Firewall Configuration

The Arc device uses MongoDB Device Sync to sync with its remote data and Memfault to perform Over The Air updates. It also uses The Almer backend to dynamically pull required apps.

The following network configurations need to be whitelisted to allow the Arc device to function properly.

Host	Protocol	Port
chunks.memfault.com	TCP	443
device.memfault.com	TCP	443
files.memfault.com	TCP	443
ingress.memfault.com	TCP	443
ota-cdn.memfault.com	TCP	443
memfault-prod-east1.s3.amazonaws.com	TCP	443
*.services.cloud.mongodb.com	TCP	443
api.almer.com	TCP	443
