Hi
I've a RB411AH and upgraded it to v6.48.3 directly via Winbox, configured a PPTP server and DNS server and after that I can't access it.
tried many times and restarted it, when I got access to it, I've reset the configuration and ticked "no default configuration" but now I can't access it even when I connect my PC to it directly via RJ45.
How to fix it and what's latest firmware for RB411AH if 6.48.3 isn't supporting ?
