Virtual Private Network Frequently Asked Questions

1. Why do I get disconnected after 4 hours of use?

(a) You will get disconnected because of the limited number of ports and the fact that 90% of all users do not need to be connected more than 4 hours, all units have been set to a 4-hour time limit.

(b) If you require more time, you should disconnect gracefully before the time limit and reconnect so that you do not lose your work.

2. Why not use an 800 number all the time?

(a) Using an 800 number costs the corporation 5 cents a minute versus calling a local number when available that costs 5 to 7 cents one time charge to initiate the call with no per minute charges.

3. Do I have to be connected when Email comes in or to prepare Email?

(a) No, Email is stored in your server until you need to access it.

(b) The proper way to handle Email when working remotely is to make a connection periodically during the day pulling your mail down and then disconnecting.

(c) You can prepare your Email in the offline mode.

(d) When you make your next connection to process incoming mail all prepared mail can be sent at this time.

4. What about reconnection issues?

(a) If you are running Windows 95, NT, 2000 or XP making re-connections should be as simple as clicking on the icon to reconnect.

5. How do I speed up my dial-in connection?

(a) Only install the necessary protocols.

(b) Usually IP is the only one needed unless you are accessing Novell Servers.

(c) Never install NetBEUI.

(d) A good practice, if only accessing Novell Servers occasionally, is to create two configurations, one with IP access only and one with both IP and IPX. Use the second configuration only when required.

6. Why can’t I see all of the NT units in the Network Neighborhood?

(a) When you dial into the Network Access Gateway you are normally on a segment without a master browser, which is how units are displayed in the Network Neighborhood.

(b) This does not mean that you cannot access the unit however.

(c) If the unit you are trying to access is a member of the corporate WINS structure and you have configured your remote unit per the configuration instructions, WINS will automatically resolve the units IP address when you Map a drive in Explorer vpn voor netflix.

(d) The key to this is to know the computer name and share name that you require before starting the process.

7. Why does my Dial-Up Networking fail to work after loading AOL?

(a) AOL sometimes replaces the TCP/IP Winsock driver, causing your PC perform erratically or not at all.

Fix:

1. Delete all references to TCP/IP from the network neighborhood properties.

2. Reboot the system.

3. Add the Microsoft TCP/IP protocol back in.

This will automatically add TCP/IP to all adapters and you should be functional again.

8. Can I use Network Address Translation (NAT) to attach my home computers via VPN?

(a) In general NAT is not supported by the IPSEC VPN client.

(b) Routers such as the Linksys BEFSR11 and BEFSR41 do support VPN with a software workaround.

(c) NAT implementations may be used if One-to-One NAT is used.

9. Why can’t I get higher speed on my 56K v.90 modem into some NAG sites?

(a) A 56k v.90 modem is asymmetric by design, so download speed can be as much as 56k but upload speed will be only up to 33.6bps.

(b) For 56k to work, there must be only one analogue to digital (A/D) conversion in your local phone loop.

(c) Thus when modems at both ends are analogue, 56k speeds will never be achieved as most PSTN exchanges run digital routing.

(d) Some NAG sites use analogue phone lines with Cisco and standard 56k modems, while most PCs dialing up use a similar modem.

(e) Between both the modems, it limits the download speed to about 33.6kbps maximum.

(f) At the same time, many users might experience lower connection speeds due to other reasons, such as more poor line quality.

(g) These factors will also contribute to the quality and speed of the line.
