One Wired, One Wireless setup

[eyesdrop27]

Hi to all,
I have two internet connections. I would like to ask, if it is possible for this setup

WAN(Wired)–>Pfsense-->WiFi(Another Internet Connection)-->AccessPoint-->Accespoint-->Switch

Can pfsense get the Ipaddress of the 2nd internet connection? Without another LAN Port?

Thank you for your response.
