Network routing problem to intranet servers on VPN

[rcsilva83]

Actual Behavior

After starting Rancher Desktop, my WSL distros get Destination Host Unreachable error when pinging to intranet servers. As a result, I also can't use my corporate Docker registry with Rancher Desktop.

Steps to Reproduce

1. Close Rancher Desktop and run wsl --shutdown to ensure a clean environment
2. Enter Ubuntu WSL distribution and run ping corporate.docker.repo with success:

ping docker.corporate.docker.repo
PING server.name (172.17.204.106) 56(84) bytes of data.
64 bytes from server.name (172.17.204.106): icmp_seq=1 ttl=61 time=34.7 ms

3. Start Rancher Desktop
4. Run again ping corporate.docker.repo inside Ubuntu WSL distribution with error.

Result

ping corporate.docker.repo
PING server.name (172.17.204.106) 56(84) bytes of data.
From 172.17.0.1 (172.17.0.1) icmp_seq=1 Destination Host Unreachable

Expected Behavior

ping docker.corporate.docker.repo
PING server.name (172.17.204.106) 56(84) bytes of data.
64 bytes from server.name (172.17.204.106): icmp_seq=1 ttl=61 time=34.7 ms

@rcsilva83 can you please try enabling experimental host resolver and let us know if it fixes the issue.

Thanks

[rcsilva83]

@Nino-K it didn't work.

[ripun]

seems similar issue #2477

[rcsilva83]

Yes, @ripun . Indeed it seems to be a similar issue with different VPN software.

[ripun]

I hope issue gets resolved sooner , because this is kind of blocker for windows user with VPN to access private docker registries (docker pull/push/login are must)

[Nino-K]

@rcsilva83 a few questions:

1. Did you fully restart the rancher desktop after setting the "experimentalHostResolver":true?
2. What kind of VPN software are you using?

Thanks,

@Nino-K

• Did you fully restart the rancher desktop after setting the "experimentalHostResolver":true?

Yes, I did

• What kind of VPN software are you using?

Microsoft Always On VPN

[rcsilva83]

Just a hint: Podman with podman machine works well. Maybe you can see how it's done there.

[Nino-K]

@rcsilva83 please use our latest release 1.9 which includes a solution for when using Rancher Desktop behind a VPN. You can enable it using:

rdctl set --experimental.virtual-machine.networking-tunnel=true

I'm going to close this issue, feel free to re-open it if the issue still persists.
