Answer 1

You did not enable NAT. You need something like:

ip nat inside source list 1 interface GigabitEthernet0/0/0 overload
!
access-list 1 permit 10.1.10.0 0.0.0.255
access-list 1 permit 10.1.11.0 0.0.0.255
!

The above will determine and match the interesting traffic that you want to NAT.

Also, you never use the ip default-gateway command on a router with routing enabled. Cisco has a document that explains: Configuring a Gateway of Last Resort Using IP Commands:

The ip default-gateway command differs from the other two commands. It should only be used when ip routing is disabled on the Cisco router.

You can, and should, eliminate the ip default-gateway command if ip routing is enabled. This is a mistake that rookies often make.

As far as network 10.130.1.0/24 or any network outside that, the inside networks do not exist. The outside networks only see the router 10.130.1.254 address because all the inside addresses are translated to that address. The outside devices cannot ping the inside devices. You can forward specific TCP or UDP ports to specific inside addresses.
