Hi All,

I am receving the below message in my router syslog.

%SSH-4-SSH2_UNEXPECTED_MSG: Unexpected message type has arrived. Terminating the connection from 112.25.233.178

while cross checking the ip 112.25.233.178 found out that is an China telecom Ip.

I am concerned that is someone is trying to hack my router?

How can i fix this issue?

Thank you.

Regards
