How do I filter out an IP address from connecting to my router & radio ssh port?

Looking at my ubiquiti airos log file of my rooftop wifi wisp radio, I see someone constantly trying to log into the ssh port of my static IP address.I can log into my radio and view the log file to see the login attempts:$ ssh -l admin radio_ip_address# tail -f /var/log/messagesDec 10 08:39:07 dropbear[2818]: login attempt for nonexistent user from::ffff:59.53.94.9:35088 Dec 11 12:18:43 dropbear[3304]: login attempt for nonexistent user from::ffff:59.53.94.9:42011 Dec 12 16:33:24 dropbear[5512]: login attempt for nonexistent user from::ffff:59.53.94.9:24119 Dec 13 22:40:12 dropbear[7789]: login attempt for nonexistent user from::ffff:59.53.94.9:22078 I can't change the ssh port because the wisp requires port 22 for air controlsoftware.I'm not too worried about the attack per se, but I'd sure like to simply sendthat IP address away.I tried setting a firewall static route to 0.0.0.0 but airos insists onrequiring a gateway IP address:Dec 15 06:26:32 route: add ip 59.53.94.9, netmask 255.255.255.255, gw 0.0.0.0,FAIL [error: 12]Airos won't accept 0.0.0.0 or null as a gateway IP address.Q: Is there a clever way to send a specific IP address into oblivion?

::ffff:59.53.94.9:35088

::ffff:59.53.94.9:42011

::ffff:59.53.94.9:24119

::ffff:59.53.94.9:22078

that IP address away.

requiring a gateway IP address:

FAIL [error: 12]

Yep, Just use this simple three step plan.

Purchase an assault rifle such as an AK-47.
Find the intruder.
Blast his or her brains out.

Problem solved. That's why we have guns! A gun is a terrible thing to waste!!!!
