Hi All
I really need some assistance.
I am asking after trying many things but have failed.

I have the following.
RouterBoard 411U - Current Firmware 2.36
RouterOS 5.6
SoftwareID NFSF-7614

Modem = Sierra Wireless MC8792V

Operation
Modem makes a 3G connection - Successfull
On the Ethernet port we have a private network.
DHCp Disabled
DynDNS successful
RB - IP Address - 192.168.0.1
PC - IP address - 192.168.0.118


Now for what we do. At the client sites we use web services and remote desktop connection to the PC via the mikrotik.

I have tried all different scripts to enable prot forwading and allow ping replies but have miserably failed.

Can someone please help me and explian it to me like im a 6 year old.

Regards
