Subnetting help on ASA 5505

[sai cheng]

Hi,

we currently use the ASA 5505 router. We would like to create another subnet inside our LAN because we are running out of IP addresses.

current subnet info:

subnet:10.1.1.X

submark: 255.255.255.0

gateway: 10.1.1.251

we want to make another subnet, which we plan to use for all our network printers for now( other use in the future)

PCs at 10.1.1.X will be able to print on the new subnet.

the new subnet will be able to connect to the internet.

What's the best options we can do for the subneting?

how can we configure the router?

is possible to set another DHCP on the new subnet. we currently have one DHCP on the 10.1.1.X

Thanks!

You can create another VLAN on ASA 5505 for printers and assign an interface to that VLAN.

///////ASA 5505 Start  //////

conf t

int vlan2

ip address 10.1.2.251 255.255.255.0

int eth 0/2

switchport access vlan2

//////ASA 5505 End ////

//// Core switch Start/////

Have your core switch ports connecting to the printers assigned to Vlan 2

Creat a VLAN and IP helper address on the switch:

interface VLAN2

ip helper-address 10.1.1.x

///// Core switch END ????
