And either delete or enable/disable the NAT rule to see if it has a problem.

No, It should not be required. I run my entire network on privates and
only put publics where I need them. You have
something fishy with the config. do you have 10.100.0.1 on the
upstream router? If so, get rid of the 207.235.20.16
IP and keep the 10.100.0.2 then default route over those for 0.0.0.0/0
and 207.235.23.0/26. should work fine. If not,
you still have something wrong in the config.  I find it best to
delete the default config even if disabled.

Ok I got it finally. I have 10.100.0.2 AND 207.235.20.16 on ether1. I have
207.235.23.1/26 on ether2. I have default route to 207.235.20.1 (edge). I
have return route from edge for 207.235.23.0/26 to 10.100.0.2. My laptop
with 207.235.23.3 connected to RB ether2 can get online now.

Is a public necessary on the outbound interface of the RB in order to get
online? I take it that it is and that is why it hasn't worked til now.

That is what I thought but when I look I see:

/ip firewall nat
add action=masquerade chain=srcnat comment="default configuration"
disabled=yes out-interface=\
     ether1-gateway

Is it just a bug and is somehow stuck in NAT even though disabled?

Another example - when I ping from my machine behind the router the
failure is "Reply from 10.100.0.2: Destination host unreachable."

The router with address 10.100.0.2 is doing NAT.  That is the only way I
can see that you can have that address as the source on your outbound
traffic.

Okay, after putting out fires for a few days I am back at looking at this
issue. What I have found is that traffic from me on the
207.235.23.0/26subnet is leaving ether1 on the RB like it should but

as a result is
leaving AS 10.100.0.2. Since that is a private address it is not routable
beyond my edge. That makes sense. I replaced the private ips between the
two routers with public addresses and while I do have connectivity with
the
world that way, it is only because I am routed as the new public IP
assigned to the RB's ether1. NAT is NOT enabled. Can anyone verify my
thinking or explain what SHOULD be happening here?

I am trying to route my first tower with mikrotik. I have a private

to use for clients of this AP and the gateway for those is set as an

our edge router. There is a route on the edge router routing that

me.


This all sounds correct to me.  From a connected device on the lan
side
(the 207.235.23.0/26 block), you are able to ping everything inside

your
network, but not beyond that?  I'd doublecheck to ensure there is NOT
a
NAT rule in place on the MT that is causing this issue.
