Hello ,sorry that iam a newbie in Linux so please answer to me in steps.THX

My problem is simple, iam runing ubuntu 8.04 (ebox 1.4) , i have installed and configured PPTPD server, i can connect and ping users perfectly. BUT i dont getting any gateway address, in my case i have to get IP address 172.16.0.1 (PPTP server address).

I tried to change localIP in pptpd.conf to 0.0.0.0 ,or my remote(ISP) address but nothing.

Can someone explain to me how can i manually assign gateway IP address to PPTPD Server ???

localIP in pptpd.conf is for setting the local ip that is going to be asigned to the end of the tunnel in the linux server,this means:

if you configure localip as 192.168.130.1 and remoteip as 192.168.130.2-31 when the client establish a connection to the server it will be as a ppp (modem) connection with two ends, one in the server with the address 192.168.130.1 and the other in the user with an assigned address from the pool configured (let's say 192.168.130.5); so setting this variable (localIP) as 0.0.0.0 is nonsense.

If what you want is to route the connections from your clients to the Internet, or an external network, try to use one of the options explained in "man pptpd.conf" under the common title: ROUTING CHECKLIST.
