DNS host mapping for tools that don't read the etc/hosts file

I have a local (192.168.0.xxx) machine that can be accessed over the local network via Putty (without Kerberos) and via MobaXterm. I added an alias for the target machine in the Windows etc/hosts file (which successfully facilitates pings to it by name) and added an entry for that machine in my router's DNS Host Mapping index (which had no effect on anything that I'm aware of).

3c58.com IS routable on the Internet, but the local machine: Level10.3c58.com is not. I'd like kerberos to create tickets for the local machine, but I'm out of ideas on how to get that to happen under present circumstances. Is there some way to convince Kerberos to look at the hosts file on windows or somehow tap the router's domain name server setting (I think they're being ignored at present).

Thanks

    Actually, ... it isn't smart to use the router's DNS Host Mapping index- doing so will mirror routes from the listed machine right back to it, thereby denying that machine access to the Internet. So, ... I have since removed that entry in the router's DNS Host Mapping page.

    Really just trying to find a way to remember login credentials to I don't have to type them every time that Putty times out. Thought a Kerberos ticket would do the trick, but setting that up is complicated and it seems to require a routable server on which to obtain/store the tickets. Anyone know how to get Kerberos work on a local network?

    Hello

    Thank you for your question and reaching out.

    You may need to define some NAT rules so that your router can forward traffic of Level10.3c58.com to your local computer ( 192.168.0. ),
    You may also change some public DNS settings or CNAME records so that you local computer (192.168.0.xxx) is reachable externally.

    Please also try to disable local Windows firewall and security software you may have which sometimes blocks traffic.
