I have a RB450 connected to a powerbridge M5 via the WAN port.
the microtik was defaulted, using latest version, via quickstart I added public IP to wan, local IP to LAN and turned on DHCP, set new password Nothing else.
I can ping it (has a static public ip)
I cannot connect via web or winbox.
Any clue what it might be?
Are you trying connect to WAN?
The default configuration has firewall in WAN (usually Ether1 port)
In IP - Firewall - Filter Rules
you have to open (Action: accept) Dst. Port: 8291 (Protocol: tcp) for winbox and/or tcp port 80 for webfig in order to access the RB from WAN (Chain: input)
Those rules must be before the drop rule (in input Chain) in firewall for WAN port.
Don’t forget to put a password on the RB if you haven’t already.
