Routing between two local networks

Hi

I need to route from 10.20.1.0/24 to 10.68.39.160/27
We are using 10.74.3.225 and 10.74.3.225 to route the traffic.
My main routers default route points to my firewall.

10.20.1.0 lives on my network.
10.68.39.160 lives behind a vendors firewall, on our campus.

10.74.3.226 is assigned to an optional interface on my firewall.
10.74.3.225 is assigned to an interface on the vendors firewall.

I have two routes on the firewall for this

10.74.3.226=>10.74.3.225
10.74.3.225=>10.68.39.160/27

When I ping, the vendor see traffic coming from 10.74.3.226 instead of 10.20.1.0/24

They need to see that its coming an 10.20.1.0/24 address, so they can respond accordingly.

Any ideas?

    Is there a dynamic NAT statement for 10.20.1.0/24 to 10.74.3.226 (the optional interface) - assuming no IP conflicts, you would not want a NAT statement here (ie. IP addresses need to pass through as-is).

    There is no dynamic NAT.
    Now, the interface on my firewall should/could be an optional interface, correct?

    Turns out that the vendor had a misconfiguration in their routing table.
    They only allowed traffic from 10.74.3.226, after their change we can ping from 10.20.1.0/24.
    Thank you for your help.
