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): How do you set up a DHCP pool?
Finally, this post has information on setting up a T1 and assigning public IP addresses for Internet access (for reference): Re: Basic T1 Setup with AdTran Router
