I'm using UERANSIM v3.2.6 agains Open5GS on a kubernetes cluster. All is fine and the UE container has its uesimtun0 interface from which I can access to internet with ping -I, traceroute -i and curl --interface. However, I want to make use of nr-binder to make it able to use commands that don't allow specifying the source interface or source network address. When I use nr-binder with IP addresses which are connected to UPF N6 interface it works well but when I try with DNS names (e.g. www.google.com) it fails.
root@ueransim-ue-f9575f6dd-7n5xx:/ueransim/build# ./nr-binder 10.45.0.13 curl www.google.com
curl: (6) Could not resolve host: www.google.com
root@ueransim-ue-f9575f6dd-7n5xx:/ueransim/build# ./nr-binder 10.45.0.13 ping www.google.com
ping: www.google.com: Temporary failure in name resolution

Hello
I'm using UERANSIM v3.2.6 agains Open5GS on a kubernetes cluster. All is fine and the UE container has its uesimtun0 interface from which I can access to internet with
ping -I,traceroute -iandcurl --interface. However, I want to make use ofnr-binderto make it able to use commands that don't allow specifying the source interface or source network address. When I usenr-binderwith IP addresses which are connected to UPF N6 interface it works well but when I try with DNS names (e.g. www.google.com) it fails.Thanks in advance.
