Cisco 3750 Switch, vLAN No Internet, pfSense Firewall

mechanize
Level 1
Level 1

ISP Router:
WAN: to the Internet
LAN1Port: 192.168.200.1 >> Connected to pfSense WAN Port
pfSense WAN Port connected to Router LAN1Port 192.168.200.1
pfSense LAN Port Connected to Switch on Gi0/24

pfSennse has 3 vLANs
vLan1 Default 192.168.101.2 DHCP Range (192.168.101.100 - 192.168.101.200)
vLan2 HR 192.168.102.2 DHCP Range (192.168.102.100 - 192.168.102.200)
vLan3 Sales 192.168.103.2 DHCP Range (192.168.103.100 - 192.168.103.200)

Cisco C3750 switch has 3 vLANs

vLan1 Default 192.168.101.0 Gi0/1 Switchmode Access
vLan2 HR 192.168.102.0 Gi0/2 – 10 Switchmode Access
vLan3 Sales 192.168.103.0 Gi0/11 – 22 Switchmode Access

Gi/0/24 Switchmode Trunk

Internet working on vLAN1 Gi0/1 but not on any other port!
If I move ports from other vLANs to vLAN1 then internet works on those ports!

PCs on vLan2 and vLan3 are getting respective IP / DNS addresses (from pfSense DHCP) but not reaching to the Internet.

What should I do to enable the internet on other ports / vLANs on PCs connected to Cisco Switch?
Will appreciate any help / directions.
Thanks

You need dynamic NAT in ISP router If I am right. 
dynamic NAT include all prefix in pfsence.
