Some students who have Cable Modem service or use a network have indicated problems accessing the Desire2Learn Log In page or class sites. In most cases, the problem was traced to the default settings as High Security. Because Firewalls monitor risky connections, you may need to reset the overall settings to Medium-High or Medium. Make sure that you are not blocking all ports, and if problems persist, power down the firewall and restart your system.

Yes. If you have more than one computer in a home or small-office network, you should protect every computer in the network. Turning on Windows Firewall or another firewall on every connection will help prevent the spread of a virus from one computer to another in your network if one of your computers becomes infected. However, if you open an infected e-mail attachment, the firewall won't block it and it can infect your computer. You should install an antivirus program as well.

If your computer system connects to the Internet through a firewall or proxy server, certain TCP ports may need to be opened in the firewall or proxy server in order for you to connect. To open these ports, consult the help files for your firewall software or contact your network administrator or IT technician for assistance.

All computers in your home network should be protected by a firewall. A firewall helps to prevent the spread of viruses or worms across your network if they infect one computer. A computer on the network could also become infected through a separate Internet connection, such as a laptop that is used on your home network and on public networks. Or, a virus could be introduced to a computer on your network through software installed from a CD or floppy disk.

A firewall will help protect a computer on a wireless network, but will not restrict access to the network itself. You should configure your wireless network to use a network key using either Wi-Fi Protected Access (WPA) or wired equivalent privacy (WEP). For more information, see How to keep others from hijacking your home wireless network or consult the manual for your wireless networking devices.

Yes, but a proxy server or firewall that has not been reconfigured can limit some HotOffice functionality, such as web-based installation, document publishing, and email attachments. Since a proxy server or firewall is designed to block outside access to a network, including access to your HotOffice, your company's system administrator must grant HotOffice access through its firewall by opening the passageway.

Yes, as long as the firewall allows normal http and SSL (secure sockets layer) connections. RelationshipSecure uses regular "http" and "https" requests to set up mailings and transmit faxes via the Internet. The 407 error is generally associated with using a proxy server. Check with your network administrator about the settings of your proxy server. Your administrator may need to change the settings for www.relationshipsecure.com so .exe files can be downloaded.

Yes. Windows XP users who want different features in a firewall may use a hardware firewall or a software firewall from another company. For special offers on antivirus and firewall packages, visit our Security software: Downloads and trials page. No. Running multiple software firewalls is unnecessary for typical home computers, home networking, and small-business networking scenarios.

Yes. You should turn on the Windows XP Internet Connection Firewall for all computers in your home network. This helps prevent the spread of viruses or worms across your network if a computer is infected. A computer on the network could become infected through a separate Internet connection, such as one on a laptop that is used on your home network and on public networks. Or a virus could be introduced to a computer on your network by way of e-mail or software installed from a CD or floppy disk.

To view the videos and multimedia available on Encyclop?dia Britannica Online School Edition, in addition to having the correct plug-ins, schools must also have the proper network settings. Network settings may need to be modified by the schools technical support staff.

Yes. If you have multiple network connections on any of your computers, you should turn on the firewall for each connection. If you're running Windows XP SP2, Windows Firewall is turned on automatically and it should not interfere with common tasks like file and print sharing. If you're not running Windows XP Service Pack 2, Internet Connection Firewall can interfere with file and print sharing and prevent your computer from finding other network devices.

Yes; you can use TCP forwarding for that, by using its secure TCP forwarding features. You can also tunnel through another open port through the firewall (I'm sure all those system admins love me now :-) by running a daemon on the remote side on a port that's allowed through a firewall, like SSL (port 443).

Socks 4 and 5 support should work in 1.2.16 or later. Socks support in version 2.0.11 and later should work.

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The actual means by which this is accomplished varies widely, but in principle, the firewall can be thought of as a pair of mechanisms: one which exists to block traffic, and the other which exists to permit traffic. Some firewalls place a greater emphasis on blocking traffic, while others emphasize permitting traffic.

One of the most frustrating tasks in setting up a network is getting computers with different firewall settings to communicate with each other. Network Magic makes it easy by automatically detecting the different firewalls, like Symantec/Norton, McAfee and Zone Alarm, and walking you through the key settings you need to adjust to allow your computers to communicate with each other.

Unfortunately, that's far too complicated a question to answer here. In general, turn compression off, and turn uucp 'spoofing' on. This can all be done on the fly by sending register settings as part of your send-expect sequence when you call out, or you can do so as part of your modem initialization string in static. Some Telebit modems don't save the register settings. You might have to set the registers in both the init string and in the calling sequence.

A NAT is often used between private networks (like those used at home or at work) and the Internet to map a private IP address to a public IP address. Routers and software gateways (such as Internet Connection Sharing in Windows) usually also function as NATs. Firewalls, on the other hand, filter access to protected networks. Netphone2phone works with most NATs and firewalls without any additional setup.

Because the Actiontec Wireless-Ready DSL Gateway uses NAT firewall security, it is not necessary to use any other program for security. The use of third party firewall or Internet security software is not recommended, as certain programs will create problems on a private network (BlackIce Defender, Norton Internet Security, and ZoneAlarm, for example).

Think of eBLVD as you think of accessing secure 128-bit SSL web pages. A sophisticated hacker could intercept your web session but would only see encrypted data. The hacker would need to decode each individual stream of data and reassemble it to be able to view the data. This is virtually impossible.

A NAT is often used between private networks (like those used at home or at work) and the Internet to map a private IP address to a public IP address. Routers and software gateways (such as Internet Connection Sharing in Windows) usually also function as NATs. Firewalls, on the other hand, filter access to protected networks. PalCalls works with most NATs and firewalls without any additional setup.

A proxy server or firewall that has not been reconfigured can limit some TrainingDepartment.com™ functionality, such as Web-based installation, course authoring, student record-keeping and some learner’s response tools and testing. Since a proxy server or firewall is designed to block outside access to a network, including access to your TrainingDepartment.com™, your company's system administrator must grant TrainingDepartment.

Answer: No. CentralPoint is designed for quick, simple installation and requires no changes to your firewall.

The HIGH setting is pre-set to allow only Mail, News, Web, FTP and IPsec traffic through the Firewall. Setting up port forwarding rules cannot modify this setting. The MEDIUM setting offers the same protection as HIGH, except that it can be modified by setting up Port Forwarding rules. The LOW setting offers a lower level of security, but is ideal when trying to use a service where you are unsure which ports to open on the firewall.

All firewalls work on a 'gateway' principle. The client connects to the firewall and sends a request to open a connection to any remote FTP server. Therefore, this property is not the same as the name of the FTP server specified when running the OsaSync connection wizard. Please note the properties that need to be set when using firewalls: Firewall Hostname as the remote firewall server, Firewall Port as the server's port, and the Type of firewall.

Enter the firewall settings if the computer goes through a firewall to get to the SMTP server. These settings do not refer to a server firewall, but to a local firewall.

AODV encapsulates its control packets using UDP. It addresses UDP packets to port 654. Additionally, a prober application that detects unidirectional links communicates over port 30010 using UDP. The AODV package also sends outgoing UDP packets addressed to port 30005. Therefore, you need to configure your computer to allow incoming and outgoing UDP packets addressed to ports 654 and 30010 and outgoing packets on port 30005.
