switch itself, (switch might be down) or your machine might have an issue determining the IP address.
Activity: Try pinging your goal name (Example: VPN.something.com). In the event that you got a message that says “Demand Timed Out” from the ping charge, call your ISP to ensure that their DNS is working accurately.
Q2 Error Message: Maximum number of sessions came to
Cause: This demonstrates the most extreme number of clients for the record you are utilizing are as of now signed on.
Activity: If you are the main client with VPN to your record, it is conceivable to get this blunder in the event that you restarted an association quickly subsequent to losing the dial-up association with your ISP. This is on the grounds that the Contivity VPN Switch takes up to one hour to verify that your association has been dropped and log you off from your record.
Q3 Error Message: Login fizzled, Please counsel the switch log for additional data
Cause: The User Name or the Password is erroneous for the client name entered.
Activity: Verify that the User Name you entered is right and retype the Password before attempting the association once more.
Q4 Error Message: The physical association has been lost
Make: Your association your ISP was detached.
Activity: Re-build up your association with your ISP before you re-set up the Contivity association with the remote system.
Q5 Error Message: The protected Contivity association has been lost
This message can come about because of various diverse reasons, and there are a few prescribed moves you can make to attempt and re-associate.
On the off chance that you get this blunder before the customer associates then something is obstructing an essential port, (for example, ESP port 50). This can come about if your firewall is not designed appropriately and is limiting the essential port(s).
On the off chance that you get this blunder amid an association and you all of a sudden get the mistake it might mean one of the accompanying:
1. Something shut the association;
2. The VPN Contivity switch where you were attempting to interface with thought your customer was down or planned out;
3. Your nearby ISP accomplished something that interfered with your system association sufficiently long for the VPN Contivity switch to recognize your customer was not reacting;
4. The VPN Contivity switch that you are associated with has either logged your association off or the Switch is no more reacting, or a gadget that does not bolster IPSEC NAT Traversal is bringing about the association disappointment.
1. Attempt re-setting up the Contivity association by tapping the Connect catch. In the event that this works, the association was most likely lost because of the Idle Timeout arranged on the Contivity VPN Switch. In the event that no information is exchanged through the Contivity association for a drawn out stretch of time, 15 minutes or more, the Contivity VPN Switch naturally disengages the association;
2. In the event that you were not able effectively re-set up the Contivity Connection, the dial-up association might keep information from going between the Contivity VPN Client and the Contivity VPN Switch. Hang up the dial-up association and reconnect before you attempt to re-build up an association with the Contivity VPN Switch;
3. In the event that you are still not able to associate with the Contivity VPN Switch, open a Command Prompt and have a go at pinging the Contivity VPN Switch utilizing the host name or address that you determined in the Destination field.
(an) If you get a “Goal Unreachable mistake” there is a steering issue at the ISP.
(b) If you get a “Solicitation Timed Out” mistake message, the Contivity VPN Switch is most likely not accessible, and you ought to contact your Network Administrator.
4. On the off chance that you continue getting this message and can’t associate, then it might show that the Contivity VPN Switch can’t speak with the customer since it is behind some sort of NAT (Network Address Translation) gadget. NAT (Network Address Translation) Traversal permits various gadgets on a private system to get to the Internet all the while without each requiring its own outside IP address. Most inns and air terminals that give Internet network use NAT to associate with the Internet.
Q6 Error Message: Cannot Alter Routing Table
Cause: Message implies the you the client, an application on your machine, or your ISP endeavored to change the directing table by means of an ICMP divert endeavor and it was not fruitful. The customer identifies the endeavor to roll out the improvement, decides it’s a security rupture and close down the customer’s association. At whatever time you make a VPN association, you can’t change the directing table, on the grounds that the VPN Client sees this as a security danger and you will get detached.
A few applications require an ICMP redirection keeping in mind the end goal to work, for example, a diversion or other outsider programming.
Activity: If you get this mistake and cant interface due to an ICMP divert endeavor, close down some other applications you are utilizing which might bring about the ICMP divert endeavor. In the event that it is the ISP that is doing it, you should hinder the ICMP divert demand. You can recognize that ICMP divert has happened, by seeing a message saying there has been an IP address directing table change.
Q7 Error Message: Receiving Banner Text Information
Cause: Message implies you are encountering a Banner Sock issue, and will see a window showing the “Accepting Banner Text” message and afterward gets detached.
1. Impair the firewall totally to test. This is a port 500 issue and regularly implies that the you have an individual Firewall that is blocking port 500 or you have a switch that does not bolster IPSEC go through, and the you are interfacing with a VPN switch that does not have NAT Traversal empowered.
2. In the case of utilizing remote, incidentally expel Wireless from the photo and spotlight on the Ethernet card. Check the Ethernet card speed and duplex parameters and afterward ensure that the center, switch, or switch that is on the flip side has the same parameters. If not, the VPN association will drop as the connection goes here and there, or because of an extensive number of mistakes on the port from a duplex as well as rate jumble.
3. Firewall that obstructs the association, with the end goal that framework will crash. (This will infrequently happen) NSD
