Sure, get the mac address of the TP Link, decide on the hex what IP you want to give it, then add it manually on the hex via dhcp leases.....
Go to your TPLINK put that IP address as a fixed IP address on the TPLink and you will be up and running.
What model of TP LINK ( probably not vlan capable )..........
hey, sorry for the late response, i just got around to this.
So mikrotik is working fine, i connected it from eth2 to WAN port on TP link. I can see it was given an IP via winbox table but i cant connect to it anymore. IP scanner finds it aswell on the given ip but im getting no response from the router.
