Static routing: different paths for request and response

jambonorange
Hi !

I'm wondering how Sophos routing works.
I'm using Sophos UTM9.
During some tests, I discovered that the host that send the request packet to sophos has to be the one sophos sends the response.

Example:
Host A sends TCP request to sophos. Sophos routes the packets. The response arrived to Sophos. Sophos should be routing this response to Host B because of the static routes. But Sophos does not do that.

Is that normal ?
Is sophos a "stateful router" ?

Thank you !

    Masquerading?

    If that's not the problem, show a representative packet (IP -> Service -> IP) that you want the UTM to receive and the IP of the device to which you want the UTM to send.

    Ok let's say i've got something like this:



    Host A ping Host B.
    The routes I have added make the request goes:
    Host A --> Sophos --> Router 1 --> Router 2 --> Host B
    And the response:
    Host B --> Router 2 --> Sophos --> Host A

    And I think that sophos does't want to forward the response because it "sees" that Router 2 shouldn't be the one sending the response. It should be Router 1 (because Sophos sent the request to Router 1).

    I hope I'm clear ! [:$]

    There's not masquerading

    Thanks in advance
