Possible to have Gateway and IP address in different network?

[nygenxny123]

i.e

dhcp is giving the host the follwing

10.11.12.23 255.255.252.0

Gateway is 10.11.12.1

However the IP configuration for

the switch that this is connected to is

10.1.12.51 255.255.252.0

gateway is 10.1.12.1

10.1.12.1 255.255.252.0

You will need a VLAN for the 10.11.12 network and trunk across the uplink to support the 2 subnets.

When a client wants to exchange data it looks at the source / destination IP and mask. If outside the mask it will forward to the default gateway no matter what it is. As long as the DG can be accessed

Hello Richard,

what you see can be normal:

it is different the second byte:

10.1

10.11

compare

sh run int fx/y of the port to which the PC is connected with

sh vlan

sh ip interface br | inc Vlan

the user port should be in a different Vlan of SVI interface Vlan

Edit:

they are in a different ip subnet but you can have multiple routers on a single ip subnet, one can be an HSRP VIP and one a physical IP address

Hope to help
