Hi there,<br />
I am setting up an Asterisk VoIP server and having difficulty with Hamachi VPN. &nbsp;Hamachi runs natively on the Linux side, and I also have a Windows client. &nbsp;Approximately 30 seconds after Hamachi has made a connection, on my Windows PC, I see the light showing a connection to a particular machine go from solid to flashing. &nbsp;This means it is having trouble with tunneling. &nbsp;I am not sure how to fix this; I have tried uninstalling &amp;&nbsp;reinstalling Hamachi on the Linux box to no avail. I am thinking that it has something to do with a firewall setting but so far as I know, I should not have to open up any ports on it. (I use a Buffalo router running Tomato firmware.)<br />
<br />
Does anyone have any ideas how to fix this?

Hamachi on Linux

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.

Networking Protocols

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
