Automatic outgoing NAT not working an hour after a reboot

[brenno]

Strange problem. A small description of my setup:

• PfSense 2.2.6 running on as VPS with multiple vlans
• One WAN connection
• 5 internal networks, 5 /29 subnetworks in 10.x.x.0/24 network
• One IPsec connection to one of our suppliers
• A few port forwards to an internal webserver (ports 80 & 443)
• Outgoing NAT configured as automatic. All internal networks are translated to WAN IP address.
• Sucicata is installed, enabled on the WAN interface but it doesn't look like it is dropping traffic

When I reboot the firewall outgoing NAT works but after about an hour it suddenly stops.

Case closed. Suricate was the cause of all the problems we had.
I've added the IP addresses that were not NAT-ed to the pass list and it worked.

Topic can be closed.
