I have some problem with RRAS in windows server 2008 R2. I configured RRAS with single NIC and NAT to give my clients internet access and all thing is ok until one of the clients disconnect its VPN, after that my server lose its connectivity and need restart to operate properly agian. I know it is not appropriate to configure VPN server with single NIC but there is no other option. I mean I can not add any other NIC. Also I have some static routes in RRAS configuration to prevent internal traffic and enable clients to connect to my server like this :
distention : x.x.x.x
mask : 255.255.255.255
gateway : 127.0.0.1
when x.x.x.x is server valid ip address and server local unvalid ip address without this route after first client connect my server lose its connectivty
what I must do?
