Do I need to set routing for IP address of IP Pool?

Hi guys,

I want to know about IP Pool if I use IP address besides Interface IP address.

 

I set IP address as 192.168.1.254 on wan1.

and set NAT internal → wan1 to use IP Pool (192.168.1.1 - 192.168.1.10).

wan1 is conecting on Catalyst 3560X.

and Catalyst 3560X is conecting Internet.

 

Do i have to set routing for SNAT IP Pool address(192.168.1.1 - 192.168.1.10) on Cat 3560X in this case ?

 

 

Thanks in advance.

If the subnet is /24 or larger and the switch has one of IPs in the subnet, it would deliver the packets destined to those IPs through the interface.

Thank you for your reply Toshi-San I understand that. If I set IP pool 10.10.10.1-10.10.10.10 so I need routing for this IP Pool on 3560X in this case?

Yes. Otherwise the switch (acting as a router) doesn't know where to deliver the packets destined to 10.10.10.x.
