Accessing subnets via switch

Hello everyone,

I'm facing issues connecting to specific subnets via an ethernet connection to a switch.

Say the switch give access to 10.128.77.224/27

When I connect to any port that's working i get an ip address of 10.0.0.128 in the subnet 10.0.0.0/24

And no matter what I do I can't reach the initial subnet. I tried setting a static ip address in the initial subnet, adding routes to the initial subnet via the gateway 10.0.0.1 in 10.0.0.0/24 but to no avail.

Any ideas how to proceed ?

I do not have access to the switch administration, I'm doing all of this from a Linux machine. The goal is to access the subnet for testing purposes.

Thanks !
