OpenBSD with PlusNet VDSL
For a long time we’ve had a Cisco 887VA acting as our VDSL modem and gateway. We got this for the old flat when we moved in there in 2016 and took it with us to where we live now. It’s been quite reliable but the Ethernet interfaces are only 10/100Mbps and there are some limitations to the software where either features are hidden behind additional licenses or they are missing altogether.
