Hello,

I've got EFM connection (UK) from BT without router option. When I'm connecting just computer, connection working, but when I'm connecting Mikrotik using the same settings, internet is unreachable, I can't ping anything in the internet. And default gateway although i can ping it, is unreachable. On the same router I have another internet connection as well, but when I tested and switched off other connection, it didn't work either.

Where am I doing mistake?

Thanks

What config are you using?

EFM is connected to the ether4, there is IP 81.x.x.x/31, default gateway is 81.x.x.86 => unreachable and I also set the masquerade on ether4, I am using RB2011UAS-2HnD, port ether4 has standard settings.

I suggest that you upload your config - output from /export compact. I'm not sure what you mean by "standard" settings - perhaps you ran a quickset script?

here is the exported config...
