The ProxyServer Wizard
The following steps will guide through the installation and setup of your ProxyServer.
Step 1: Select the Device you Wish to Configure
ProxyServer Wizard
servers which will be displayed in the device list. You can click the “Refresh Device List” button to update this list.
The first thing you must do is select the ProxyServer that you will be configuring from the Device Name list.
Click Next to continue.
will automatically check your network for available ProxyServer
Step 2: Set the Device’s IP Address and Name
The next thing you must do is give your ProxyServer an IP address on your network. This is NOT the IP address from your ISP but the local, internal LAN IP address.
Note: Please Pick an IP address that won’t conflict with any other PCs or devices on your network.
The first three octets of every device or computer’s IP address on your network should be the same. ProxyServer Wizard will help you by automatically detecting the IP address of your computer and set the first three octets for you. You need only decide the last octet.
When you are finished, click Next to Continue.

Chapter 2 - ProxyServer Wizard
Step 3: Input your ISP Information for Internet Access
The next thing you must do is input your ISP (Internet Service Provider) information which will be used to dial-up and login to your ISP when your clients use their Internet applications.
Telephone Number
TA
Enter your ISP’s telephone number in the Telephone Number field. Note: If in your office or company you must dial a number to get an outside line (For
example this is often the number “9” or “0”), you should enter the number plus a “w” which will instruct the ProxyServer to wait until a dial-tone is received before dialing. For example the phone number 555-2323 which uses 9 to get an outside line would be entered as 9w555-2323. The ProxyServer also supports commas which function as delay variables. So our example number could also be entered as 9,,5552323. Each comma will provide around a 3-4 second delay.
Note: ISDN TA Setup
If you would like to bundle your two ISDN B-channels together, you need to enter the two phone numbers in the T elephone Number field. Usually ISDN TAs support either the “+” or “&” command so when entering the phone numbers you can enter them as either, for example, “555-2323 + 555-2121” or “555-2323 & 555-2121”. If your ISDN TA doesn’t support “+” or “&” you should see your ISDN TA user’s manual to see how it is possible to enter the two phone numbers.
!!! Extremely Important !!!
Please also make sure you read the ISDN TA Setup note when you get to the “Select Modem and Baudrate” step of
ProxyServer Wizard
.
User Name
Enter the user name of your ISP account in the User Name field.
Password
Enter the Password of your ISP account in the Password field and then re-confirm it be entering it again in the Password Verification field.
When you have finished, click Next to continue

ProxyServer User Guide
Step 4: Input your ISP’s DNS Server IP Address
Enter the DNS Server IP Address provided to you by your ISP. This information is usually provided to you with the information package given to you by your ISP. If you can’t find your ISP’s DNS Server IP address your easiest solution is to contact someone at your ISP and ask them for their DNS Server IP address.
When you are finished, click Next to continue.
Step 5: Select Modem and Set Baudrate
Enter the modem that you are using and the baudrate (i.e., the speed of communication between the ProxyServer and your modem or ISDN TA). This is a very important setting and determines the communication between your ProxyServer and modem.
Modem
You can use the Select Modem button to select your Modem or ISDN TA. This setting will configure the initial string in the ProxyServer so that it will know how to communicate with your modem. If you are using an analog modem but do not see your modem in the modem selection list, in most cases the default setting of Standard Modem will work.

Note: ISDN TA Setup
Chapter 2 - ProxyServer Wizard
TA
!!! Extremely Important !!!
If you do not see your ISDN TA listed, you need to enter the initial string for this TA in ProxyServer Manager’s Modem Settings menu. Once you have finished
Wizard
Modem Settings for instructions.
press the Run Manager button and refer to Chapter 3 - ProxyServer Manager :
ProxyServer
Baudrate
In the Baudrate field select the DTE Speed (i.e., the speed of communication between the ProxyServer and modem or ISDN TA) Normally this can be about 4 times the speed of your modem for 4 times compression modems.
Note: The absolute maximum you should set the baudrate for a given port on your ProxyServer is 4 times the speed of your modem. If you set the baudrate too high, the ProxyServer may not be able to dial-up a connection. For example if you have a 14.4K bps modem, the highest you should set the baudrate is 57.6K bps. Also note that due to ISP connections and phone line conditions this maximum speed is theoretical and not guaranteed.
When you are finished, click Next to continue.
Step 6: Verify the Setup Configuration
The settings that you have just configured will be summarized here. Please check to make sure that all the settings you have entered are correct.
If you see that you have configured a setting incorrectly , click Back to go back to the screen with the mistake and correct it.
When you are satisfied with your configuration, click Finish to save your configuration to the ProxyServer and complete the
ProxyServer
Wizard.

