Línea de trabajo

Start by tracing the WSL DNS tunneling path that serves requests at 10.255.255.254 and compare it with the mirrored loopback path to 127.0.0.1. The report provides reproducible DNS query cases and diagnostic results, but does not name source files or tests, so first locate the tunneling implementation and its existing DNS tests. Done means tunneled queries return answers for the reported names and record types without timing out.

Docker Engine 29.8.2
Visual Studio Code 1.141.0 (user setup)

Repro Steps

On Windows, run a local DNS resolver bound to 127.0.0.1 and set it as the DNS server of the active adapter (here: Safing Portmaster, forwarding to Quad9 over DoT).
Configure %UserProfile%\.wslconfig with networkingMode=mirrored and dnsTunneling=true, keep the WSL-generated /etc/resolv.conf (nameserver 10.255.255.254), and run wsl --shutdown.
In the distro, query the tunnel and the Windows-side resolver for the same names:
- dig A archive.ubuntu.com @10.255.255.254 +time=3 +tries=1
- dig A archive.ubuntu.com @127.0.0.1 +time=3 +tries=1
- dig AAAA awscli.amazonaws.com @10.255.255.254 +time=3 +tries=1
- dig AAAA awscli.amazonaws.com @127.0.0.1 +time=3 +tries=1
Resolve the same names through glibc with the default configuration: curl -sI https://awscli.amazonaws.com and sudo apt update.
For comparison, resolve the same names on Windows: Resolve-DnsName archive.ubuntu.com -Type A -DnsOnly -NoHostsFile and Resolve-DnsName awscli.amazonaws.com -Type AAAA -DnsOnly -NoHostsFile.

Expected Behavior

The DNS tunnel at 10.255.255.254 returns the same answers as the Windows resolver, within a comparable time: A records for archive.ubuntu.com, and an empty NOERROR (NODATA) response for the AAAA query on awscli.amazonaws.com, which is a CNAME into a CloudFront distribution without IPv6. Tools that resolve through glibc (curl, ping, apt) complete normally, as they do on Windows and as they do inside WSL when /etc/resolv.conf points directly at 127.0.0.1.

Actual Behavior

The tunnel never replies to some queries, while the Windows resolver at 127.0.0.1 answers the same queries immediately:

dig A archive.ubuntu.com @10.255.255.254 fails with communications error to 10.255.255.254#53: timed out / no servers could be reached. The same query against 127.0.0.1 answers in under 300 ms.
dig AAAA awscli.amazonaws.com @10.255.255.254 never returns. The A query for the same name does resolve through the tunnel, and other names such as google.com resolve normally, so the failure depends on the name and the record type.
On Windows, Resolve-DnsName -DnsOnly -NoHostsFile resolves every affected name and record type without delay.

Inside the distro this breaks ordinary tools. curl https://awscli.amazonaws.com fails with curl: (28) Resolving timed out after 5000 milliseconds. ping awscli.amazonaws.com hangs before printing its PING header line. apt update stalls at Connecting to archive.ubuntu.com and Connecting to security.ubuntu.com. getent ahostsv4 awscli.amazonaws.com succeeds, because glibc with AI_ADDRCONFIG sends only the A query, which is misleading during diagnosis.

Connectivity is not affected. ICMP to the resolved CloudFront address succeeds, and curl --resolve awscli.amazonaws.com:443:<ip> completes the TCP connection, the full TLS 1.3 handshake and the HTTP request. Pausing Portmaster does not change the behaviour inside WSL.

Workarounds observed:

options no-aaaa in /etc/resolv.conf fixes awscli.amazonaws.com but not archive.ubuntu.com, so the bug is not limited to AAAA queries.
generateResolvConf = false with a static /etc/resolv.conf containing nameserver 127.0.0.1 fixes every affected name. The queries then reach the Windows resolver through mirrored loopback and return correct answers.
