two ethernets problem

Hi all
I have a mikrotik 2.9.2 with one wireless atheros connecting to a
wireless network (as station) and 2 ethernets connecting two lans
to the router.
I have a bridge with ports the two ethernets on the router.
My problem is that from the lans I cant ping the wireless network
and vice verca from the wireless I cant ping the lans.
If I use masquerading everything works (from lans to wireless
not the other way ofcource).
This happened when I changed the IP of the bridge.
routes are ok (on the remote router) and on mikrotik.
I have no firewall set up.
I have rebooted many times and the same problem.
My configuration:

on mikrotik
-------------
wireless ip: 10.184.2.33
bridge ip: 10.184.6.150 (with two ethernets)

routes:
10.184.2.0/24 gateway 10.184.2.150 (remote router ip)
(also the routes added by mikrotik)

on pc's on lan
----------------
ip: 10.184.6.1
gateway: 10.184.6.150


on remote router
-------------------
10.184.6.0/24 gateway 10.184.2.33


Any help;

I have read somewhere in this forum that
I must enable ntp client and netwatch.
Ntp client to which ntp server;
netwatch which interfaces;
Why is this necessary;

Any HELP;

ntp and netwatch have nothing to do with wireless not connecting. you must properly configure your router. you give too little details for us to know the problem

two ethernets problem

Thanks for the reply.
It is a very basic setup.
On mikrotik pc there is a wireless atheros card configured
as station to a wireless network. The ip is eg. 10.184.2.33
It is working fine.

Also on mikrotik there are two ethernet cards (eth1 and eth2).
I have enabled them and I didn't gave them any IP.

I have created a bridge with ip 10.184.6.150 and added
two ports, eth1 and eth2 and enabled the bridge.

On eth1 a pc is connected with ip 10.184.6.1 and on eth2
another pc with 10.184.6.200. On both pc's default gateway
is 10.184.6.150.

On mikrotik I have a static route for network 10.184.6.0, to
10.186.2.150 (remote router, not mikrotik).

From mikrotik i can ping everything, remote pc's on
the wireless interface (eg 10.184.2.40), and also
I can ping the 10.184.6.0 network.

The problem is that I cant ping from the inner pc's
(eg 10.184.6.1 or 10.184.6.200) the wireless network
(eg 10.184.6.40) unless I do masqurade.

I now that in FAQ it says to configure the remote router
(or isp) but I have done that (for example added
a gateway 10.184.2.33 to network 10.184.6.0).

Any help;

Never mind.
The bridge on mikrotik works fine.
The problem was with the remote rooter.
Thanks
