Are you running a routing protocol between the 3550 an upstream router?

Does the upstream router have an entry in the routing table with a next hop if the 3550 for the new IP subnet?

I would issue a show ip route on all relevant devices and utilize ICMP Ping to very reach ability.

Hi jprada

I hope the following steps help out:

1. Make note of the vlans you need to route between

2. Use sh vlan to ensure the vlans are present

3. For the switch to be able to route between vlans IP addresses need to be assiged to both (all routed) VLANS

4. Since you have an ip for vlan1, I will just demonstrate how to set an ip for vlan2

(config)#configure terminal

interface vlan2

ip address 192.168.2.1 255.255.255.0

no shut

5. Configure the interface to the default router (the one facing your ISP thru which you say VLAN1 can access the internet)

interface fa0/1

no switchport

ip address 15.14.13.12 255.255.255.0

no shut

6. Configure a default route pointing to the internet

ip route 0.0.0.0 0.0.0.0 15.14.13.11

7. Dont forget to point your hosts to the VLAN ip as their default gateways.

Make sure to include the new subnet (vlan 2 network) in the nat pool.
