Please set the IP address 10.228.35.108 (for PROD) or 10.226.33.107 (for UAT) - as the source IP of the multicast feed.
For example: iperf -u -s -i 1 -H 10.226.33.107 -B 220.127.116.11 -p 14002
where 18.104.22.168:14002 is UAT orders snapshot feed address.
Set the filter using the following command:
sudo sysctl -a | grep net.ipv4.conf.all.rp_filter

sudo sysctl -w net.ipv4.conf.all.rp_filter=0
Please restart your software after performing the above steps.
Please check the firewall settings on your side.
