Routerboard 532 Noob routing question

RouterOS Beginner Basics

Hi All,
I am obviously missing a rule or policy in my setup. I have a 532, running 2.9.43, that is setup as follows:

  • Eth1: 10.255.104.3/24
    Eth2: 10.35.1.1/16 & Public IP 123.123.123/28 (example)
    Eth3: 10.34.1.1/16 & Public IP 12.12.12/29 (example)

I have a routes for above plus a “AS” route as follows:

  • Destination: 0.0.0.0/0
    Gateway: 10.255.104.254
    Distance: 1
    Interface: Eth1

When in place I can talk to the unit via Eth1 but no traffic from Eth2 or Eth3 is passed. Do I need a rule in place for each interface as follows:

  • Src. Address: 0.0.0.0/0
    Dst. Address: 0.0.0.0/0
    Interface: Eth1 (and seperate rules for Eth2 & 3)
    Action: lookup
    Table: main

Be gentle :confused:
Cheers
Steve

Do you need to NAT private addresses on ports 2 & 3 OR are you routing public ip’s?

Basically part of a wireless network -private IP’s are for management of Radio units, Customers get Public IP’s assigned statically.

Check to make sure you have default gateway’s setup on clients. Also check your routes on your routers with trace route to see where the problem is.

Thnaks for the help so far -to explain how I’ve been testing I run constant pings (using PingPlotter) to select private IP’s and public IP’s on each interface. Before we swap we make sure the selected IP’s are responding. We swap the current router (if it could be called that!) out with the RB532. The pings come in on Eth1 (10.255.104.3 -which responds) but are unable to get to their destination e.g. 10.35.0.1. We can access the unit via Winbox or Telnet.
