I've just got a Mikrotik RB2011 router which I am going to use as the main 'hub' router on my home LAN. Since it doesn't do ADSL itself and I don't have any simple 'modem only' (yes, I know they're not really modems) ADSL boxes I'm going to use my two existing ADSL routers to connect the Mikrotik to the internet.

This means that there will be two NAT routers between me (well, eveything on the LAN) and the internet. I can't see that this will cause a problem, can anyone else see anything wrong with this?

The Mikrotik will do load balancing and it has the advantage that it can handle more than two WAN connections so I can add my 3G and/or WiFi backup connection while leaving the two ADSL in place.
