todo
----
1. Add dynamic port allocation depending on the traffic

2. Add static cache entry for each expired table entry

3. Default gateway for port is added in roucon.ini

4. Instead of recomputing csum can't we add and subtract modified
   parameters.

5. When allocating a new physical port check for pending packet to
   send in addition to pending bytes. Here we need to check receive
   throughput also.

6. Add priority check for each port.

7. For allocating application ports seprate functions are to be
   called instead of the current scheme. (TCP function is already
   there, UDP we need to write function).

8. Should we drop the packet which is not to be proxied.

9. Should we record the servers, local clients, applications.

10. For Rlogin start allocating port from 500 to 1023.

11. TFTP have special handling to support dynamic ports.
