3750 switch setup as a router

i  have a cisco WS-C3750X-48T-L  switch i need to enable routing. this is a fresh switch no config just need to get it to route to an ip.

switch gateway: 50.200.158.149 255.255.255.252

switch usable ip; 50.200.158.153 255.255.255.248

I need to set vlan 1 to 50.200.158.153 255.255.255.248 and have it route outside packets to

50.200.158.149 255.255.255.252.

this is a standard Comcast business setup but i am having a difficult time getting the switch to route outside packets.

If i put a host on the inside 50.200.158.154 and put it its gateway as 50.200.158.153 i need it to get to outside.

i basically need to set the switch as a router. so a genric config would be fine i can replace the ip's

conf t

ip routing

!

interface GigabitEthernet0/1

 no switchport

 ip address 50.200.158.150 255.255.255.252

 no shutdown

!

interface Vlan1

 ip address 50.200.158.153 255.255.255.248

 no shutdown

end

Plus maybe a static default route to 50.200.158.149?

Good call @TimotiSt

It won't work without that :-)

conf t

 ip WS-C3750X-48T-S   route 0.0.0.0 0.0.0.0 50.200.158.149

end
