Hi,
I'm looking for a way to keep a GSM connection up during the time to make an ftp download. The problem s that the DDR ACL is taking this flow in account but when the dialer idle-timeout expires on the Cellular interface, then the GSM lnks goes down... If I don't setup the idle-timeout, the links stays up for ever...
Thanks for your help

Does your dialer include configuration of a dialer group? If so is there a corresponding dialer-list? If so what does the list define as "interesting" traffic. Proper definition of interesting traffic is the best way to get the link to stay up. When the dialer sees traffic going through that matches the definition of interesting traffic then it resets the idle timer which results in the link staying up.

Hi,
I found where was the problem. The Cellular interface doesn;t work as a dialer (even with all the dialer commands...)
I created a dialer interface, put the Cell in this dialer group, and launched a "debug dialer packet".
The think I forgot to say is I have a crypto map on the Dialer interface, and as soon as the VPN is up (DDR ACL is ok) then, the dialer idle-timeout wasn't reset because all traffic is then like : SA = dialer interf and DA = public IP of the remote ipsec peer
...and of course didn't match the DDR ACL.
But then it works like a charm.
I even successed to setup NAT on all of this to hide the LAN subnet inside the VPN.
If someone is interested by the config... let me know.
Thanks Rick ;0)

Use the following command on the cellular interface:
dialer idle-timeout 2147483

dialer idle-timeout 0
to make it infinite up
