Add possibility of specifying the gateway address

[Guilospanck]

Description

When connected to a VPN that has the same Gateway (192.168.5.2) as colima/lima, I couldn't reach out to services in the other side from inside the container. Guess is the conflict of addresses.

• VPN has the same gateway address as colima (192.168.5.2);
• Tries to pull docker image from private registry only accessible via the VPN, which needs to pass through the gateway;
• Not possible.

P.S.: I have made some changes here and passing a different GW fixed my problem when using this version, still not sure if this is even needed. If it is, glad to contribute.

Hi, thanks for taking a dig at working around the issue.

Your solution is actually accurate (or at least close enough). I am a bit occupied at the moment and would have another look soon :)
