Hello everyone!
I have a Juniper SRX firewall and in recent times I did had issues because
one or other user doing an attack outside. Usually it is compromised client
machines which create a lot of firewall sessions in outside direction.
I was thinking of two specific things as fix for this:
1. Can I somehow put a cap per security policy so that all available
sessions aren't chewed by clients?
2. We have very few clients who actually use firewall in outbound, rest
all in inbound. This I wish to skip firewall in outbound but in my test I
found it behaves strange. I tried with machine having inbound traffic via
firewall. They ping and port 80 also worked but SSH just hung up as soon as
I started. I see SRX can be used in unidirectional setup but somehow it
fails in my case.
Any suggestions/advice/ sample configs?
Thanks in advance!
