Mikrotik help, anyone?

Unit is more likely bust then . Id say the switch chip is gone.

Oh and you may want to review your firewall rules and/or make sure you have a strong password

You may want to add the following firewall rules to blacklist the SSH attack ip address

/ip firewall filter

add chain=input protocol=tcp dst-port=22 src-address-list=ssh_blacklist action=drop comment="drop ssh brute forcers" disabled=no
add chain=input protocol=tcp dst-port=22 connection-state=new src-address-list=ssh_stage3 action=add-src-to-address-list address-list=ssh_blacklist address-list-timeout=10d comment="" disabled=no
add chain=input protocol=tcp dst-port=22 connection-state=new src-address-list=ssh_stage2 action=add-src-to-address-list address-list=ssh_stage3 address-list-timeout=1m comment="" disabled=no
add chain=input protocol=tcp dst-port=22 connection-state=new src-address-list=ssh_stage1 action=add-src-to-address-list address-list=ssh_stage2 address-list-timeout=1m comment="" disabled=no
add chain=input protocol=tcp dst-port=22 connection-state=new action=add-src-to-address-list address-list=ssh_stage1 address-list-timeout=1m comment="" disabled=no

I will sort the security out once I have the unit working... but thanks for the tips.

Really strange issue, hope you get your replacement sorted.

Thanks. Awaiting replies from mikrotik and the supplier...

Just resist the urge to throw it against the wall - It won't help with your warranty claim from the supplier

Update: faulty unit was replaced, new one working like a charm

Good to hear Sinbad.
