Apologies for what's probably a noob question but I have tried researching I promise!



I don't get why some of these packets are getting through and others aren't. The floating rule that seems to be not-quite working is as follows:

Action Pass
Interface LAN, WAN [*I'll limit this when it's working]
Direction in
TCP/IP Version IPv4
Protocol any
Source Single host or Network 192.168.1.1/24
Destination Single host or Network 192.168.2.3/32
Destination port range any
Gateway 192.168.1.4 *[Route set up and seemingly working]
Advanced Options [all default]
State Type keep state


Notably the disallowed packets have tcpflags R, A or FPA, allowed packets seem to be S. I don't have anything set in the TCP flags section.

Why do you use a floating rule?
Can you please explain your setup and network more.
Please make some screenshots of the rules.

Apologies for the delay in replying!

I think I might have fixed it by moving to LAN rules and then turning off state detection in advanced settings.
