Setup of 2x crs328-24p-4s+rm: Questions

Dear all,
I have some questions related to a desired set-up and some issues which don’t work - any input/feedback is appreciated, thanks!
Set-up:

  • Router “0” (ISP) → Router #1 running RouterOS (CRS328) → Router #2(CRS328) running RouterOS
    Router 0 to #1: RJ45 to ETH1
    R#1 to R#2: Fiber via SFP1 to SFP1

Scenario:
I would like to have separate networks for the ISP Router#0 and the both MikroTik Router#1&#2

  • R#0: 192.168.178.xxx
    R#1&2: 192.168.88.xxx

Connection of R#0 to R#1 is fine, R#1 gets all necessary data:

R#1: Router Mode / Port: ETH1 / Automatic Address acquisition
Internet: IP: 192.168.178.59 / 255.255.255.0 / Gateway: 192.168.178.1
LAN: 192.168.88.11 / 255.255.255.0 / DHCP- Server: ON / DHCP-Range: 192.168.88.21-199 / NAT: ON

Now i would like to connect Router #2 - either as Router or Bridge (what would you suggest?)
A.) as Router
R#2: Router Mode / Port: SFP1 / Automatic Address acquisition
Internet: IP: 192.168.88.192 / 255.255.255.0 / Gateway: 192.168.88.11
LAN: 192.168.88.12 / 255.255.255.0 / DHCP- Server: ON / DHCP-Range: 192.168.88.205-239 / NAT: ON
Problems:

  • when connected via RJ45 to R#2 with a Computer, I can’t access the Internet, e.g. google.com (ping of 8.8.8.8 works though from the Router#2 console and connected PC)?
  • what setting am I missing?
    B.) as Bridge
  • Automatic Address acquisition / Address Source: Any

→ in this case the Router can’t get an IP (0.0.0.0) and won’t do anything → have to connect via WINBOX and reset or manual configure the switch.

  • Manual:

Static / 192.168.88.12 / 255.255.255.0 / Gateway: 192.168.88.11 / DNS: 192.168.178.1
→ Internet via a connected PC to R#2 works in static Bridge mode, but weirdly I get IP-addresses assigned which are out of R#1 range (i got 192.168.88.207)

Summary:

    • ideally i would let the both Routers run as Routers & DHCP-Servers - is that possible? what am I missing for case A.)?


    • if in bridge mode, why do i get these out of range IP-addresses?

Thanks in advance for any help/feedback.
Cheers
