There is a couple things you can check. Th 2 IP addresses are in a different subnets with the default subnet mask of 255.255.255.0. If you are using a router, you should have a file /etc/defaultrouter that has the IP address of the router.

If you are not using a router, you need to check your netmask. You would need a netmask of 255.255.240.0 for this to work. I also question the IP address 10.105.0.2. This IP Address is invalid.

I think that you have a problem with you netmask declared

e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 10.105.10.14 netmask ffffc000 broadcast 10.105.63.255
ether 0:21:28:14:69:84

netmask 255.255.192.0 ( ff ff c0 00)

Host 10.105.10.14 is not in same network with the gateway
10.105.0.2

The hosts most have 6 bits of resolution
0-63
