Hi Guys
I used to share internet(ADSL) with PPPOE setup in RouterOS and i didn't have any problems - all routers port had internet access-
BUT recently I've bought a TD-LTE modem with a LAN port(A modem with a very basic feature, You can not config this modem,you just can turn off DHCP that I've already done this. The default gateway is 192.168.1.1 and when u plug LAN port to a PC that PC will connect to internet) I connected modem's LAN port to routers wan port(LAN1)
But i can't share the internet with other port
I've made a NAT rule in firewall and other things but nothing changed
If anybody can help me i'd be happy
Thanks in advanced

I fixed it myself
