Hi, I have a point to point, in one end has a mikrotik (RB450G) connected to a fiber and in the other end has other mikrotik (RB1100AHX2) to get connectivity from fiber side. MPLS+VPLS is the way that I use to transport internet.

The trouble.... RB1100 can´t update cloud, I can´t access to this router because say "DDNS server received request from IP xxxxxxx but your local IP was xxxxxxx"

Two Mikrotiks has on each "point to point" interface an internal IP such as 172.16.0.x

I tried to enable in advance "use-local-address" from no to yes but no lock... say timeout

RB1100 has internet connectivity, in console ping to 8.8.8.8 works perfectly, clients can surf internet...

Anyone can help me to solve this?

Thanks!!
