Mikrotik forward traffic to another gateway

Question

I have problem with setting Mikrotik to forward specific packets to another router.

Our devices is setup like this:

LAN1: 192.168.1.0/24
Mikrotik: 192.168.1.253
Cisco: 192.168.1.252

LAN2: 192.168.2.0/24
Cisco: 192.168.2.252

Main gateway setup at DHCP is 192.168.1.253, so every packet is sent to Mikrotik.

I have setup up route at mikrotik like this:

/ip route add dst-address=192.168.2.0/24 gateway=192.168.1.252

Now, I can ping devices on 192.168.2.0/24, but 192.168.2.0/24 can't ping us back, except 192.168.1.253, which is mikrotik router. So, it would seem, that Mikrotik won't forward all 192.168.2.0/24 packet to 192.168.1.252

Is there anything I need to add?

Thank you

UPDATE: Actually, my problem is, that 192.168.1.0/24 can reach 192.168.2.0/24 without problem. But 192.168.2.0/24 can only reach 192.168.1.253, but not other IPs in 192.168.1.0/24. I recorded packet incoming at 192.168.1.253, but the mikrotik wouldn't forward them to 192.168.1.252

Solution 1

After some sniffing, it seems that I need to take down "invalid connection state" in firewall for internal LAN There are 3 ways of solving this.

1. Set cisco to send EVERYTHING to mikrotik at 192.168.1.253, including every packet that destined to 192.168.1.0/24, despite it is local.
2. Tear down "invalid connection state" firewall rule for packets incoming to local

3. Set up private network with /30 net specific between mikrotik and cisco like:

   • mikrotik: 192.168.1.253, 192.168.10.1/30
   • cisco: 192.168.10.2/30, 192.168.2.252/24

   then route every packet to 192.168.2.0/24 to 192.168.10.2/30. This third option is not available to me, but I put here to give you another option.

Solution 2

if the router that links both networks segments is the cisco, why are you adding routing rules to the mikrotik? just add them to the cisco
