Hi All,

Having issues with CSF blocking everything on a local subnet DA web server. I have the effective ports open and I enable CSF and I lose connection to everything instantly. I have to go to console to disable it.

Also, I know about the SPI issue, I currently have it disabled and this still happens.

See attached console messages that happen when I enable. What other logs should I be checking?

Thoughts?

How do you manage to forward to a subnet? I've never seen this before. The destionation is always an ip addres, so an ip or localhost like 127.0.0.1 which is also an ip.
So to me this seems like a configuration failure because somewhere, something is pointing to 255.255.255.255.

255.255.255.255 is broadcast.... they are broadcast packets from other machines and CSF is blocking them.

I might just need to white list my local lan see if its only a local issue.

CSF shouldnt be blocking the local LAN though, very odd.

Also running DA on a local web server and forwarding ports from router to web server is fully supported.

you can add IP-range to allowed to CSF, or whole ethernet interface (this will also decrease CPU load to analyze traffic by CSF on it).
just open CSF conriguration - all passages described with details.