, is
Server Subnet Mask
The ProxyServer Subnet Mask can usually be left as it’s default entry 255.255.255.0.
External (Port) IP Address
The External (Port) IP address is the IP address that is given to you by your ISP. An IP address is often dynamically assigned by your ISP (i.e., it changes every time you log­on). To have this address assigned by the ISP leave this field as it’s default entry 0.0.0.0. If you have been given a static IP address by your ISP you can enter it in this field.
DNS Server IP Address(s)
The DNS Server IP address that you entered in ProxyServer Wizard will be displayed here. The ProxyServer supports multiple DNS Servers which can be entered here.
Allow connection to be established by dial-in
This option is usually employed for the Virtual Server function of the ProxyServer . (Please see Chapter 3 – ProxyServer Manager : Virtual Server). This option does NOT mean remote access as the ProxyServer does not support remote access. However, the ProxyServer does support the function of letting your ISP dial-in to the Internet Access to establish the connection. If you would like to allow the connection to be established by dial-in, enable this option.
14
Chapter 3 - ProxyServer Manager
Callback Telephone Number
If you have selected the “Allow connection to be established by dial-in” option, you can use the Callback Telephone number function of the ProxyServer . You can use this function if you do not want to have a permanent connection to your ISP up all the time and your ISP will not support the telephone charge to dial-in to your network when people try and access your static IP address or domain name. After you have entered your ISP’s phone number in this field, when anyone calls up the ProxyServer, the ProxyServer will automatically hang up and dial the ISP’s phone number establishing the Internet connection. For information on the purpose of this function please see Chapter 3 – ProxyServer Manager : Virtual Server.

For example if you have a 14.4K bps modem, the highest you should set the baudrate is 57.6K bps. You should also be aware of the fact that since some ISP connections and phone lines are not of the greatest quality , this theoretical maximum speed is not attainable and you should set the baudrate at a lower speed.
ProxyServer Wizard
will be displayed here.
Select Modem and Modem String Setting
The most important modem string is the initial string because the ProxyServer uses it to establish communication with your modem or ISDN TA. The modem initial string displayed here was configured automatically when you selected your modem or ISDN TA in ProxyServer Wizard. If your modem is not listed in the Modem Selection List, the
Standard Modem selection will work with most modems.
Note: ISDN TA Setup
!!! Extremely Important !!!
Unfortunately, unlike most modems, ISDN initial strings vary between different ISDN TAs and there is no “Standard ISDN TA” initial string. If your ISDN T A is not listed in the modem selection list you must find out what your ISDN TA initial string is. Your ISDN T A’s initial string should be listed in your ISDN TA user’s manual. There are probably many initial strings listed for your ISDN TA. The one you are looking for is Asyn-to-Syn PPP (Asynchronous to Synchronous PPP). You can enter this initial string if you would like to use only one channel of your ISDN TA. If you would like to bundle both channels of your ISDN TA together, you need to use a different initial string called Multilink-PPP. For example, the initial strings for a Zyxel Omninet ISDN TA are:
1) ATB40 : Asyn-to-Syn PPP initial string
2) AT&J3: Multilink-PPP initial string
You should also verify that your ISDN TA supports the Dialup string A TDT. Most ISDN
16
Chapter 3 - ProxyServer Manager
T As will support ATDT and usually the rest will support ATD or A TDI. Please also note that to bundle the two channels of your ISDN TA together, you must
enter the two phone numbers in the T elephone Number field of the Modem settings menu. See Chapter 3 – ProxyServer Manager : Modem Settings.
Enable Login Script
With the login script you can manually input the communication between your Modem and ISP. Most ISPs support automatic PPP negotiation but if your ISP does not support automatic PPP negotiation you will have to enter a login script. You can also use the login script to enter a second backup ISP or write a script that makes the ProxyServer redial until a successful connection has been established. To write a login script, first click on the Enable Login Script option box. The ProxyServer login script commands and some examples are provided on the next few pages.
