Modbus RTU over SoftEtherVPN (L2TPv3)

Hey all,

Has anyone had Modbus RTU traffic flowing over the L2TPv3 etherIP protocol VPN tunnel???
We are running L2TPv3 tunnels between Cisco IR modems and the SoftEther VPN server and have a requirement to send Modbus RTU traffic over the VPN.
However it is proving difficult and not exactly working.

Also wondering whether there is an incompatibility between Ethernet2 frames and 802.3 frames.
- We seem to be able to establish comms via Ethernet2 frames but not 802.3 frames on some Schneider equipment behind our Cisco IR modems.

Any advice or experience would be appreciated.
