Well, the problem is that we have adquired a new server with Windows Server 2003 in order to replace an old unix server which has been functioning as file server and router for our office within the company. As a first step I'd like to configure the new server as router so I got the current IP configuration from the unix server and I configure the two nic´s in the new one with the same numbers, that is:
NIC 1 for LAN A (which goes to other network segment of the company):
NIC 2 for LAN B (which is for our network segment in the office):
Also all PC's in the office have as default gateway the IP 10.12.6.193. So apparently I have the same IP configuration in the new server and I have enabled Routing and Remote Access Service following the wizard selecting "LAN routing" in the first screen and then I select "LAN routing only" in the General tab within the properties option in the server name; so from the server I can ping every computer on both sides without problem, I mean LAN A and LAN B, but from clients in my office I can ping only to 10.12.6.193, 10.12.1.9 and 10.12.1.1 but that´s all, I cannot go beyond this.
What do I need to do??? please help!
And sorry for my english but I haven´t practiced for a long time :)
