So, my cable modem is giving out addresses 192.168.0...., it gave mikrotik router 192.168.0.11. mikrotik is using its own DHCP and giving addresses 192.168.88.1-.... I am trying to connect to NAS that is on 192.168.0.14. I can see it in the browser and ping it from my computer on 88. network, but I cannot map the drive or see it in the network. What would be the easiest way to configure this network so I can access the shares from my computer behind the network. thanks!

Make only 1 network segment and connect directly to the NAS,
Why you put the MikroTik in between with routing (and probably also NAT)?

it was a leftover from my old network where mikrotik was dialing the pppoe connection to adsl modem. now i just switched it to dhcp and let the cable router give me ip, and the rest is unchanged. i wanna know what would be the best way to connect it so all are on the same dhcp. also cable router is 1gbit, and mikrotik 100mbit, but i need it for USA VPN IP access, so i keep some stuff behind it. i might just buy RB260GS and put everything behind it again...

Just disable all DHCP stuff on the routerboard and add all ports to the same bridge.
If bridging all ports, it is just like a switch.
Give the MikroTik an IP address for management only (in the 192.168.0.x segment)

ok, i need a rule that will enable my pc on 0.12 to talk to nas on 88.27



thanks!

I still would suggest my earlier solution.
Bridge all ports on the MikroTik and let the DCHP on your cable modem assign addresses to your NASs (or put static if needed)
