target for modifying conntrack timeout value

[Richard]

Hi,

I wonder if there is a target to modify the conntrack timeout value. For
example, an established udp connection has a 180 seconds timeout value. It
is sufficient for most applications. However some need to have a higher
value. What I'd like is the ability to set the timeout value in the
conntrack.

Is there such a target already? If not, is it feasible?

Thanks,
Richard
