Stun is normally used to solve nat problems with SIP (VoiP)
VoIP telephones use a stun server beside the regular proxy where the stun
server makes it possible that the SIP phone can be behind a firewall

Betreff: Re: [Shorewall-users] Two DMZ servers can't be access from
internetand can't ping internet IP address.
I just checked something again by tcpdump:
09:50:46.780780 IP 172.16.0.177.boinc-client > 124.40.51.145.nat-stun-port:
UDP, length 33
09:50:46.830262 IP 124.40.51.145.nat-stun-port > 172.16.0.177.boinc-client:
UDP, length 66
09:50:54.780885 IP 172.16.0.177.afrog > 96.17.157.44.nat-stun-port: UDP,
length 49
What is nat-stun-port?
Thanks !

It's Multicast. Not involved in your problem.
