Can't find gateway

I have just installed Redhat 7.7 on a Virtualbox.

I edited ifcfg-enp0s3 to add my network info:

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
name=enp0s3
UUID=xxxx
DEVICE=enp0s3
ONBOOT=yes
BROADCAST=x.x.x.255
IPADDR=x.x.x.198
NETMASK=255.255.255.0
GATEWAY=x.x.x.209

I then issued service network restart

I can ping my local device x.x.x.198, but I can not ping the gateway.

Any suggestions on how to proceed would be greatly appreciated.
