Hi Chris I have a deployment very similar to yours. I specifically use the IMSI as the pool key only in order to always give the same IP to the phone, and solve the disconnect/reconnect/timeout issue with a Packet-of-Disconnect sent to the GGSN for the old session during the authorization stage for the new session..

Sorry this is not a GIT patch.

Here are two minor fixes to the MySQL ippool.conf file.

1) A Syntax correction for the alternative 'allocate-find' query.

2) There was an issue with the 'start-update' query updating more than it should. I am using IMSI codes as my pool-key. In the case that a phone disconnects, but no Acct-Stop is received the expiry_time is updated every time that this phone reconnects as only the NAS and the pool-key are used as update limiters.

By including at least the framedipaddress this is solved.

As both the 'stop-clear' and 'alive-update' sections are using the 3 additional qualifiers, it makes sense to use them here too. (I see no reason no to).

Chris
