Internet<====>SpeedToutch Modem<====>MT<====>Users

please give me suggestion in details.

Where do you want to get access,
which device is used as source device,
which services do you need?

thanks frind to help
I want access to winbox as admin from any where in the world..

which device is used as source device
I dont know what you mean!!

which services do you need?
I used PPPOe client and I can access to MT from internet but the users behind MT can not browsing!

I think I have problem with Routes!

Does MikroTik route use public/routeable IP address ?
There should not be any problems to access it, if the answer to this question is positive.

Make sure you have added masquerade rule,
as well probably it is necessary to adjust MTU/MRU,

Like Sergejs say,

You must have Public IP (if you useing pppoe as your gateway, in most cases your pppoe ISP give you an Dynamic/Static public IP address. You must use/have static public ip address.).

Your masquarade is not ok!

/ ip firewall nat
add acction=masquarade chain=src-nat src-address=192.168.CCC.DDD/24 out-interface=pppoe-out
