Hello there! because of my tough semi remote geographic terrain situation to get direct WAN link from tier-1 backbone ISP provider to my NOC end i am unable to get direct connected link with its CPE to my Mikrotik router board gateway at NOC and then back to my top hill AP site. So i decided to design and implement a network topology to get a solution to fix this problem as mentioned in the attached diagram. Could anyone please assist me further how to configure and bright this WAN link to my Mikrotik RB gateway at NOC end. Please refer to the attachment for the suggested network diagram. Thanks.
