hello everybody, I have a cisco 1601 router in my office and windows Nt server in my home.For administration reasons i want to configure the router to call me back when i call him from home. I also have an isdn bri line and two net modes to make the project the scheme is: CISCO_1600 --NET MODENET MODE ----NT SERVER I ' ve tried to make a ppp multilink connection and it works fine .Then i configure the router to callback and i install the routing and remote access service in windows nt server with all (i thing) parameters configured well. I configure the nt server to call as a ras client , to receive calls as ras server , and to work for Dial on Demand Routing.Also I a make a user with all pap credentials right and with the permission grand dial in. When i place a call to the router with dialup networking and then in 3 seconds about cancel the try , the router calls me bac after 15-20 seconds, but i cannot ping to the router . As it seems in the debugs output the router sends pap request but the nt server does not answer,show the ppp phase doesn t came up and no ipcp messages are shown. has anyone idea where is the problem? Follw is the router configurations and the debugs output,appreciated any help! KOSTAS AGGELAKIS CISCO_1600#s ru Building configuration...
