Hello,
Why would in Winbox, Neighbors List all devices on one bridge will show gateway address instead of real IP?
Is like hair-pin NAT…
If you not put export compact of both machine, the cause can be various.
It has something to do with Bridge settings - “Use IP Firewall”. When checked neighbors will not show device IP, when unchecked all is fine. I checked its not hairpin NAT.
Only discovery on the bridges doesn’t show real IP. I don’t know if this is normal, but sure inconvenience 
Usually I leave all discovery enabled except for pppoe.
I never have that problem…
I didn’t have that problem running RB2011 on the same place. After upgrading to CCR I had to add a lot of subnets and never looked on Neighbor List until now. Perhaps it’s one of the minor “bug” on CCR ruining 6.7. Because everything what I need works I’m not upgrading to latest OS …
