two networks

Hi Guys, Brazilian Novice here in the area.

Good afternoon guys, I’m having a problem here, I have a cabling inside a company that owns some hubs so I can not delegate to each RB port a configuration. I would like to know if there is a way to make a network of fixed ip (company) and a dynamic network (clients) with hotspot to fixed (company) I would put in the queues and the dynamics (clients) I would put in the hotspot

Network in ( internet ) ( DHCP-Client )

Network out fixed ( 192.168.1.1/24 )

Network out Hotspot ( 172.35.69.254/24 )

Help-me Please…
Tank you guys

if you explain your question more will be easy to answer you
