adding eoip interface to bridge breaks internet

Sat May 11, 2019 10:01 pm

Good day.
I am running the latest mikrotik x86 routeros within phpvirtualbox
Everything was working fine until recently.

I have interface bridge with ports ether1 , eoip1 , eoip2 etc

The problem is that suddenly i am unable to access the routeros via winbox with ip address.
I can only when using mac method.
But after i disable the eoip ports within bridge interface then sudden everything works again.

It was working fine for 4 days now, only started doing this today.
I have not modified and rules or any settings.

I had similar problem and I solve it changing MTU=1500 for the EOIP tunnel
