Am I correct in assuming (and I am asking for Linux, CentOS 4.5 to be exact) that when a pptp client makes a connection to a pptp servcer (does the call), the server actually assigns (or more like "picks") the next available ip address from the ip pool you provide, even before it examines the login and password from the client? If so, then not only can you not specify a specific VPN IP address for a client, but also (assume the IP pool is 10.0.0.26-29 and 10.0.0.26 is the only one in use), even if the client specifies 10.0.0.29: in the /etc/ppp/options.pptp file, if 27 is the next available one, it will use 27 instead of 29 and fail, even though the client requested 29? If this is true, is there any way the client can always get the same IP address (other than just by happenstance logging in when it is the next available)? I notice that pptpd on the server spawns a pppd process with like 10.0.0.98:10.0.0.27. This pppd is spawned by pptpd when the connection. Anyway to intervene in this spawning and change the ip to what I wish (i.e. 10.0.0.29). By the way I know one thing you are thinking, but I can't have an ip pool of just 1, because we have at least 3 or 4 clients which need to connect. -- To unsubscribe from this list: send the line "unsubscribe linux-ppp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
