I have a scenario where I need to pick up an existing (non Mikrotik) 802.11 AC signal and retransmit it inside a metal boat so that users in the (static) boat can use the site wireless. My current thinking is to use an SXT AC externally, linked to a HAP lite internally via ethernet cable. My question is this; If I link the 2 Mikrotiks using an EoIP tunnel can I use the wireless repeater package to link the wireless interfaces of each device and so repeat the external signal internally?

No need for EoIP tunnels, just set the Hap lite as a simple wired/wireless switch

No need to use wireless repeater, as both will be already connected via ethernet which is also the optimal approach.

That looks great pukkita, thank you. Much simpler than the setup I was trying to figure out.

Will DHCP pass over the link from the existing network with that setup?

Yes.

Finally got back to this set up this week, just wanted to thank pukkita for the set up info, it works great and does exactly what I need it to. Thanks for your input.
