To test a router, we need an upstream connection. In this directory, find
- chr.sh, a script that will start a RouterOS image in qemu. Login when prompted, username is "admin", blank password
- routeros.config, a set of commands you can feed into routeros to set up PPPoE
To get the chr-7.5.img image, visit https://mikrotik.com/download and look in the section titled "Cloud Hosted Router" for "Raw disk image"
You may need to open your firewall a bit to allow multicast packets so that the upstream and the liminix qemu instances may communicate
config.networking.firewall.extraCommands = '' ip46tables -A nixos-fw -m pkttype --pkt-type multicast -p udp --dport 1234:1236 -j nixos-fw-accept '';
To connect to the routeros serial
The Qemu instance running RouterOS is headless, but it creates two unix sockets for serial port and monitor.
