Layer7 Installation use of Network Interface Cards (NIC) - question on routing

  • 1.  Layer7 Installation use of Network Interface Cards (NIC) - question on routing

    Posted Jul 29, 2022 03:23 PM

    Background:

     

    We are setting up a Layer7 Gateway with 2 NIC cards.

    We want one card to connect to our "application" network (target 10.32.27.138), and the second to connect to sites and services in our "external" network, including the Policy Client, GMU, NTP server and other administrative functions..

    We have firewalls in both networks between the Gateway and the endpoints applications.

     

    In our test network, both NICs are on the same VLAN and subnet, and have the same gateway.

     

    The IP addresses on the NICs are .86 (ssg_eth0) and .249 (ens192)

     

    We have added a static route using "ip route add 10.32.27.138 via 10.133.112.1 dev ens192"

     

    We were expecting this to route to go out through ens192, and pick up a source IP of .249, but it seems that all traffic is getting a source IP of .86.

     

     

    Question:

     

    Do you have any guidance on what we might try?

    For example:

    We could switch the addresses on the cards?

    We could put the two cards into to 2 separate VLANs.
