When you configured the local vpn server wizard did you click on both the local and remote isa vpn computers can initiate communication? When you configure local vpn server and remote vpn server the remote vpn server must initiate the connection between them not the opposite ,and when the connection is establish they can talk with each other Ok this what I think Hanan.Mawla (MCSE,MCT,CCNP) -----Original Message----- From: esmondl@xxxxxxxxxxx [mailto:esmondl@xxxxxxxxxxx] Sent: 09 January 2003 17:59 To: [ISAserver.org Discussion List] Subject: [isalist] Router-to-Router VPN Issue http://www.ISAserver.org Dear all, I appreciate if anyone can shed me some lights on router-to-router VPN configuration issue. I have configured two separate networks and each of the network is configured as follows: LAN_A: Server_A (installed with ISA & VPN) IP: 172.16.112.1 / Mask: 255.255.255.0 LAN_B: Server_B (installed with ISA & VPN) IP: 192.168.0.1 / Mask: 255.255.255.0 In LAN_B Server_B machine, I have ran the "Configure a Local Virtual Private Network (VPN)" wizard provided by ISA to generate a .vpc file successful, then copy the .vpc file for remote network (i.e. LAN_A ) Server_A machine to finish installation of the remote part of the router-to-router VPN (by running the Configure a Remote Virtual Private Network (VPN)" wizard. After both local and remote VPN routers are configured, it works OK to ping a remote network machine ONLY from the Server_B (i.e. local VPN server), however, none of other networked desktops in LAN_B can ping any of the remote network machines. I have added all static routes for remote network (i.e. IP:172.16.112.0 / Mask:255.255.255.0 to all interfaces) but still have no luck for any of local networked desktops to ping any of the remote network machines. When I type tracert 172.16.112.5 from a machine (i.e. with IP 192.168.0.5) in network B, it gets response from 192.168.0.1 but nothing after this IP address. None of other desktops in LAN_B can access LAN_A excepted for the local VPN server itself . Do you know what should I do to make it to work? Any information is greatly appreciated.
