switching wan's - from static ip to ppoe [help]

Hi all,

I'm struggling with the current situation:

I want to bypass my isp router/modem since I can connect directly to the fiber uplink with an ethernet cable. Pfsense was configured with a static ip behind my isp box.

I've successfully created a new interface which connect to my isp via ppoe, and set the default gateway to it. From pfsense (wan) I can ping a remote server, from the lan I cannot.

I'm guessing I forgot to specifying some routing rules somewhere, but I know where.

Thanks in advance,

If usefull here are my system spec:

System 	PC Engines APU2
Version 	2.4.5-RELEASE (amd64)
