Non-NAT Static Routing

Tue Jul 29, 2014 5:08 am

Hi All,

I've been a lurker for quite a while, but this is my first time posting.
I've tried searching through the forum for similar topics, but haven't had any luck.

Here's what I'm needing:

I've been given a IP from my ISP.
I work for a company that has given me address space on a subnet.
They've given me 6 usable IPs (/29).
I'm working with a RB751U.

I feel like I'm doing something wrong here, and I'm looking for advice.
I need my router to allow public access to devices on the space.
I'd ideally like to have publicly accessible servers on this Mikrotik.

Network: (ISP gateway)
eth2 (master port for bridge-local):

I can ping out to the internet through eth1, but I can't get out to the internet on any devices I statically assign from the bridge-local interface.
From eth1, I can ping any IP.
From eth2/bridge-local, nothing.
From my test machine, which I'm statically assigning ( is g/w, is s/net mask), I can ping the (eth1) interface (NOT the .1 ISP Gateway), the .89 address, but not anything external.
I can ping myself (.90) from bridge-local (.89).

Routes are as follows:
Dest: GW: reachable eth1-gateway Pref. Src:
Dest: GW: eth1-gateway reachable Pref. Src:
Dest: GW: bridge-local reachable Pref. Src:

I feel like my subnets aren't able to communicate, but I can't figure out how to resolve my issue.
Any and all input will be much appreciated!
Let me know if there's any other information I can provide.

your isp gateway router must have a route towards your interface:

destination with gateway <your router's wan ip>
Device: RB2011UIAS-RM, RB750GL, CISCO SG300-28, UNIFI UAP-LR
