Hi -
We've spotted a problem in between a Kannel GW and CMG SMSC. A firewall in betwwen starts blocking packets from Kannel to the SMSC roughly 2 minutes after a connection is established. Kannel recovers from this situation 5-7 minutes after firewall starts blocking. The keep alive parameter in .conf file is set to 120 seconds.
When the connection is blocked the bb logs the 31 messages but never receives an ACK back. It seems like the bbox keeps trying to send the 31 messages but wouldn't do anything if it's not acked. 5-7 minutes after bbox logs an error about a connection time out and initiates the connections again.
I wonder how's that keep-alive parameter is interpreted? The connections stay broke well after the 120 second duration.
thanks a lot,
