[yocto] SUMO - XT_NAT module - SNAT, DNAT symbols missing

[Prawn Hongs]

Hi Everyone,

I am using SUMO Yocto version to build for zynq machine type.
I am facing problems related to CONNTRACK SNAT, DNAT. I want to know in
this forum like is there a known issue in the kernel version supported in
SUMO.
I have tried various IP table options but I couldn't get the SNAT, DNAT
symbols identified. Here is what I am trying -

# iptables  -A FORWARD -m conntrack --ctstate SNAT,DNAT -j ACCEPT
iptables: No chain/target/match by that name

Here is my lsmod -


$ lsmod

Has anybody faced similar problems? Is it a known problem in the

kernel version supported by SUMO.
