Services for Companies

 
  You may have a company office located in a country which limits the websites you an access or Internet services you can use, such as Skype.
Perhaps you have concerns that your Internet traffic is being monitored to get access to company documents or emails.
We've come up with some services we can provide to overcome these problems that you could implement once on your server or router, rather than on each individual's PC.

 
 

Server-To-Server VPNs

 
  Windows Servers and many £200 routers, such as those made by Draytek, can make VPN connections to our servers which then stay connected indefinitely, reconnecting whenever there's a dropout.
Using routing rules you can determine how much of your Internet traffic uses the VPN connection and how much goes out to the Internet as normal. A local unblocked website would be quicker to access directly than looping via London.
You could choose to just send your SMTP email traffic or DNS lookup requests over the VPN.
If you have a Windows 2008 server you can make an SSTP VPN connection which looks like a normal connection to a secure website and so hides the fact that you are even using a VPN connection.

We charge according to the number of users you have on your LAN and how much traffic you intend to send over the VPN. The next 2 sections are about Email and DNS services we can offer, either directly or over a VPN.
Use the following web-form let us know what service, or combination of services, you're interested in or you can email us directly at info@rhebus.com

Email Services

 
  Simple Mail Transfer Protocol, or SMTP, is the standard way to send out emails.

There are 2 problems with this:-

1 - SMTP is not encrypted so that anyone monitoring your Internet traffic will be able to read the contents of the emails you send.

2 - You may be connecting to the Internet from a place which the regular SMTP server you use doesn't trust, and therefore refuses to accept your emails for sending

Our VPN servers contain an SMTP server which you can access over the VPN. This means that, not only are your emails strongly encrypted, but anyone monitoring your connection won't even be able to tell that you're sending any emails.
If you have added SMTP Server Access to your VPN subscription then our servers will accept your emails however you connect to the Internet.

We use the powerful SMTP server provided by Arrowmail - more details here.
A single user sends between 300 and 500 emails per month, on average, so the cost for SMTP access for up to 1000 emails/month is £2.95/month. If you wan't to send more then here's the table of charges:-

If you are a company with your own network you might just want your SMTP traffic to pass over the VPN and have all your other Internet traffic to go straight out onto the Internet as normal.
This is easy to setup by editing the VPN connection properties so that you don't use the VPN as the Default Gateway.
 

Truthful DNS Server

 
  Humans use human-friendly names to access resources on the Internet, such as the website www.google.com.
Your computer uses computer-friendly numeric IP addresses to actually connect to the Google website, such as 209.85.227.99
Something is required to translate between the website's human-friendly and computer-friendly addresses, and that something is a Domain Name System server, or DNS server. There are DNS servers on you office LAN, in your home network's router and at your ISP that your PC is using right now to get around the Internet.
Assigning which DNS server your PC uses is done automatically and out-of-sight, as are the 100s of DNS lookups that your PC performs against its DNS server while web browsing or checking your email.
You could spent you whole Internet life without knowing anything about DNS - many people do.

But sometimes DNS servers tell lies!

For example, if a country has instructed its ISPs to prevent users accessing horse racing and betting sites, then when a user types into their browser: www.bet-on-horses.com and their PC asks the DNS server for the IP address of this site, the ISP's DNS server purposely gives the wrong answer:-

How web-sites can be blocked by your ISP's DNS servers giving the wrong answers

The "wrong answer" might take the user to a warning webpage explaining why they have been blocked, or the IP address returned might be a "black hole" which just gives a "Page not found" error.
If the user can find out what the correct IP address is they can get their PC to access the correct site without needing to use a DNS server but this requires some technical know-how and it's not uncommon for the IP address of a particular site to change on a regular basis which makes fighting this "DNS censorship" a pain.

Another concern is that your local DNS server may be logging all the lookups requests you send it, so there could be a record of all the places on the Internet you've visited.
Security and privacy are, therefore, other reasons to use our DNS servers.

You can use the "truthful"  DNS servers, located on our VPN servers, when you subscribe to one of our VPN services. However, you may not need a VPN connection and just need access to a truthful DNS server and so we've made our DNS servers available to connect to directly over the Internet.
Our DNS servers will only accept connections from IP addresses it knows about, otherwise we'd be swamped with DNS request from all over the Internet and also not have a viable business model.
So, if you have a fixed IP address that can be added to our access list, you can access our DNS servers for £2.99/month.

If you don't have a fixed IP address you can still access our DNS servers by first making a VPN connection to our servers. You could set your computer not to use the VPN as the Default Gateway so that only DNS traffic will travel over the VPN.
