Hi together,
I’m struggeling a bit with my docker setup running in a Hetzner Cloud environment:
Home network
192.168.178.0/24
|
Fritzbox Router
192.168.178.1
|
Wireguard VPN
10.10.10.0/28
|
OpnSense firewall
10.100.0.2
|
Docker host
10.100.0.3
|
Docker ipvlan (l3)
10.100.1.0/24
|
Docker Containers
10.100.1.2 - 10
The goal is to run applications like pihole, node-red, etc. within this environment and access them through the mentioned Wireguard VPN tunnel from my home network. Other applications like vaultwarden should be published directly through the Opnsense firewall.
Generally I can reach all my containers from the home network as well as clients within the home network from my containers.
Strange things begin to happen if I spin up a new docker container.
After a new container is deployed some of the other containers stop responding to http-requests (pihole web-interface for instance), but all containers are still reachable by ping. The pihole container seems to be able to respond to DNS requests as well.
I can see the http-request from the client in the affected docker container logs as well, but the client does not get any response.
After 10-15 minutes the problem is healing itself and all containers are reachable by http again!
Containers are randomly affected by this problem after deploying a new container.
My guess is a problem with MTU size, because smaller packages like DNS and ICMP are working fine.
ip link output from the docker host (ens10 is parent interface for ipvlan L3 mentioned above):
2: ens10: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1450 qdisc fq_codel state UP mode DEFAULT group default qlen 1000

altname enp0s10
tcpdump output from the docker host (http is not working until 11:03:50.041785):
