In a attempt to allow ssh login only from specific remote networks, I added a remote (internet) address 62.x.x.x/255.255.255.255 with my SME servers LAN ip as router.
This didn't work as I hoped, so I deleted the entry again.
But now no traffic whatsoever from 62.x.x.x is working anymore, everything works fine from all other internet addresses, what went wrong?
