The container fully supports iptables and nftables internally.

There are many vpn services that require iptables and nftables to work correctly.

RouterOS lacks kernel modules xt_TPROXY, nft_tproxy, nft_socket.

Hopefully, v7 will be implemented in a later release.

It will be great if the tproxy is supported.
then udp transparency will be solved. for now, redirect mode only handles tcp traffic.

Yeah, that would be great if these modules have been added.
