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.

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.

Outgoing SSTP connection can pass through any kind of NAT and firewalls - as long as TCP port 443 is allowed (which is normally the case). If the VPN client is behind a web proxy, then outgoing SSTP connection can go through in normal web proxy. SSTP does not support "authenticated" web proxies (i.e. proxies which require some form of authentication during HTTP CONNECT request).

Currently, Miredo cannot serve as a Teredo client behind a symmetric NAT. However, in preparation for this to eventually become possible, Miredo can accept other clients behind a symmetric NAT (as of version 0.9.8). It's a matter of time before Miredo supports symmetric NATs to a larger extent (however in any case, support for symmetric NATs will never be equal to support for other NATs due to limitations of symmetric NATs).

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

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.

In this case, the packets used for IP telephony are intercepted by your router, and you cannot make any phone calls. To solve this problem, try to activate UPnP on both your router and AGEphone (related materials).

If the packet is to go out the WAN interface, the router applies NAT (Network Address Translation) by changing the packet header's source address from the originating device's private LAN IP, to its own public IP address. Thus when it arrives at its destination, it will appear to have originated from your routers public address, and any reply will be sent there.

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.

Our first recommendation would be a hardware based NAT router such as the Linksys BEFSR41. With it, you can share your internet connection between all of your computers. Or, if you do not with to install a router, install something like BlackICE or Zone Alarm. As always, we request that you install a good antivirus package such as AVG on every computer.

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

No. Our products run on application layer, and application layer need not be aware of Diffserv or MPLS. Media marking, however, can be done as most Operating Systems seem to allow us to set the DSCP byte.

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.

Absolutely. Our specialists will provide you with the required proprietary firewall port information. In most situations, firewall changes are NOT required.

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.
