## SafeFire Links

### v1.3a

# Up and Running

This documentation file will help you to select one of prepared configuration files. Each configuration file has small help in the top, that will tell you what variables you have to setup to get SafeFire Links working in the required mode.

### Client configuration files

This section will help you to select a file that will give you access to internet using some Internet Provider. This internet provider can be a commercial ISP or the same SafeFire Links configured in the server mode at the other end of the link.

There are two client configuration files for most roles: CL_XXXX and OE_XXXX. First one must be used for normal modem connections while the second one (OE_XXXX) for PPP over Ethernet connections.

For details about setting up and using PPP over Ethernet see PPP over Ethernet Configuration Guide

1. CL_SIMPLE.CFG
   OE_SIMPLE.CFG

   This is the simplest client configuration possible. It has no advanced features and is intended to be used on the weak computers. For most cases we can recommend to use the following configuration, cl_ccp.cfg, instead of cl_simple.cfg. Only If you has some problems you should use this configuration.

2. CL_CCP.CFG
   OE_CCP.CFG

   This is a good configuration for a single client access. In addition to CL_SIMPLE settings it has CCP (Compression protocol) enabled that (if your ISP support this feature) will give you faster internet access through the same phone line and modem.

3. CL_MEDIUM.CFG
   OE_MEDIUM.CFG

   This is standard configuration for LAN access. It also can be used in single client mode if you need DOD (Dial on Demand) feature that is enabled here. As for LAN access it has firewall (packet filter) and NAT included.

4. CL_FULL.CFG
   OE_FULL.CFG

   This is the most enhanced client configuration. In addition to CL_MEDIUM it includes two filters: one is for DOD - so that you can select exactly what packets will trigger DOD function; and one is after-nat - so that you can filter packet stream converted by address translation.

5. CL_LEASED.CFG

   This configuration has all the features of CL_FULL, but is intended to be used on the leased lines.

### Server configuration files

This section will help you to select a file that will turn your computer into a small internet PPP server.

The options available are:

1. SR_PHONE.CFG

   This configuration can be used to make SafeFire Links answer phone calls and provide dial-up internet access. It has CCP and packet filter included. There are two authentication options: one for single-user access and one for multi-user access.

2. SR_LEASED.CFG

   This configuration file also has CCP and filter. But it should be used on a leased line. Optional single-user authentication included.
