Two minutes (or one minute if there hasn't been a reply from the other side).

You should be able to do it by adding the following tags to the <system> section of config.xml (order is important):

<earlyshellcmd>/sbin/ipf -D</earlyshellcmd>
<earlyshellcmd>/sbin/sysctl net.inet.ipf.fr_udptimeout=600</earlyshellcmd>
<earlyshellcmd>/sbin/sysctl net.inet.ipf.fr_udpacktimeout=600</earlyshellcmd>
<earlyshellcmd>/sbin/ipf -E</earlyshellcmd>

Replace 600 by the desired value in seconds times two (i.e. 600 gives 5 minutes due to the way ipfilter measures the time).
