  • 1.  Using address Groups in Policy to deny unwanted traffic

    Posted 10-08-2015 09:11

    As I peruse through logs in my webservers/ftp/and other public facing boxes, I see constant attempted logins (don't we all).   About once a month, I have taken those handful of those addresses and add them to a group I called Intrusion Protection and Intrusion Protection 2.  I maxed out the first with 32 addresses so I moved on to another group.

    My problem is for some reason it doesn't like the groups and allows the traffic anyway.   Usually, I am not able to catch someone in the process of hacking, so I assumed it was working.

    Here is my (partial)config for the rule and groups.  Can anyone see why it wouldn't work?  If I add the single address as a rule, (even though it's a /24) it denies, but not in the group.  I've check to see if the rule was shadowed, but it is at the top.  Also, usually in the GUI under policy elements you would see "in use" if the element is in a rule and applied.  I don't see that.  Hopefully it's something dumb I'm missing.  thanks in advance.

    Posted 10-08-2015 09:29

    Do you happen to have any kind of inbound NAT (MIP/VIP) you are using?  If so, you would need to configure the policy from those groups to the MIP address.

    The public facing devices are MIPs.  But wouldn't the "any" cover those?  or do I have to create a "group" with the MIPs and reference them that way?

    You would need to specify the MIP address in a policy.  MIP policies are global policies, which is why the traffic is failing to use the zone to zone policy.

    Posted 10-08-2015 13:04

    I was concentrating on why the source addresses wouldn't take.  I just read about what you said.   Although I can't get the MIPs in a group, I have the "suspect" ips group. 

    Just a thought though ....Is there an easier way to go about what I am doing?



  • 6.  RE: Using address Groups in Policy to deny unwanted traffic

    Posted 10-08-2015 13:08

    You could create a negate MIP policy.  It would pretty much state "any except these."

     thanks for the help.
