The company I work for has 4 different office locations. At the moment interconnectivity is by using static ip's and over the internet. Every office has it's own domain and a server. I have found that company who was looking after IT infrastructure is so unprofessional that I might have to deal with everything myself. However I've found 4 packaged VPN capable NetGear firewalls which I would like to utilise at some point.

Now, my question is:
If everything works without VPN using internet and static IP's, will it continue to work next to VPN tunnel when I create one. Will I be able to set up a tunnel and than move some of the connectivity to use the tunnel partially, while keeping everything usable in the meantime?

 

I have one IP per site. So basically if for now I'll get 2 extra IP addresses for 2 sites and create a tunnel the rest should work as normal and allow me to partially move the whole traffic to the VPN channel? It is still long way ahead as the company who deployed the network in all the branches decided it's a good idea to use the same subnet and same ip range for the networks.

 

Yeah I will make all the remote networks VPN ready before joining them to our main network. I have some servers that can be and should be moved to head office first. That should make the subnet change easier on remote networks. When they're ready I'd like to start moving them to VPN channel as trusted domains and when that's done start merging the domains. I would like to keep current remote access solution active until all branches are connected via VPN. I'm using BT as ISP.

I want to implement VPN on Firewall level as I have the hardware. Can ADSL router act as a gateway for VPN tunnel and Internet Gateway for local network at the same time?

Thanks for your help Sparky

 

At the moment I have 2 units of NetGear FVS318 linky. Routers are those provided by BT Netgear DG834G linky.

 

By the time I'll sort the network out I am sure I'll be able to get a decent router. However, looking at the specs I am wondering if it isn't what I am after:

 

Thanks for your help Sparky.
Seems like I can't avoid working over the weekend then

 

You would be better having something better at your HQ.. I presume (didn't read all the thread - oops) your HQ is essentially the main connection point with your other offices being leafs on your VPN connection, if so, use the small routers at the leafs, and deploy a dedicated VPN server at the HQ..

I've used:

NetGear SSG 20's for leafs in the past and Astaro ASG servers 110s for leafs and 220's/320's for HQs..

Both dead easy to setup..

On a side note, I should really read threads more, but I'm job surfing at the moment
