In addition to @RonMaupin's answer: if the defined gateway is unreachable (and even not configured on the network) there's no way that command can be relevant anymore. It can't be used, so it can safely be removed.

A router that is configured to route does not use the ip default-gateway. It uses the default route, and you have that in the configuration. Cisco has a document that explains the differences: 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 ...

The RFC 1918 IP address ranges are marked as private, meaning they can't and mustn't be used on the open Internet. What you do with those addresses within your (private) network is entirely up to you. A proxy doesn't have an inherent logic to decide whether it's required or not. Actually, it's the source node ("client") that decides whether to use ...

The 192.168.0.0/16 range is a Private IPv4 address range as defined by RFC 1918, Address Allocation for Private Internets, but that does not mean it is defined as "internal." It means that the ISPs have agreed to not route packets with those addresses on the public Internet, but that does not mean that IPv4 distinguishes Private addresses from any ...

DHCP is assigning IP's with no issues. All switches are working with default settings, i haven't ran into any issues with the switches. I am teaching myself about VLAN's trying to learn if VLAN's ...

If the host is a router (a router is a host), then this perfectly normal, and the router will hapilly forward the packet according to its routing table (dropping it if it has no route for the destination) otherwise the host will simply drop the packet. Note that all modern operating systems also have routing capabilities and the packet may be passed on a ...

If router is deployed as perimeter devices in setup then static nat configuration has to be done on router and access-list is configured to control inbound and outbound traffic . If access-list is configured then port 80 ...

Routers route IP packets based on the IP address, and they have no clue about the transport protocol (TCP, UDP, etc.) or the transport addresses (ports). You seem to be concerned with the NAPT variant of NAT, which is something completely different, even though a router or firewall is the normally convenient place to run the NAPT. Routers will route packets ...
