I have created an EoIP tunnel between an x86 router and a Routerboard router. They have different MACs but the same tunnel ID and I have assigned an IP to each tunnel. Both router can ping each other on the external address but can ping each other using the tunnel address. I see TX packets on the Routerboard when i try and ping but no RX packets. On the x86 router there is no TX or RX packets when pinging.
I have successfully created a PPTP connection so I know the firewalls are open for GRE.
Does any anybody have EoIP working on 2.9.10? Also how can I tell if the tunnel is successfully connected?

Is nobody using EoIP?

Yeah, it's a simple tap interface that Mikrotik renamed to make it easier to understand the purpose of it. The same goes to IPIP which is a tun iface.
EoIP allways worked for me.
Did you check your input chains ?

I've been having trouble with EoIP, it would be good to have a status indicator to know if it is running correctly or at least something in the log.

What RouterOS version(s) are you using on the peers?

I've had issues with it on 2.8.28 and 2.9.x

Allways on the same hardware or did you try to switch your nics etc and see how it acts?

I have tried plugging the router together and still I can't ping using the EoIP tunnel. Do you need a certain NIC to support EoIP like you do for VLAN?

Ok I have fixed the problem. I was dropping invalid packets, when I disabled the firewall EoIP started working as expected.

That's exactly what I told you to do in my first answer.
I am glad you solved it, good luck.

Can you check http://wiki.mikrotik.com/wiki/EoIP
and see if I got it right - updated it if it is wrong. We are getting some real gems of info here in Prague but forgot to ask about this one yet

The instructions look fine but I suggest you add a note that if you drop invalid connections on your firewall it will not work. Drop invalid connections is recommend in the FAQ on "Securing your router" so I expect quite a few people will be doing it.
