Home proxy with content filtering

[Buffalo2102]

I run a home server based on proxmox hypervisor and would like to add a virtual machine/appliance for web content filtering, primarily for my daughter.

I'm looking for any suggestions for software (e.g. Squid, Dansguardian etc.), preferably free and open source.

• I mostly use Debian as my base OS but would consider other distros/Windows.

• I would prefer the proxy to be transparent.

• I would like to filter content and also prevent internet access based on time and device, if possible.

• Fairly simple to maintain, although I am a quick learner.

• Not too heavy on resources.

Grateful for any suggestions.

Thanks

Buff
