I've been messing with this for a while. Went through the forums- changed MAC to reflect old router, looked at firewall and NAT, established default gateway/route, checked on DHCP client....and I still CANNOT secure an IP address from my ISP. I talk with the ISP and everything looks good from their side...they see the Mikrotik MAC, and the link looks healthy....what am I doing wrong? Appreciate any help- I was relatively new to RouterOS...though I've spent a lot of time with it lately.... after a few restarts and resets- most of the settings are 'defconf'- I have to establish an internet connection before properly segmenting the network...didn't anticipate this hurdle. Old router/hardware still works well, and an IP address is dynamically assigned to my router by the ISP. Again- thanks in advance for thoughts or guidance!
