Should I replace my linksys router/firewall with a different firewall since I am changing from rr to a T1 connection?
I work with small businesses and one of my client's is dumping rr and getting a T1 for his phone system and internet connectivity. The vender will install an adtran device and part of the T1 will be split off for the phones leaving the rest for the internet. I am told that this adtran is also a router. My firewall, which is currently the linksys router/firewall, would attach to the adtran. Will this even work with linksys? Should I replace the linksys with something like a PIX? What are the pros and cons? The new vender told me that my client would be getting 4 public ip addresses. What sould I do with these extra ips? The linksys is only using 1 public ip and PAT for internet connectivity. I work with rr and dsl. This is my first T1 so please keep this in mind when responding to my question.
