HP Switch how to configure Uplink port

[knightsguard]

Hi,

New to working with switches. We have 3 VLAN's. Devices on VLAN 1 get DHCP IP and have internet access. Devices on VLAN2 have static IP and internet access. 

But devices on VLAN10 do not get DHCP or internet access even with a static IP. 

Port 48 is the uplink to a MX64 Firewall. Does this port need to be trunk or should the correct config work.

vlan 1
name "DEFAULT_VLAN"
no untagged 1-11,14,16-18
untagged 12-13,15,19-47,49-52
tagged 48
ip address 10.87.1.251 255.255.255.0
exit
vlan 2
name "POS"
untagged 1-11,14,16
tagged 48
no ip address
exit
vlan 10
name "ATMs"
untagged 17-18
tagged 48
no ip address
exit

Where is the default gateway IP address for the VLAN10 clients?
