My network used to be one vlan (vlan1). All devices on the network to point to my PIX as the default gateway to the Internet. Since, I vlan-ed the network into multiple vlans using the ip routing feature on the 3550, I cannot access the Internet.
I basically follow the sample configuration found on the Cisco Document ID 41260 (Configuring InterVLAN Routing with Catalyst 3750/3560/3550 Series Switches) to setup the attached Cat 3550 configuration. The Pix configuration is my current one flat layer network configuration.
Please advice as to what I missed or did wrong that I cannot access the Internet with this setup. Thanks
>> The Pix configuration is my current one flat layer network configuration.
PIX configuration has to be updated to:
be able to route to the C3550 the new private IP subnets
be able to NAT for the new private IP subnets
looking at your current configuration we see:
nat (inside) 1 192.168.0.0 255.255.255.0 0 0
you need also:
nat (inside) 1 192.168.2.0 255.255.255.0 0 0
route inside 192.168.2.0 255.255.255.0 192.168.101.253
this for each new subnet like 192.168.20/24
Hope to help
