I *used* to have a script that added an additional routing table entry "for UPNP multicast routing":
#route add -net 18.104.22.168 netmask 240.0.0.0 dev eth0
My understanding was that this was needed for the Twonky server to remain visible to the control points on my network, however, I noticed that I've not had this in place for a few days, and I've not noticed any probems.
Is it just superstition that my NAS (which only hosts SMB shares and Twonky) should have this route, or is there an advantage that I haven't spotted yet?
My route table without this explicit entry for Multicast looks like this:
Code: Select all
Destination Gateway Genmask Flags Metric Ref Use Iface default bbhub 0.0.0.0 UG 0 0 0 eth0 127.0.0.0 * 255.0.0.0 U 0 0 0 lo 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
