General Server-Side Requirements  

Firewalls 

Englishtown ASP is compatible with all firewall configurations that enable users to access the 

Internet using ports 80. Although not a requirement, it is preferred if the firewall is configured to 

allow streaming media as well.  If Englishtown for LMS is deployed, Englishtown’s school 

content servers must be able to communicate with the customer’s LMS server over port 80 in order 

to send student data back to the LMS. 



Proxy Servers 

Englishtown uses Internet technologies that are fully compatible with proxy servers. In order to 

access Englishtown from a client using a proxy server, port 80 must be open bi-directionally, and 

port 443 (for HTTPS traffic) should be open inbound. In most cases, this is the standard 

configuration. In addition, with Microsoft Proxy Server the client should be able to authenticate 

using Basic Authentication (clear text authentication) or the client workstations must have MS 

Proxy Client installed to handle the proxy server authentication.  

 

In the event that a client is having trouble accessing Englishtown through a proxy server, it is 



possible to bypass the proxy server using a static route for the Englishtown servers with the 

gateway set to be the firewall or Internet router. This will only work, however, if the Proxy server 

is not set up with separate inside and outside subnets. 

 

Configuration Notes for Corporate Networks  

Each corporate network has its own special configurations and security issues. Some points of 

Englishtown site are affected by these configurations, and the possible solutions vary from 

customer to customer, depending on the firewall and/or proxy configurations. 

As a general guideline, we can list the following points: 

-

 



All users must be able to “download” and “execute” ActiveX controls in their local 

workstations. The most part of these controls are installed on the first access, but periodically 

new controls (or new versions of old ones) can show up on the school site. 

-

 



If ActiveX “downloads” are blocked, but the user is still able to “execute” ActiveX controls, a 

manual installation can be performed. 

-

 

The network protection systems (“firewalls” and “proxies”) must be configured to allow sound 



files “download” (wav, asf, wmf, etc.). Audio streaming permission is not needed. 

-

 



The Englishtown students must have access to all internet sites with names ending on 

“englishtown.com”, despite its host names or IP addresses. Modern firewall systems usually 

allow this kind of “domain-based” configuration, instead of old style “IP-based” access 

configuration. 

-

 

The firewall system must allow “host redirection” and “address redirection” inside 



“englishtown.com” domain. 

-

 



The firewall and proxy systems must be configured to allow access to ports 80 and 443 of all 

Englishtown hosts (from inside to outside). If possible, access to port 1709 of external 

Englishtown hosts should be available as well. 

-

 



 There is no special configurations for “return connections” (connections made from external 

hosts to internal client workstations). Usually the proxy system itself takes care of this. 

Firewall systems must allow “established return connections” from Internet to Intranet, as 

usual. The general guideline is: if you can simply browse Englishtown site pages, you are 

already done. 

-

 



The Englishtown Virtual Classroom (i.e. the Centra Symposium) client is compatible with 

packet filtering devices. Firewalls do NOT have to be reconfigured to support the EVC.

The Englishtown Virtual Classroom client uses port 80 for HTTP events and port 1709 for 

audio, application sharing and user interactions. If port 1709 is not available (because, for 

example, the client is behind a firewall), the EVC client will automatically use tunneling over 

HTTP (port 80). 

 

Englishtown Virtual Classroom / Centra – Manual installation Process  

In some corporate networks, the users do not have enough privileges to install the EVC/Centra 

client automatically in their workstations. 

In these situations, a manual installation can be done. If the user (or corporation) already has the 

“SetupJ.exe” installation file, we recommend its installation in forehand, BEFORE the process 

described below. 

The user MUST have rights to install applications locally (usually, the user must be a “power 

user”). Installations made under different user profiles (even as “Administrator”) will not work as 

desired. In the same way, installations made using the “Run As” feature from Windows 2000 or 

XP will not work. 

The installation process is the following: 

 

1)



 

If the user already have the “SetupJ.exe” file, install it 

2)

 

If the user is prompted to reboot your system, do it. 



3)

 

Go to Englishtown web site, and log in. 



4)

 

Click on the “Technical Check” link, and follow the instructions. Perform all tests (with 



the exception of “Voice Chat”), until you get the “Englishtown Virtual Classroom” test. 

5)

 



During the EVC test, the user will receive the window shown below. Click on the link 

“CentraOne setup”. 

 

 

 



6)

 

After the user receive the window below, he or she can download the “SetupJ.exe” file and 



install it.  If they have already installed the Centra client at step 1, the will not you don’t 

need to download and install again. Click on “Launch CentraOne” button.

7)

 

If the Centra client loads and executes successfully, users will receive the warning window 



shown below. Click on “Yes”. 

 

 



 

8)

 



You must receive the following window. Users should wait while the “Centra Client” 

version is updated. 

 

 

 



 

Please note the following: 

 



 



After the update, the EVC should open normally. 

 



 

This procedure should be executed only once –  the first time a users tries to access 

EVC. 

 



 

For questions or other information, please contact Englishtown directly.

Implementing Englishtown as an ASP Solution 

Overview 

Access to Englishtown’s web-based training in an ASP solution is provided on a licensed 

subscription basis.  License codes provide individual users with unlimited access to all self-study 

materials as well as 24-hour live, teacher-led, discussion (if the teacher-led option is chosen).   

 

In an ASP Solution, Englishtown is responsible for hosting all content, student data and 



performance tracking.  Student access to the Englishtown training requires Internet access, either 

directly from the user’s desktop or through a web-connected Intranet server.   Students will log-in, 

select courses, complete course work, take exams and track their results on the Englishtown 

servers.  Manager reports will be accessible on the Englishtown site.   

 

Implementation Specifics 

Englishtown’s proposal to implement an ASP solution at a customer would include the following 

steps: 

1.

 



Develop Co-Branded Site:  Englishtown would create and host an exclusive, co-branded 

Englishtown web site for use by the customer’s employees during the term of this 

agreement.  The estimated completion time for this is three weeks.   

2.

 



Distribution of Self-Study and Teacher-Led License Codes:  Englishtown would 

provide the customer with a series of license codes which would be used by students to 

access training services on the Englishtown site.  These license codes would have to be 

distributed to individual employees by the customer.  We estimate approximately two-

three weeks for this process. 

3.

 



Build-Up Period:  Englishtown and the customer would agree on a “build-up” period for 

students to enroll and begin studying.   Typical build-up periods run from one to three-

months, depending on the number of users.

Englishtown Integration with an LMS 

Overview 

For organizations with a learning management system (LMS) in place who want a single entry 

point for all of their corporate training, we provide an easy integration using industry standard 

protocols.  Englishtown can be integrated with any AICC-compliant LMS, such as Saba or Docent.  

 

Under the integrated model, the customer hosts the LMS on one of its servers.  The LMS serves as 



the primary e-learning ‘portal’ for and handles functionality such as the course catalog, user 

registration & authentication, tracking and reporting. 

 

Please note that in an LMS integration, Englishtown continues to host the Englishtown school, 



including all self-study and teacher-led courses.  Students launch Englishtown courses from the 

LMS course catalog and are automatically logged into Englishtown through a unified log on.  

Upon completing a unit of study in Englishtown, relevant student data is passed back to the LMS 

using the AICC industry-standard protocol. 



 

Project Estimates  

Englishtown will provide the technical resources needed to integrate the Englishtown School with 

the LMS using the AICC protocol.  Billing for the cost and expenses incurred in this work would 

be in addition to the cost of any user licenses or content-access fees charged by Englishtown.
