Hi all i am linking up two offices so that i can run a program remotely using 2 d-link g604t routers, what would be the best and easiest way to get it running and if i need extra software what is the best one to use.

Thankyou for your time and input

It sounds like you need a VPN between the two offices.
You will need routers with a VPN feature. I don't know if your current routers have this feature off hand.

Do you have fixed IP addresses at your offices or are they dynamic?

Thankyou I have  DSL connections that are dynamic as for the VPN i know the D-Link does but the other I more than likely think not as it is a basic DSL modem with router.

I would advise that you look at the options of getting static IP addresses each end as it wil make the VPN connection far more reliable. If you don't then you will probably have to reconfigure the routers whenever either IP address changes.

OK, Once the ip addresses are made static I need to have sage running over the network so that it works in realtime for invoicing etc. What method would be the most suitable approach for this, As i would need to see their network to map it out

Thankyou for your help in arrears and in advance.

You would establish a VPN between the two offices and then it would appear as though both offices are on the same local network.

You can use D-link and similar products for the VPN but they are not as rubust or reliable as for example a Cisco PIX but they are a lot cheaper. If you don't mind having to switch both routers off and back on, on occasion then they should be fine but if the link between offices is very important to you I would advise going for something like the Cisco PIX for extra reliability.

OK, well as you can probably tell i am quite new to networking over wan using VPN if I get static addresses then install a server primarily for the sage side would that be the best alternative as it covers all from accounts to payroll then assuming thats ok i can go to the new office and install sage their but with a mapping to the main office to locate the accdata folder where all the shared info would be kept. Thankyou for any input it is greatly appreciated as security on this network is also of great importance.

Yes that should work however bear in mind that the maximum speed the remote office will be able to transfer at will be the upload speed at your main office which is often lower than your download speed on ADSL or DSL lines.
I suggest contacting Sage and asking if the software will work acceptibly over this slow speed connection.

Hello there
sorry i haven't been around but have still being having trouble with this server, Basically I have set up a server with nothing on it except windows server 2003 then enabled RRAS I have that connected into the G604T D-Link router which obviously is connected to the internet, The other office however has 3 computers running windows XP professional connected to a ADSL router but when i go to connect from the remote office using the account credentials it still wont allow access giving an error code that the username and/or password is incorrect. Please please someone tell me where i am going wrong before I scream

Thankyou once again for your input

So you have Windows 2003 as the VPN server?
I assume you are using the PPTP type VPN?
Have you redirected port 1723 to the VPN server in the D-Link configuration?
You also need to forward GRE (IP protocol 47) to the VPN server. The D-Link wont have an option for this. If you turn on PPTP Pasthru it may do it but it may not (the option is intended for outbound traffic).

To make this work you often have to use the VPN on the Internet router or have a better router which allows you greater control on what you forward.
