UPD packets

[wyman]

All, I am on Windows 7, HP PC.... cable modem..

I keep getting messages on my Norton AV that read, "Inbound UDP Packet Allowed". I traced the ISP these packets are coming from... and it is my ISP.VIA port 53. I see that one of the ISPs, however, is in another state on the other side of the country, and its to another port. i believe 8085??

Are these causes for alarm?

 

[not so gray matter]

Capture some of the packets, upload them and someone should know.

Wireshark Go deep.

Probably not, UDP is not the most dangerous protocol. But if there are 2 ISP's one yours one not, the other one (and port ) should be blocked.

Thanks... I guess what I meant was that 1 of the ISPs is my actual ISP company, not me.

I guess what Im wondering is...

Why is my ISP company sending me UDP packets?

For my opinion, UDP packet, User Datagram Protocol, usually, used to stream media, like playing videos. For your case, on port 53, mostly is from the Domain Name System, which is called DNS in short. well, correct me if i am wrong. If you would like to check for the exact IP and trace the source, go to cmd and type netstat -n to see what are your listening port and established ports, then this port is connecting from where. Hope that helps.

This guy is correct. UDP is connectionless. You are requesting the packets whenever your computer tries to resolve a domain name to an IP address. Turn those Norton alerts off. They're bogus.
