Hello. I am still learning the whole thing of routing and all. I have a T1 terminating at an Adtran NetVanta router/CSU/DSU unit. I orignially configured it and has been working great since. The problem comes in that I cannot access a server that is being hosted by our parent company at their NOC. I can access it from anywhere else except my network. Was on the phone with the ISP and they said it was because I was routing through my serial address and not my lan block. Not sure but I would like to test it and see if they are correct. How do I implement this? can anybody help me?
