Basic configuration question

[shane]

I have just set up a 3430 with a T1 circuit. What I am trying to accomplish is just a simple setup that would be like if I were just setting up a small in home router with cable or DSL. I am trying to figure out how to just use DHCP with a private default gateway such as 10.0.0.1 or 192.168.1.1. The router would be connected to a 24 port switch and the clients would just pull DHCP. Can anyone help this newbie accomplish this?

To elaborate a little further. I have the HDLC configured and have internet access to my test pc when plugged directly into the Eth 0/1 port. I had to statically configure the computer with one of the public IPs off of the LAN IP Block. The default gateway on the Eth 0/1 interface is also set to the first usable IP on the LAN block provided by the ISP. I am trying to figure out how to change the default gateway to a generic 192.168.x.x and use DHCP down to any clients that will be behind the switch.

Thank you for asking this question on the support community.  It sounds like you are only missing a few steps.  If you have the T1 configured and routing setup already (as it appears you do), then you will need to configure the LAN IP address, firewall (for NAT) and DHCP.  All of these steps are covered below.

The Configuring Internet Access (Many to One NAT) with the Firewall Wizard video walks you through how to setup the firewall for NAT and Internet access.  Furthermore, the Configuring T1 and E1 Internet Access in AOS has detailed information on setting up the T1, firewall, and IP addressing in written form. 

Here is a post on how to setup DHCP (it also links the DHCP guide): 

Finally, this post has information on setting up a T1 and assigning public IP addresses for Internet access (for reference): 

I hope that makes sense, but please do not hesitate to reply to this post with any additional questions.  I will be happy to help in any way I can.
