I'm in need of help, in getting the right configuration.
I have a Linksys ATA Device, which I need to have connected constantly to a South African VPN server, otherwise my VOIP link won't function.
A temporary way, till I get a dedicated Device, is I want to install DD-WRT (Preferably), or XP on a virtual machine, with either VMWare, or Virtualbox, and then install an image DD-WRT's x86 port, which should keep me going, till I'm able to find an old PC (Pentium 1 preferably), that I'm happy with.
I have the feeling all DD-WRT's settings are correct, as I downloaded a prebuilt VMware DD-wrt Image, however I'm unable to get the network settings right.
I either end up crashing the entire physical network in the house, or it just doesn't function.
We have a Huawei VDSL2 Spark modem in the lounge, which serves as the DHCP server for the house (Something I want to keep, even with DD-wrt) however the host PC, and most of the good stuff I have, is connected via a Technicolor TG582n, that we decommissioned when we Upgraded to VDSL, and seeing it's still a good modem, I'm using it as a router, but the DHCP is switched off, so everything connected to the TG582n gets the IP from the Huawei in the lounge.
What I want to do, is the Host PC (Windows 7) is connected via Wifi, to the Technicolor, and the onboard Ethernet port is freed, up as I want the output of the Ethernet to be that from DD-WRT, so I can connect it via crossover to my ATA box, because DD-wrt provides an option to use a VPN to connect, where as before I had used connectify, and I had to keep the computer constantly connected to the VPN, and Connectify was full of bugs, and I wasn't prepared to pay for full because I'm already paying the Nexus (VOIP) phone bill, and VPN hosting.
I'm unable to set it all up, and I've been trying for days, and I've been literally loosing sleep over it.
What I need to do is this.
I need the DD-WRT virtual device to have an IP from the Huawei modem in the lounge, so I've got a WAN source, without crashing the whole physical network, If I can access the interface on all PCs within the physical network, that will be a plus, and the Ethernet port on the Desktop needs to be able to output DD-WRT, so I can connect the lead on the ATA, which needs to be constantly connected to the SA VPN, so my phone line works. Yet again, without affecting any of the devices physically attached to the Huawei, or Technicolor devices. The network's crashed so many times, by my attempts this is a last resort.
Here is a diagram of what I'm trying to achieve. It's a rough copy, so I hope someone can understand it.
