D-Link DSL-G604T Configuration

If you have this router, of course you want do configuration fast and simple, if you don't use alternative firmwares (for example http://wiki.openwrt.org/OpenWrtDocs/Hardware/D-Link/DSL-G604T), the best solution will configure right original firmware. I had this thing 2 years, so i'll try to help you. My firmware version is V3.02B01T01.RU.20070322, it's last russian firmware. (ftp://dlink.ru/pub/ADSL/DSL-G604T/Firmware/ADSL2+)

Password and Time

Goto Tools -> Admin and set new administrator's password, than goto Tools -> Time, choose Automatic (Simple Network Time Protocol) and set your time zone.

DHCP and DNS

Home -> DHCP

Enable DHCP Server. Full Lease Time with all nines (999999) to have longest DHCP session.

Set DNS Mode to Manual and enter DNS servers, for example i'll be use OpenDNS servers (http://en.wikipedia.org/wiki/OpenDNS):

Primary DNS: 208.67.222.222

Secondary DNS: 208.67.220.220

Then goto Home -> DNS, set DNS Relay Selection mode to Use User Discovered DNS Server Only and fill other fields with your DNS'es (i use OpenDNS):

Preferred DNS Server: 208.67.222.222

Alternate DNS Server: 208.67.220.220

ADSL

Advanced -> ATM VCC

VPI Set your VPI

VCI Set your VCI

Set your User Name and Password too.

NAT and Firewall must be enableded.

Dynamic DNS

If your ISP give your dynamic IP adress, it's good to be have an same name alltime, so good solution will be use Dynamic DNS (http://en.wikipedia.org/wiki/Dynamic_DNS). I use www.dyndns.org account, you may use other, so register at their site and fill fields with getted values. If your have your own domain name, you may of course do CNAME alias for something.yourdomain.com to youraccount.yourdyndnsservice.com.

Wi-Fi

By default wi-fi have no security, so anyone may use your internet connection as it wants, so goto Home -> Wireless. Write any name you like that Access Point will have in SSID field, then set security type to WPA and choose WPA2 only. Then choose Pre-Shared Key and write secret string at PSK String field, for example hellobitchesnobodyhacksme, attention, you should remember this, cause you will need to set this at any Wi-Fi devices, that will use your access point. Than goto Advanced -> Wireless Perfomance and enable Hidden SSID, attention that in future you will need manually write SSID at any Wi-Fi devices, that use your Access Point. That's done.

NAT and Firewall

That's the longest and must wanted part, so we start quickly:

If you use Windows, do ipconfig /all to see your MAC adress. If you use other OS, try to get MAC adress byself. Goto Home -> DHCP and type in Static IPx IP and MAC values for those machines, that need Port Forwarding. Then goto Advanced -> Firewall and set all to Enabled and set birds anywhere. Than add machines that need Port Forwarding at Advanced -> Lan Clients and finally add rules as you want in Advanced -> Virtual Server. Goto Advanced -> Bridge Filters, and check off Enable Bridge Filters.

That's the end! Good luck.
