Satellite & VPN

Hi,

I've just moved to an area with very poor broadband coverage (not much better than dial-up speed most of the time), my wife is aiming to start working from home via vpn from september and I was thinking of taking a look at satellite broaband through maybe tooway but am concerned about possible latency issues - anyone have experience of using vpn over satellite??

Thanks
 
VPN will still work on Satellite but, depending upon the task you're performing and VPN setup being used, it could be affected by the limits of related platforms. VPN needs a high-bandwidth, low-latency network with fast upstream speeds to work properly.

The latest Satellite solutions are much better at delivering this but they still suffer from high-latency and often have heavily throttled connections that can cause their top speeds to fall away dramatically after you consume a certain amount of your usage allowance.

Some Satellite ISPs also fail to provide support for VPN in their service terms and might also adjust IP traffic in a way that can make it more difficult than it should be to establish a VPN connection. In this instance you need to check whether the satellite operator supports the service before you sign-up.

Usually happens with providers that don't give you a real IP address, but put you within a NAT network. This can cause major problems with VPN and NAT traversal.

Tooway looks good as it appears you get a real IP address (and can have multiple), as well as some providers being able to offer UK-based IP addresses towards the latter half of the year.

This is incorrect where Tooway is concerned as a networking specialist I have tried all forms of VPN over the Tooway consumer and their Pro services which are supposedly supplied with a static IP address which is also not quite correct.

It is the latency on the network, and the fact that Tooway actively downgrade any form of VPN traffic as they don't want it running on their network. Tooway quotes a general latency of 650ms but I have not seen it less than 1150ms, and it needs to be much much less to even get a connection, let alone good speed of data over that VPN.

The final point here is also, that Tooway runs some sort flaky TCP acceleration from their modem to their network hubs, which if you encapsulate data inside a VPN you lose the benefit of this, which means your VPN data will run even slower.

I am told though that a company called Overland Networks who have developed some clever software that overcomes a lot of these these problems and which will work over all satellite links which also applies some sort of QoS to VoIP and Video as well as it allowing remote access to any equipment connected to the local modem, which is really useful.
