Summary

Issue Detail
I have more than one mail and/or NNTP server. How do I set up FreeProxy to access all these servers.
Solution
Without a proxy server, you connect directly to the internet accessing your email and news servers. However, when accessing your email and news servers through a proxy server you will have to set up the connections differently. FreeProxy now connects directly to the news/email servers and the client software connects to FreeProxy. When there is more than one news/email server to connect to, you can use different ports to distinguish the different servers.
SMTP normally connects on port 25
POP usually connects on port 110
NNTP usually connects on port 119
These are conventions and the use of different ports between the client and FreeProxy does not matter. The usual conventions must be used between FreeProxy and the mail or NNTP servers.
The connections required for setting up SMTP would be as follows:
In the client, such as Outlook Express, set up 3 accounts.
For the first account, input the name of the server running FreeProxy for both the pop and smtp servers. Specify 25 as the port for SMTP and 110 as the port for POP.
For the second account, input the name of the server running FreeProxy for both the pop and smtp servers. Specify 10025 as the port for SMTP and 10110 as the port for POP.
For the third account, input the name of the server running FreeProxy for both the pop and smtp servers. Specify 10026 as the port for SMTP and 10111 as the port for POP.
In FreeProxy, you will need to create 6 port settings, 3 for POP and 3 for SMTP:
For SMTP:
Code:
Client port Server Name Server Port
1. 25 mail.ISP1.com 25
2. 10025 mail.ISP2.com 25
3. 10026 mail.ISP3.com 25
For POP
Code:
Client port Server Name Server Port
1. 110 mail.ISP1.com 110
2. 10110 mail.ISP2.com 110
3. 10111 mail.ISP3.com 110
Notice that the client port is used to distinguish the different connections,
When setting up the client, make sure you specify the name of the PC/Server running FreeProxy NOT the name of the mail server. So if the server running FreeProxy is called MYSERVER01, then in Outlook Express you would specify (for example 2 above)
for SMTP
Server: MYSERVER01
Port: 10025
for POP
Server: MYSERVER01
Port: 10110
In place of MYSERVER01, put the name of your server. The point being made here is that you do NOT put the name of the mail server (eg: mail.ISP2.com) in Outlook Express (or your mail client). The mail client would then connect to FreeProxy on port 10110 for example and that connection is redirected to port 110 on mail.ISP2.com.
In a similar way you can set up ports 10119, 10120, 10121 etc when connecting to multiple NNTP servers.
If you don't want to use the ports suggested above for the client ports (eg 110, 10110, 10111, 10025, 10026 etc) you can really use any port number as long as its not a well known ports used for something else. Don't use 23 and 21 for example, these are the standard ports for telnet and FTP. In fact don't use any ports 1 to 1024. Use port numbers in the 10000-65000 range. When connecting from FreeProxy to the mail server you MUST use the correct port (25 or 110 or 119).
