IPSec tunnel between two local subnets (no Internet)



  • Dear All,

    I'm total beginner, if it comes to networking.
    I'd like to test performance of IPSec tunnel between two local subnets (no Internet).

    Could you please tell me, is that even possible to establish such a connection and will I be able to perform such a test with the equipment that I have ?

    My hardware is:

    • main PC equipped with Intel Quad Port NIC (I'd like to run 2 virtual pfSense machines on it, 1st running as VPN server, 2nd running as VPN client).
    • 2 laptops, each with single port NIC (I'd like to run Iperf server & client on each of them - connection over IPsec tunnel without access to the Internet).
    • 2 Cisco EPC3928 routers

    Kind regards
    Rodak



  • Yes, thats a piece of cake. Set up your hardware and establish an IPsec tunnel between both locations.
    Then take a simple, protocol independent cli performance tool like iperf3 oder netio
    https://iperf.fr/iperf-download.php
    https://web.ars.de/netio/
    to measure your throughput in different paket sizes.



  • Hello, thank you for response.

    Could you please just give me an overview, how the basic setup should look like?

    I have prepared a basic scheme of my network setup.
    Is this a proper setup, or my way of thinking is wrong?

    Yepp, thats perfectly correct !
    You can use either IPsec VPNs or a OpenVPN based VPN. The pfSense gives you both options !
