Title: LAN to LAN setup via other vendor rtr and Dlink 825
Post by: xmlfreak on February 16, 2011, 03:53:10 AM
Hello Forum members,

anybody here who has setup a Dlink 825 in a LAN to LAN VPN (PPTN/IPSEC/LT2P) setup with other vendor router, like Draytek for instance?  :)

I'm researching on what best practice to use, in connecting LAN to LAN between our HQ office and customers sites to replicate data from storage/deployment devices. I know I can use rsync in combination with stunnel, which maybe will be used!

However I'm exploring other options to see if there was an easier way to get this up and running.
Any reply would be appreciated,

Regards,
xmlfreak

You figure this one out?

Hi,

it is not possible to use DIR-825 as a VPN Gateway. It only provides ALG functions for PPTP- or IPsec-VPN-Clients on the LAN. See the description within the support menu:

Quote
Application Level Gateway (ALG) Configuration

    Here you can enable or disable ALGs. Some protocols and applications require special handling of the IP
    payload to make them work with network address translation (NAT). Each ALG provides special handling
    for a specific protocol or application. A number of ALGs for common applications are enabled by default.

    PPTP

        Allows multiple machines on the LAN to connect to their corporate networks using PPTP protocol.
        When the PPTP ALG is enabled, LAN computers can establish PPTP VPN connections either with the
        same or with different VPN servers. When the PPTP ALG is disabled, the router allows VPN operation in
        a restricted way -- LAN computers are typically able to establish VPN tunnels to different VPN
        Internet servers but not to the same server. The advantage of disabling the PPTP ALG is to increase
        VPN performance. Enabling the PPTP ALG also allows incoming VPN connections to a LAN side VPN
        server (refer to Virtual Server).

    IPSec (VPN)

        Allows multiple VPN clients to connect to their corporate networks using IPSec. Some VPN clients
        support traversal of IPSec through NAT. This option may interfere with the operation of such VPN
        clients. If you are having trouble connecting with your corporate network, try disabling this option.

        Check with the system administrator of your corporate network whether your VPN client supports NAT
        traversal.

        Note that L2TP VPN connections typically use IPSec to secure the connection. To achieve multiple
        VPN pass-through in this case, the IPSec ALG must be enabled.
