That advice is only relevant if a nat or stateful firewall is in use and 
the change must be made on whatever machine runs the nat or stateful 

These parameters are now tunable using sysctl, but only after the 
ip_conntrack module is loaded.

Be sure and change both parameters (the second is used once a reply is 
received, at least in 2.6.8).

net.ipv4.netfilter.ip_conntrack_udp_timeout = 30
net.ipv4.netfilter.ip_conntrack_udp_timeout_stream = 180
