Hi Will,
If your PLC has the ability to send emails, you will have to change these settings in the comcfg.txt file to allow internet access to the LAN devices (Setup > System > Storage > Edit COM cfg):
NatItf = 2 (Nat and TF on WAN)
VPNRedirect = 0 (Allow traffic outside the VPN tunnel)
FwrdToWAN = 1 (Forward LAN traffic to WAN)
You will also need to make sure that all LAN devices are using the Cosy’s LAN Address for their default gateway.
