Extension MASQUERADE revision 0 not supported, missing kernel module?

[mskopek]

Hi everyone,
I moved from a dedicated Ubuntu server with a working Wireguard / wireguard-ui system to Synology ds1817+ with Container Manager and Portainer.
With the latest release v0.6.2 I get the following error message:

[#] iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE; iptables -A INPUT -p udp -m udp --dport 51820 -j ACCEPT; iptables -A FORWARD -i wg0 -j ACCEPT; iptables -A FORWARD -o wg0 -j ACCEPT
Warning: Extension MASQUERADE revision 0 not supported, missing kernel module?
iptables v1.8.10 (nf_tables): Could not fetch rule set generation id: Invalid argument

With the release v0.5.2 everything is working fine.
Anyone else who have this issue and maybe a solution?

Thank you very much.
