Block IP address

Block IP address

(OP)
I have a client who is getting a potential DOS. It is only coming from 1 IP. I am not yet fully familiar with the Netscreen 5GT. how to i block 1 IP from being able to communicate to any ports at the Netscreen.

RE: Block IP address

I am still learning to program an SSG20, so I don't know for sure, but I will give you some clues, since I have been reading the manuals for OS 6.1.0. First, identify the software version on your box. Then, download the manuals from Juniper's website. The chapter will have a title something like: "Attack Detection & Defense Mechanisms". Part of the configuration uses the "Screen" option, unless Juniper changed the names and syntax in later versions.

Happy reading!
