My network configuration looks like this:


Client 2 connected directly to the switch is able to ping and access the webgui.

Pinging from RB450G via WinBox results in timeout.

The road warrior connected via OpenVPN with an ip in the same subnet as the switch gets a timeout as well.

This probably is a very basic problem, but how can the managed switch be reached from the RB450G?
I've tried setting up a static route and adding a NAT rule but with both I am unable to access the managed switch.

Thanks in advance

You must put a 10.0.0.x ip in the rb450 in the eth5 interface, and also enable proxy-arp in it.

The ip is needed to make the router able to ping the switch, the proxy-arp is needed to make the roadwarrior able to ping the switch.

Thank you for your answer.

I tried (again) adding ip 10.0.0.5 to eth5, but still pinging the switch is not possible.

Even with a patch cable from RB450G's eth3 to the managed switch and an ip address in the 10.0.0.x range, pinging the switch is not possible.

At the same time, a client within 10.0.0.x is able to access the switch just fine.

I don't get it..

Yeah, but does the client "ping" the switch?? maybe ICMP response in the switch is disabled.
