How to allow traffic from WIFI to LAN

[lvvloten]

Hi group,

I can't seem to figure this out: How do I need to configure the firewall to allow access from my WIFI network to a specific host/port in the LAN network?

I am running pfSense in a VM on CentOS 7. In my setup I am using 3 network interfaces: WAN, LAN and WIFI. WIFI is in fact a wired network between my virtual host and my WIFI router. I am using pfSense for DHCP and DNS in my Wifi network.

Now I would like to allow access from any client in my Wifi network to a specific host:port on my LAN. But I can't get it to work.
I have defined rules both on the WIFI interface and on the LAN interface, with logging. But when I test the connections no traffic is logged.
I can capture incoming packages on my wireless interface, it shows lots of "[TCP Retransmission]" messages but never  reply.
The traffic seems to reach a dead end somewhere but I don't know how to solve it.

I would appreciate advice on how I can configure the firewall to allow this traffic?

Thanks!
Regards,
Lucas

For connections from Wi-Fi to LAN, the rules need to go on your Wi-Fi interface. Post your Wi-Fi interface rules.

Had you told us precisely what you wanted to pass I would have told you precisely the rule you need.
