Issue with RB1100AH X2 (v5.8)

RouterOS General
1

Hi guys,

I’m new with Mikrotik Routerboard. I’m setting up a simple network.

I have a WAN interface (Port 1) with IP 10.185.145.253. The next hop, which is a VSAT modem, is configured for IP 10.185.145.254.

The LAN interface (Port 2) has IP 10.185.145.17, connecting to a PC/Server with static IP 10.185.145.19. All of them are under subnet 10.185.144.0/20.

After connecting all equipment, I’m unable to ping 10.185.145.254 from the PC/Server. However, after I ping the WAN interface 10.185.145.253 from the PC/Server, I can already ping 10.185.145.254 successfully. I’m not sure what’s causing the idling on the interface.

This becomes a problem when the router reboots due to power outage, etc. They need to ping the WAN interface first, to allow the communication to become active.

Any reason? Is it a firmware issue? This is v5.8.

nothing wrong with the router, routerOS, or even the firmware.

your WAN ip address 10.185.145.252/30 is a member of your network 10.185.144.0/20.

so you should change your network ip address

Hi,

Thanks for the response. But it does fall under the subnet because of mask /20. So do you mean it will be stable if I change it to 10.185.145.xx/20?

I just followed the setting on the previous router. Hope you can clarify. Thanks again!

What is the netmask on your WAN?

If it’s /30 then your two networks overlap.
If it’s /20 then LAN and WAN are in the same network, and you should be bridging LAN and WAN, not routing between them.

In either case, I’m surprised anything is working.
