PfSense problem with NIC or missconfiguration

[demian]

Hi everyone, I installed a pfsense as a border router-firewall, with 3 NICs, WAN , LAN, other LAN
I installed some packages like squid, snort, pfblocker an dsomes filter rules

Everything works fine until without any reason LAN`s NIC stop working, it does not goes down, its still appearing connected(green) but no traffic can pass through. I realize this because I have a gateway monitor on that LAN that when this happen it turns "OFFLINE".

In logs there nothing about it. I already change the NIC but nothing, the problem occurs again.

I dont know if it is a harware problem o maybe a misconfiguration that cause a loop on tha t NIC

I need your help with this. here are all the filter rules

thanks
