Networking noob here, currently trying to troubleshoot BTH VPN. Packets get to the router find, I can connect to the web console over the VPN, cannot ping or otherwise connect to other VPN clients, LAN devices, or the internet. And traceroute shows as much, all packets besides those with the router as it’s destination seem to get dropped.
Is there any way to sort of follow a packet through routeros? Have it tell me exactly when and why the router decides to drop a packet? Whether that’s because of a firewall rule, because it’s unrouteable, or whatever else?
EDIT: After monitoring the wireguard interface set up by BTH, it seems the packets are not being dropped, but seem to be errors. Been spending a few hours on the problem and I’m really scratching my head as to what the problem is, can’t find anything that explains why the packets are errors.
EDIT 2: Also heres my config, if anybody could spot the issue I’d be very grateful 
, but would also like to know the answer to my above question so I can better troubleshoot in the future.
