I have some pieces of software that use "loopback" but not really traditional loopback. They us the "real" IP address of the computer instead of localhost or 127.0.0.1 I wonder if there is a way to set loopback to include IP addresses assigned to the host. I can't change the way a vendors software works.
I am not sure how to address this with centralized rules other than saying 192.168.10.10 can talk to 192.168.10.10 but I have dozens that need to talk to themselves and I am not too psyched to add all those rules.
Any ideas on what to do?
Ah. I see. The rule only really needs the remote set to "Any Local IP" right? No need to specify a local address, right since the value is relative to the local machine?
Allow any traffic where the remote address is [local].
It depends on what blocked network traffic you're seeing in the log. You have to make sure you write the firewall rule correctly according to how the traffic is being blocked.
Ah, yes of course you're right, thanks.
We pretty much allow all outbound here, so I never think of the sending side of the traffic.
