Morning all
I have a situation where I need to add a VPN server or device to our network to facilitate iPhone (and other handset) connectivity to Exchange. Unfortunately, it’s not that straight forward as I have some caveats as well as security concerns over this.
I want to have the VPN server on a separate internet connection to our main company one. The main connection has a complex Sonicwall Firewall and VPN device on it both of which are on managed service contracts and hence cannot be altered. The Sonicwall VPN device uses a proprietary protocol which (surprise surprise) does not work on the iPhone. As far as I can find there is no app to facilitate this either.
I thought it may be possible to implement a Linux box to act as the VPN server, using a spare separate internet connection we have, that is also connected to our main comms, just as a backdoor option. And I think this is my main question….
Can I set up a linux box (or other machine) with a different gateway address (a firewall that I do have scope to change) to that of our exchange server (and hence all other servers and machines in the company) and still get VPN connectivity through that to Exchange? I’m sure I read somewhere that this would not work as the server has a different gateway address.
Alternatively is there a different method? I have a plethora of spare machines, xp pro etc. and I’m happy to install a linux box.
Any help gratefully received, thank you all.
