Access Internet from Guest VLAN

Js.505050

Level 1

Hello, need help. I'm trying to allow Internet access from a newly created VLAN.

Network

Using C1760 router for Voice T1, currently Default Gateway for Voice and Data.C1760 is configured with 2 sub-interface networks 10.1.1.x & 10.100.1.x
Using ASA5510 for Security.
Using 2821 router for bonded Data T1's

Using Catalyst C3750-48p as Switch.

What I have configured...

A new sub-interface on C1760:

interface FastEthernet0/0.3

description Engineer VLAN 3

encapsulation dot1Q 3

ip address 192.0.0.1 255.255.255.224

ip helper-address 10.1.1.17 (this is a DHCP/DNS server on VLAN 1)

no snmp trap link-status

Configured switch ports FE 2/0/33 - 2/0/41:

interface FastEthernet2/0/33
description Engineer VLAN 3
switchport access vlan 3
switchport mode access

end

Configured Windows Server DHCP Scope:

Scope: 192.0.0.0, 255.255.255.224
IP Range: 192.0.0.2 - 192.0.0.29

DNS: 10.1.1.17 (VLAN 1 DHCP/DNS server)

Clients obtain an IP address in the 192 network from DHCP with 10.1.1.17 as DHCP/DNS server. I believe I need to configure routing for the 192 network, but I don't know where to do this.

Anyone interested, I resolved by issuing the route inside 192.0.0.0 255.255.255.224 10.1.1.x command in the ASA5510.

Also replaced Windows DHCP scope with C1760 scope.
