You can't take a 1500 byte packet, add EoIP overhead and still be within 1500.

Could you elaborate on this? We have a couple EOIP links across "other" networks and have never adjusted the MTU anywhere. I just pulled up the EOIP interfaces on each router and they are all set for 1500. Should we be increasing this number as a best practice when building EOIP Tunnels?

Otherwise, what RouterOS version?

So I have an EoIP tunnel setup over two fiber connections for a customer, I am seeing high latency over the tunnel any idea? MTU Issue? Using RB1100AHx2 on both ends.
