Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

Scenario:

  • Windows 2003:

    • Router ports to PPTP Oppened
    • 1 LAN Adapter as "LAN Connection" 192.168.2.102
    • The two adapters are really in the SAME network
    • 2003 added to a Domain. but not domain controller
    • No other services added to the server. Only VPN added using the Wizzard
    • VPN Configured to use the range from 192.168.2.50 to 192.168.2.99
    • allow acces to the network
  • Users with VPN privileges an acces to the VPN correctly
  • All Devices in the local network

Problem:

Access to some machines on the network but not to others

  • 192.168.2.4

    • Windows 7
    • Machine in Domain
    • Access using TS OK

    • Domain controller
    • Access using TS OK
    • Access to HTTP/SVN/CVS Servers OK
    • Access to MySQL OK
    • Ping Ok
  • 192.168.2.102

    • Windows 2003
    • Machine in domain
    • RAS is installed on this PC with access from a second eth on 192.168.2.101
    • Access using TS OK
    • Ping Fail (Not allowed)
  • 192.168.2.103

    • NAS with Linux system.
    • Access using HTTP FAIL.
    • Ping Fail

    • Debian 5 servers
    • Access using SSH FAIL
    • Access to HTTP server Fail
    • Ping FAIL
    • WMWare Server
    • Windows Machines
    • Ping OK
    • TS OK
    • Linux Machines

    • Ping Fail
  • 192.168.2.253

    • Dedicated Printer

Strange problem. Appears that the Windows machines are accessible without problem but Linux machines or dedicated devices based on linux are not responding to the VPN.

Any idea to solve the access problem to some devices.

Am a bit confused with 192.168.2.103. The HTTP FAIL comment, does that mean you can ping it? –  Decado Mar 17 '11 at 12:49
    
Nop, ping also fails. –  Dubas Mar 17 '11 at 12:52
    
And where are you trying to connect to these machines from? –  Decado Mar 17 '11 at 13:36
    
Using the VPN provided 192.168.2.102 Machine using RAS –  Dubas Mar 21 '11 at 15:28
