Hi first of all thanks to everyone who looking into this. I have two offices in Southport in GoldCoast. I have two offices that is around 1.2km from each other, and they are approx 600meter from exchange (the black in the exchange) Im keen to establish a network connection between the two sites..... I have a server in site A with 7 laptops connecting to it in LAN, I have 5 others computers in Site B, and I would like to connect site B to site A...... (I hope to achive it so that if let says Site A's server is 192.168.0.1, laptop in site A is 192.168.0.10 to 192.168.0.20. The laptop in site B will be 192.168.0.30 to 192.168.0.40, and as soon as I turn on any computer on the site B, it is able to ping 192.168.0.1) Options that I have thought about: Options 1: TPG have 10/10 EFM for 199 dollars, so for both site it will be 199X2 per month which is acceptable. TPG does provide the Network Terminating Unit with normal ethernet interface, which I believe billion 7800n is able to use to log into TPGs network. However I don't know how to make it so that site B can connect to site A like as if they are the same network? Or do I have to use VPN to achieve that? I would perfer not to use VPN, as that mean all 5 computers in site B have to connect use VPN, and I have to setup the server on Site A to be the VPN server. If anybody able to help me set it up or can direct me to someone who can help me with it it will be greatly appreciated. Option 2: Wireless connection, using wireless antannea and receiver. I don't think i have direct line of sight but it is pretty close, and Site B is around 6 floors up, hence it is doable, however I don't have enough knowledge in setting up, would any one know any company or any person who is professional in doing such setup that I can contact? Any comment or suggestions are greatly apprecated, and please msg me privately if you are able to help me set it up, and we can discuess what fees are involved. Once again thank you for looking into this thread.
