Desktop firewalls work by monitoring, passing, or blocking incoming and outgoing network packets. Rules govern what to look for and what to block or pass. Typical firewalls block based on source and destination address, port, packet type, etc.For most users, the default settings (rules) of a host-based firewall are enough. Host-based firewalls are available for Macintoshes, PCs and various flavors of UNIX.

Yes. You must ensure however, that port 3306 is available in order to permit connection to your remote mySQL server. Network Address Translation boxes are not a problem. Non-translating proxies might be however - contact your systems administrator if you are operating under a proxy to ensure that packets will be properly routed.

Yes, the InfoGate 3020 can work behind a firewall or NAT, by opening the following ports: TCP/IP: 8481 UDP: 6024, 6026, 6028 & 6030 UDP: 1588 for InnoSphere

Yes. Remote Backup can be configured to operate through nearly all firewalls. In order for your computer to connect to Remote Backup, it must be able to send outbound TCP/IP packets to port 16384.

Try changing the distance between the remote control the HP-100 or the HP-100 and the device you want to control. Also try removing the plastic IR cover when recording and/or sending. IR is programmed to use 40KHz as the carrier frequency. There are some devices that use another frequency and therefore can not be controlled by IR.

For most routers, yes. The service is designed to work behind a NAT router and you should be able to just plug in and go, assuming your router is handling DHCP services. In addition, there is an excellent network connection troubleshooter built into the XBL front-end. You can configure your Xbox with a static IP if required, you can manually set various network settings, and you can even have the Xbox spoof a certain MAC address if required by your ISP.

This depends upon how your firewall / NAT server is configured. Please ask your network administrator if your firewall (or NAT server) is configured to allow PING and TRACERT to work (which use ICMP ECHO, ECHO REPLY, and TTL EXPIRED packets). You can test this yourself by running these programs on your computer (For example, try "tracert www.visualware.com"). If these programs work, VisualRoute should work just fine on your computer.

It should work with any type of firewall including Symmetric NAT. Symmetric NAT is performed only by advanced enterprise routers, in that case NATPass™ will recognize this scenario and will make the call succeed by signaling and doing RTP bridging. It is all transparent for the user and there is no need to reconfigure anything.

A desktop firewall is software that runs directly on a computer (i.e. the host) and protects that host against attack from the network by controlling incoming and/or outgoing network traffic. Sometimes they are referred to as host-based firewalls. There are other kinds of firewalls that sit on the network between one or more computers and the rest of the network whose purpose is different than that of host-based firewalls.

You can find classification of NAT in RFC 3489 – STUN http://www.faqs.org/rfcs/rfc3489.html. It should not mater what type of firewall you have.

Yes. WuWu is completely Firewall/NAT compatible! For additional information on this topic, please read the WuWu Firewall / NAT how-to.

The quick summary: You need to forward your ports if you have NAT in order to get the fastest speeds. This is probably the most common thing that people fail to do when using BitTorrent. Read on for more details of what all this entails, and if it's something that you need to do. Prior to version 3.2, BitTorrent by default uses ports in the range of 6881-6889. As of 3.2 and later, the range has been extended to 6881-6999. (These are all TCP ports, BitTorrent does not use UDP.

Depending on your configuration, when you first start up the program you may get a notification asking you to permit Desktop Action to communicate with our dedicated submission server. If you simply set up a rule to permit this for the regular internet HTTP port 80 you will be just fine. You should set up a standing rule because the program automatically updates its own menu selections periodically.

If due to the security policy accepted in your corporate network or by your host provider you cannot connect to your MySQL server directly through TCP/IP (for example a firewall prevents this), you can use SSH or HTTP tunneling feature of SQL Manager to fulfill your task.

Remote device refer to device far away. In other words, if you have a computer and PDA connected together via Bluetooth link; PDA will be referred as remote device and computer will be referred to local device.

Yes, but you will get better performance if other peers can connect to you. By default, BitTorrent listens on port 6881, trying incrementially higher ports if it's unable to bind. It gives up after 6889 (the port range is configurable.) It's up to you to figure out how to poke a hole in your firewall/NAT.

Incoming traffic is usually accomplished by simple port-forwarding, with certain types (fragmented, for example) of traffic filtered out. Although ports can be forwarded to other internal IP addresses, this isn't generally referred to as NAT, which includes port-remapping as well as forwarding.

If due to the security policy accepted in your corporate network or by your host provider you cannot connect to your InterBase/Firebird server directly through TCP/IP (for example a firewall prevents this), you can use SSH tunneling feature of SQL Manager to fulfill your task.
