1. Overview Thecus Technical Support stuff may need to logic the NAS for checking system. Therefore we need your help to publish your NAS on the internet. 2. Setup Thecus NAS on Internet There are many ways to publish your Thecus NAS on Internet. No matter you have public fix IP or dynamic IP, we would recommend you connecting your NAS to an IP router. One of the most benefits is IP router is also a simple firewall itself and could interdict most internet attacks. Secondary, no matter you are using ADSL, ISDN, HTTB, Ethernet, or Cable Modem, you only need to modify your IP router s setting and it is no necessary to do modify on NAS. After you connecting Thecus NAS to IP router, there are two easy ways to publish it on internet, one is DMZ and another is port forwarding. 2-1 Demo with DD-WRT DD-WRT is a famous open source firmware for Router, here we use an IP router with DD-WRT for demo. Configuration of the Thecus NAS WAN: 192.168.1.100 LAN: 192.168.2.254 Connect WAN to your IP router. 2-1-1 Setup DMZ for Thecus NAS In computer security, a demilitarized zone, named after the military usage of the term and normally abbreviated to DMZ. The purpose of a DMZ is to add an additional layer of security to an organization's Local Area Network (LAN); an external attacker only has access to equipment in the DMZ, rather than the whole of the network. 2/12 2/July/2010
In IP router, the only setting is in DMZ session, fill in IP (192.168.1.100) and apply setting. This is the easiest way, however, we WON T suggest user to setup NAS as DMZ for security issue. We would like recommend as by port forwarding. 2-1-2 Setup Port Forwarding for Thecus NAS Setup port forwarding function in IP router, we need to open a TCP port 22 & 80 & 443 to NAS WAN IP. 2-2 Demo with Tomato Tomato is another famous open source firmware for router. Here we have a demo with Tomato 1.28 firmware. Configuration of the Thecus NAS 3/12 2/July/2010
WAN: 172.16.66.100 LAN: 192.168.2.254 Connect WAN to your IP router. 2-2-1 Setup DMZ for Thecus NAS In computer security, a demilitarized zone, named after the military usage of the term and normally abbreviated to DMZ. The purpose of a DMZ is to add an additional layer of security to an organization's Local Area Network (LAN); an external attacker only has access to equipment in the DMZ, rather than the whole of the network. In IP router, the only setting is in DMZ session, fill in IP (172.16.66.100) and apply setting. This is the easiest way, however, we WON T suggest user to setup NAS as DMZ for security issue. We would like recommend as by port forwarding. 2-2-2 Setup Port Forwarding for Thecus NAS Setup port forwarding function in IP router, we need to open a TCP port 22 & 80 & 443 to NAS WAN IP. Assume some port was blocked for security issue, we will forward port as following, 4/12 2/July/2010
Public port 8822 (Internet) < ==== > internal port 22 (NAS) Public port 8880 (Internet) < ==== > internal port 80 (NAS) Public port 8443 (Internet) < ==== > internal port 443 (NAS) 5/12 2/July/2010
2-3 Demo with Netgear (model WNR3500L) Netgear is a famous vendor of networking products. It pre-defines some service in port forwarding settings and get easy to setup. Here we have WNR3500L for demo. Configuration of the Thecus NAS WAN: 192.168.1.100 LAN: 192.168.2.254 Connect WAN to your IP router. 2-3-1 Setup DMZ for Thecus NAS In IP router, the only setting is to check DMZ server and fill in IP (172.16.66.100) in WAN setup page. This is the easiest way, however, we WON T suggest user to setup NAS as DMZ for security issue. We would like recommend as by port forwarding. 6/12 2/July/2010
2-3-2 Setup Port Forwarding for Thecus NAS In [Port Forwarding / Port Triggering] setting page, click Add Custom Service to add service. Fill in the information for port 22. Add port 80 for HTTP. 7/12 2/July/2010
Add port 443 for HTTPS. 8/12 2/July/2010
3. Tell us your public IP 3-1 Determine the public IP of your router Here is a tick that you may acquire your public IP quickly. Please connect to http://whatismyipaddress.com/ by using browser such as Microsoft Internet Explorer or Firefox, and then you may acquire your public IP very soon. 3-2 Dynamic IP and apply your Dynamic DNS If you have a dynamic IP, that means the IP may change very soon, and it will lead network disconnection. Thecus Support would only connect to your device after you tell us the new IP. Therefore, you may apply a dynamic hostname to resolve it. We suggest two DDNS provider, www.no-ip.com www.ddns.org Here is a screen shot of www.no-ip.com, you may apply an free account. 9/12 2/July/2010
After you have apply an account and a host (ex: thecushelpme.no-ip.org), please fill in the information in the DDNS session in the router setup page. 10/12 2/July/2010
11/12 2/July/2010
4. Appendix A Here is a screen shot of WAN setting. We would suggest using WAN port to connect to your router. Please check the IP, which is to filled in port forwarding session in router s setting page. EOF 12/12 2/July/2010
