<![CDATA[Open ports 25 and 110]]>Hi

I have the following situation:

I configured the pfsense as a transparant bridge.
My setup:
pc –------------------------------ pf ------------------- switch
192.168.2.x----192.168.2.249(lan) - pf - 192.168.2.251(wan) --- switch

I just want to create a firewall within the same network( later i want to use this with external ip's)

Now i was testing my firewall rules and came to some strange conclusions.

I have blocked all traffic on lan and wan (all ports, udp and tcp).
When i do a portscan from a pc connected to the switch to the pc behind pf, I notice port 25 and 110 are closed

That was the reason the ports were open.

Thx for the response.
this can be closed.

Your screenshots do not prove that.

The problem is that pfsense doesn't block those ports. :s
