Need pptp- or l2tp-client to ISP

Jochen Held

Hi,

i Need to Setup a pptp- or l2tp-client-connection to a isp, which gives me over this Connection a fixed IP-address.

How it is possible to Setup this Connection?

 

Regards

    I Need the mail-traffic (Exchange-Server) to receive and send through the ISP with the fixed IP, using the dynamic-ip-ISP-A-connection.

     

    Explanation of the installation:
    * ISP A with dynamic IP connected through a Fritzbox
    * ISP B with fixed IP based on a VPN-Tunnel routed through the Connection of ISP A (L2TP or PPT or OpenVPN)

    * actual i use a Sonicwall 2040: X3 is the WAN-Interface (exposed host of Fritzbox) and X1 goes through the guest-function of fritzbox over the ISP A with VPN to the ISP 2

    * the connection to ISP B is solved as a L2TP-connection (Client) and all mail-server-traffic is routed through this tunnel.

     

    i try to Setup the XG in a similar way as the Sonicwall.

    Jochen,

    for the incoming traffic, edit the MTA Firewall Rule, XG creates when you switch to MTA mode. Use outbound address:

    https://community.sophos.com/products/xg-firewall/f/firewall-and-policies/94268/xg-in-mta-mode-with-multiple-wan-ips

    For the inbound, if you have create MX records only on one Public IP, this should be enough. XG automatically listens to all WAN IP.

    Thanks for your reply. I think i haven´t expressed myself or my problem clear enough...

     

    I need a solution of a L2TP/PPTP-client which connects to the ISP (it is portunity.de) and gives me a fixed public ip-adress through the vpn-tunnel.

    With e.g. sonicwall or pfsense i can setup additional interfaces on the firewall, which makes the public ip available for ip-routing.

     

    With XG i don´t find something like a interface with L2TP/PPTP-option. In the area of the VPN-settings i only find L2TP-Server, but no client.

     

    in earlier discussions on Sophos-community a few years ago they announced this as a feature in future versions.

     

    Possible solutions for this L2TP-Access should be a.) a client on the exchange-server, b.) on the firewall and c.) on the router in front of the firewall.

    Version a.) is too insecure for me, version c.) is actual not possible with the fritzbox and b.) i solved with old firewall as an interface.

     

    I hope i could explain the requirement a bit better.

     

    Regards

    Jochen,

    under Authentication > User > User A (for example), you have L2TP and PPTP fields where you can configure the leased ip for that user when it connects using one of these protocols.

    Hi Luk,

    thanks.

     

    But i think I need the other direction. XG must initiate the Connection to the L2TP/PPTP-Server of the Provider as a client and this Provider assigns the fixed IP to the Connection.

     

    Regards

    XG cannot act as L2TP/PPTP client. As VPN Client, only SSL and IPSec are supported.
