Creating vlans with public ips on 3750G

[kobina]

Hello,

Please I'm creating 3 vlans, one private ip addresses and the two for two blocks of public ips. After creating them devices on the same network are able to talk to each other on the private IP but not on the public ips. Any help why it is so?

Did you turn on ip routing on the switch. By default these devices run layer 2
