My router shows UDP packets from hosts that may be related to VoIOo's service, such as softlayer.com.
Here's some examples that show that a lot of UDP junk is being tossed here. Are these VoIPo related? I recall being told that some VoIPo systems toss out packets to overcome flaws (NAT related?) in certain routers.
Looking at the port numbers, below, supports the proposition that these are VoIP related (phone not in use).
Can I (we?) avoid having this? It fills up logs with junk, though the packet rate isn't large, it isn't a normal etiquette on the Internet.
My VoIP works (ATA on LAN side of router) and I have no port-forwards on 5060 et al. I think that popular consumer routers bridge incoming UDP packets back to the LAN side based on recent outbound UDP traffic.
So what's the deal with these UDPs arriving every few seconds?
