MaZeC Posted March 26, 2021 Share Posted March 26, 2021 Hello everyone, I recently recognized that none of my Dockers within a special Network have connection to the Internet, but I can access them through their IP-Adress (Web-Interface, Ping, etc.). I can ensure that the Router-Firewall is not the problem, because virtual machines and dedicated hosts have no problem connecting to the network or the Internet. My Docker Containers have a Static IP-Adress on a VLAN I passed to Unraid. Unraid Network Config: eth0: LAN: 10.1.0.0/16, Gateway: 10.1.0.1, Unraid-Server: 10.1.4.1 eth0: VLAN69: 10.10.0.1/24, Gateway: 10.10.0.1, Unraid-Server: 10.10.0.9 All Dockers related to this Problem have addresses in the VLAN69 Network For example: Speedtest-Tracker: 10.10.0.40 jellyfin: 10.10.0.17 The Problem: Speedtest-Tracker can ping jellyfin and vice versa, but neither can ping the gateway, the Unraid-Server or have internet access. The Gateway can Ping both. Everything worked fine till I recently recognized the Issue. Here you can see my routing table: I am glad for any idea what can cause this problem, or ideas how to further investigate this. MaZe Quote Link to comment
Vince_02 Posted August 12, 2022 Share Posted August 12, 2022 Hi ! I got a similar issue, but with 2 NIC connected, no VLAN, and both had their default gateway filled so 2 default route. I've only removed the Default Gateway on the 2nd nic (no internet on that one), restarted all Docker, all of them got internet connexion back. On your side, I think you are using VLAN. Are you sure that the network 10.10.0.0/24 or 10.1.0.0/16 can reach internet ? Hope it's help a little bit your issue... KR, Quote Link to comment
