Seon Proxy is the solution to connect your internal OFTP station to the external internet.

Due to the fact that internet is often not accessible from internal stations AND internal stations are normally not available from external internet, Seon Proxy offers a secure solution to interact with the global internet without offering direct access of the OFTP station to the offending internet.

== Involved programs ==
The Seon Proxy consists of two parts:
*Seon Proxy: the program communicating to the external internet
*Seon Proxyclient: the program communicating to the internal network

The external communication is completely free in configuration on which port and device it listens. The internal proxy client is capable to forward incoming calls to a given internal service reachable via TCP/IP. This may be on the local host or even on another different station.

== Common situations ==
Some situations are common sense of security and offer a wide range of network implementations.

=== Expose a single port to the internet ===
In order to listen on a specified port on a single IP address in the DMZ (de-militarized zone), the Seon proxy can be installed in this instance in order to forward OFTP data to an internally connected proxy client.

=== Forward internal OFTP data to the external internet ===
When connecting to the outside world over a single point of connectivity, the Seon Proxy constellation will solve this situation.

== Licensing ==
Seon Proxy is licensed via a license file at the Seon Proxy (not client) side: only one license is needed to keep the system up and running. This license is based on an Seon Proxy ID on the proxy server side, which can be easily obtained via a command line parameter:
dmz:~ # /opt/seon/seon_proxy -L
Seon Proxy ID: '''c6bc8d9b37c5e36333a41acdda653aaef7fd4a00459eeb32a8a41059e23017c8px'''
This Seon Proxy ID is needed for license generation, which can be done for test purposes on the website at [http://www.seon.de/key http://www.seon.de/key].

The valid license will be searched by default at
/etc/seon_proxy.lic
but an alternative location can be given with the commandline option "-l":
sles11-base:~ # /opt/seon/seon_proxy -l /usr/licenses/seon_proxy.lic

== Seon Proxy ==
All external communication is done via the Seon Proxy. This daemon runs normally in the background without any interaction. It's optimized on size and speed. No logical operations are implemented here, so no OFTP operations are located in this securely separated location.

=== commandline options ===

License options:
-L: print out Seon Proxy ID (basis for license)
-l <license file>: point to readable license file (default: /etc/seon_proxy.lic)
</pre>

== Seon Proxyclient ==
The Seon Proxyclient communicates with the Seon Proxy via a single given TCP/IP port. All internal OFTP communication traffic is routed over this internal daemon.

 === Behaviour ===
 The Seon Proxy searches for a valid license for startup. This is searched at the location given with the parameter "<code>-l</code>" or at the default location "<code>/etc/seon_proxy.lic</code>". If something is wrong with the license, the actual Seon Proxy ID will be printed out with a message that the license file (with location) is invalid. Example:
   dmz:~ # /opt/seon/seon_proxy -l /tmp/invalid.lic
   ERROR: invalid license found in '/tmp/invalid.lic'! Please obtain a valid Seon Proxy license for your Seon Proxy ID:
