I have some programs that require connections from localhost to localhost. And I don’t want to create a specific rule for each application, so I tried setting a global rule to allow loopback access.
The rule says
Allow TCP/UDP in/out from [loopback zone] to [loopback zone] if source port is any and remote port is any.
[loopback zone] is a predifined zone 127.0.0.1/255.0.0.0
But I still get a warning if any local application tries to connect to 127.0.0.1
I remebered once having had a similar problem, where the local application had my LAN IP as source ip. So I added another global rule that allowed all connections from 192.168.1.9 to [loopback zone].
Still not working…
