Firewall settings needed to support second life

[Oracle Neutron]

Are there any firewall settings needed to support second life?

Not normally, although some public agencies (schools, libraries, corporations) add firewall restrictions to keep users from using excessive amounts of bandwidth.  If that's the case, you may find that your access to SL -- a real bandwidth hog -- is blocked.  Depending on your level of authority, you may be able to get past the firewall yourself.  If not, you'll have to talk with the responsible folks in you IT area.  Read this to see what's involved >>> https://wiki.secondlife.com/wiki/Configuring_your_firewall  .  Oh, and this too >>> https://wiki.secondlife.com/wiki/How_do_I_configure_my_software_firewall_%28such_as_Norton_Internet_Security,_McAfee_Personal_Firewall,_or_ZoneAlarm%29

Besides your firewall, you may need to open some ports on your router. I had to manually set a few of those. Here's the list I have, several of these ports were not open in my default router configuration:
 
Port    Protocol    Used For
53    UDP and TCP    DNS lookup
80    TCP    Second Life web resources
443    TCP    Second Life web resources/client authentication
3478    UDP    Voice/STUN traffic
3479    UDP    Voice/STUN traffic
5060    UDP    Voice/SIP traffic
5062    UDP    Voice/SIP traffic
12000-29999    UDP    Voice/RTP traffic/Core protocol communication ** (see note below)
12043    UDP and TCP    Capabilities/map services/simulator communication
12046    TCP    Texture downloading
21002    TCP    Voice signaling

I had to add TCP 7060 to get audio streaming to work.
