Welcome! You’re undoubtedly reading this because MSN provided you with the Arescom NetDSL 800/860 DSL modem, and it won’t do something that you’d like it to do. You can’t disable the firewall, you can’t forward ports, and you can’t share your internet connection without buying another router. Well, search no more!!! Herein, you will learn how to do these things, and more.
Before I get any further, I must express my thanks to “tommy2guns” from the broadbandreports.com msn forums. T2G is credited with identifying the J3 Console connection we’ll be using to configure these modems.
Now, go and get a screwdriver so we can get started!
The console connection located at J3 on the Arescom NetDSL 800/860 provides a serial communication connection using 3 volt levels versus standard RS232 voltage levels. A Maxim-IC MAX3232 Integrated Circuit is designed to convert 3 Volt Serial communications to standard RS232 Levels.
You can go to this web page linked below and order the “A232DB”. When ordering, be sure to request the “3 volt version” in the comments section on the order page.
Connect the circuit/cable to your Arescom’s J3 connector and to an available COM(serial) port on your PC. Hold down the space bar with “Hyperterminal” up and running (9600,8,n,1) And you'll see:
PP Boot 2.0
SDRAM size = 0x400000
Key pressed, stopping boot.
Entered console ... User request.
At the Prompt, type:
]fdw 10000 b
And you'll see password1(firstname.lastname@example.org), and password2(A12BCd3efg):
00010000 460119ea 13000100 33303539 37353430 '...F....12345678'
00010010 6e736d40 2e6c7364 0074656e 0a000200 '@msndsl.net.....'
00010020 53383248 6834674b 0000666f 'A12BCd3efg.. '
Remove and Reapply power to the modem WITHOUT holding the spacebar this time and you'll see:
PP Boot 2.0
SDRAM size = 0x400000

Press ENTER and You'll see a Password Request - Enter your password information found in the fdw dump you just performed
Then You'll See the “NetDSL>” Prompt.
The entry below enables multi user mode so more than one PC can be connected to the modem via a high-speed switch.
NetDSL>set multi_user on
The entry below forwards TCP port 4662 and UDP port 4672 to the PC at IP 192.168.1.2
NetDSL>add port tcp *.*.*.* 4662 192.168.1.2 4662
NetDSL>add port udp *.*.*.* 4672 192.168.1.2 4672
The entry below forwards a range of TCP ports from 2300 through 2311 and a range of UDP ports from 4000 through 4010 to the PC at IP 192.168.1.2
NetDSL>add auto tcp 2300 2311 2300 192.168.1.2
NetDSL>add auto udp 4000 4010 4000 192.168.1.2
In order to disable the built in firewall and forward all ports to one computer (NOT advised) enter the following commands:
NetDSL>set dmz_host 192.168.1.2
NetDSL>set dmz_enable on
Alternatively on some Arescom 800/860s DMZ isn't supported. In these cases the following commands will effectively disable the built in firewall and forward all ports to one IP by forwarding large ranges of TCP and UDP ports(again NOT advised):
NetDSL>add auto tcp 1 22 1 192.168.1.2
NetDSL>add auto udp 1 22 1 192.168.1.2
NetDSL>add auto tcp 24 199 24 192.168.1.2
NetDSL>add auto udp 24 199 24 192.168.1.2
NetDSL>add auto tcp 200 65535 200 192.168.1.2
NetDSL>add auto udp 200 65535 200 192.168.1.2
The following command enables dhcp server functionality
NetDSL>set ip dhcp on
The following command disables dhcp server functionality
NetDSL>set ip dhcp off
The following command reserves static ip 192.168.1.2
NetDSL>set ip dhcp add 192.168.1.2
The following command removes a reservation for the static ip 192.168.1.2
NetDSL>set ip dhcp delete 192.168.1.2
The following command sets the dhcp lease time to 7 days
NetDSL>set ip dhcp lease 604800
In order to change the two NetDSL Passwords enter the following commands:
NetDSL>set system user (You'll be prompted for a new user.)
NetDSL>set system password (You'll be prompted for a new password.)
In order to change the login and password used for PPP authentication enter the following commands:
NetDSL>set interface atmpvc0 user
Type in the PPP Username
NetDSL>set interface atmpvc0 password
Type in the PPP Password
That’s it! Reassemble your unit. Port forwarding, DMZ, Multiple Users, all on an Arescom NetDSL 800/860! You’re free at last!
