Problems connecting Continental ARS430RDI radar to Drive AGX Pegasus

Here’s my ifconfig output.
Pictures will follow (since i can only post one) of the radar harness (the upper twisted pair, pins 1 and 5, are going to the AGX, the left twisted pair is 12V and GND, finally the tapped leads are unused pins).
I’ve checked with Continental and they’ve confirmed the wiring.
I can confirm that I’m sseing packets in the configuration :
Radar – (BR+/-) → E3579 dongle – (Ethernet) → Windows Laptop.
Now I’m trying :
Radar – (BR+/-) → AGX
But I can’t see the radar on the network (I’m using port 3/4 1GbE/100MbE shown in the picture).

To my knowledge no material changes to the network file has been done.
Those are the commands i’ve tested:
sudo ifconfig eth0:900 192.168.3.81 || true
sudo route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0:900 || true
sudo route add -net 192.168.3.0 netmask 255.255.255.0 dev eth0:900 || true
./sample_radar_replay --protocol=radar.socket --params=device= * CONTINENTAL_ARS430_RDI_V2,ip=192.168.3.33,port=31122
I’ve also tried with multicast-ip parameter with different combinations based on Network configuration for Conti ARS430 - #6 by SivaRamaKrishnaNV.

I’ve also tried:
sudo ip route add 192.168.3.33 via 192.168.3.81 dev eth0:900
and ensured ip forwarding was on. I made sure no firewall rules were blocking traffic on eth0:900.

We’re using Driveworks-4.0 and radar ARS430RDI_V2 with firmware 3.0.0.

Thank you!
