DNS resolution question

Open kajtmzb opened this issue 5 years ago • 2 comments

Hi @aligungr, does nr-ue accepts DNS server information provided by SMF during PDU session establishment? I can see it on N2 interface as a part of PDU Session Resource Setup Request message sent by AMF. However, domain names cannot be resolved on a dedicated VM (Ubuntu) where nr-ue has been installed. Ping (using uesimtun0 as a gw interface) to any IP address works well. Thanks in advance for your answer!

Hi @kajtmzb Thanks for the question. Currently the UE does not handle received DNS address. Because usually DNS resolution is performed locally by the machine that nr-ue installed. For example for ping -I uesimtunX google.com command, name resolution for google.com cannot be performed by UE, instead ping tool itself performs a DN resolution.

Thanks, clear. I was just curious if I forgot or overlooked something in a config file ..
