Site to site routing, over a PPP connectionFirst, say how cool the windows xpe stuff is ... I'm enjoying every bit :) Now, the problem: i cannot perform full site-to-site routing over a PPP link (over ISDN). I have two network sites (A and B). On each subnet, a win xpe machine acting as a gateway/server. They are connected via an ISDN link (ISDN to USB adapter), one being setup as dial-up server, the other as dial-up client. I also enabled the EnableIPRouter key in the registry, so that some extra routing can be done by windows. subnetA -- dialup client -----IP/PPP /ISDN ---- dialup server -- subnetB The problem: the dial-up link is set up no problem. From the dialup client subnet, i can ping into the dialup server subnet. But from the dialup server subnet, i can NOT. The further i can ping is the dialup client IP/PPP/ISDN interface IP, but not the "internal" subnet interface. I read this is normal for the PPP client not to allow its subnet to be seen/reached. But ... is there a work around? VPN? Any pointers will be highly appreciated. Cesc XP incoming connection is designed as peer to peer connection. Even you enable the IP routing, that doesn't guaranty to work. It is better to setup site to site VPN using routers or windows servers.

Thanks for the reply. The problem is that these gateways are supposed to be XP Embedded machines (thus, its OS is generated with the XP Embedded target builder tools). I don't know of any version of windows server (2003, u mean?) for embedded systems ... On the other hand, i tried to set up the VPN connection over the PPP link .... probably i did something wrong, but it did not work. It seems that the PPP client drops all packets trying to get into its internal subnet ... (it does allow ping replies to go back in ... using some kind of memory mechanism, though). I am puzzled ...
