I can access the VPN server without using VPN

i running server 2003. have vpn setup correctly, router setup correctly, , connecting server remote computer using vpn works great. here problem: can connect vpn server form remote computer without using vpn! cannot reveal vpn server ip because massive security hole, example lets make 1.2.3.4. remote computer make new vpn connection 1.2.3.4, connect, login, works should. now, disconnect vpn server , instead go start>>run , type in vpn server address , bingo, window shared drive on server pops open on desktop. need security hole plugged right away not encrypted connection.

hi,

 

thanks posting here.

 

could verify route setting , describe network topology, how share internet connection internal machines (is nat ?)and how set port forwarding publish rras internet ?

and 1.2.3.4 in case , internet address ?

i suspect issue may cause due incorrect port mapping configurations on internet edge router.

 

internal networking(rras) ----------------router-----------------internet networking(remote client computer)

 

please check if issue resolved configure firewall setting on rras server disable file server relate ports or disable “file , printer sharing microsoft networks”  on internet facing nic.

 

system service name: lanmanserver application protocol protocol ports netbios datagram service udp 138 netbios name resolution udp 137 netbios session service tcp 139 smb tcp 445

 

service overview , network port requirements windows server system
