We are upgrading our multi-site network, and connecting two sites via a Bellsouth P2P T1. I have purchased 2 1721's with CSU / DSU. Site A will have the internet access with a PIX 515E firewall connected to our corporate concentrator. Site B will ONLY connect to the Internet Via Site A. Not sure where to start. I think I can configure, but any doc's someone may have would be helpful. I am curious if I need to setup any special Access lists, or how I configure site b to connect to Site A's Internet access???
