You can now open a router's own web interface (Webfig) straight from Centipid, without putting it on the internet.
On the Routers list, every router has a Web button in its own column, next to the Winbox port. On a router's page, Connection & RADIUS has a Web console row. Either opens the router in a new tab, over the same private tunnel Centipid already uses to manage it.
The link that opens it is single-use and lasts two minutes. Once you are in, the console stays open while you are working and closes itself after 30 minutes of no activity.
If a router's web interface has been switched off, the same card now has a Web service switch to turn it back on — and the Winbox column now shows just the port, since the address in front of it was the same on every router.
