Hi. Another "issue" i experienced with chilli 1.2.x until 1.2.9.

Sometimes (and i don't know how-to reproduce it), when a client tries 
to browse on internet, instead of being redirected on login page, he 
receive RST from chilli.
tcpdumping the traffic, there's a flwo of SYN (client) <-> RST 

Client has correctly an IP from coova, and chilli_query listippool | 
grep inuse shows:

Unit 778 : -inuse- :     XX.XX.XX.XX : mac=00-AA-BB-CC-DD-EE 
ip=XX.XX.XX.XX age=0

the "age" is incremented every by one unit, but when reach value of 
2,3, sometimes 10, is resetted to "0".
Those client experience the behaviour SYN-RST.

This seems happen randomly and with different clients. Other clients 
are able to browse without any problem.

I have to restart chilli daemon in order to make it works.

Anyone can explain why this happens and how to fix it?

Thanks a lot.
