<< protocol=6 rule=-1 >>?

Hello, all.

I am trying to decipher the following three lines from recent router logs of mine:

Thu Aug 31 10:31:35 2006 Unallowed access from 210.13.41.1:7799 to

192.168.1.151:22 protocol=6 rule=-1 Sun Sep 03 07:32:17 2006 Unallowed access from 88.116.151.228:35273 to 192.168.1.151:22 protocol=6 rule=-1 Sun Sep 03 07:32:20 2006 Unallowed access from 88.116.151.228:35273 to 192.168.1.151:22 protocol=6 rule=-1

Do these lines mean someone was able to get through my router on Port 22, or not?

Also, any idea what "protocol=6 rule=-1" means?

Thank you.
