Hello, For the second time I tried to implement Tom Shinder's scenario regarding gateway to gateway L2TP but did'nt succeeded : Here is my question : when implementing on internalvpn ISA the server VPN for externalvpn isa server and after this later accepted the first one I have the following : In RRAS ports on each side a PPTP VPN port is open this ok: In networks favorites I have an entrance connection settled in EXTERNALVPN server but it is greyed Nothing in INTERNALVPN I understood that after this config my tunnel should automatically be working at least for VPN PPTP Then I should be able to settle a certificate on the external server and start working with L2TP What I am not doing for this to work (I cannot ping from the CLENTDC to the EXTERNALDC) thanks Any idea when the scenarios Tom was preparing will be available for sale ?
