Hello,

first... sorry my english is a disaster... I hope you understand my Problem.

I have a Routerboard 411 an I would connect two subnets. On ethernet interface the net is 192.168.10.0/24 and on wlan interface the net is 192.168.12.0/24. I used twe howto from "http://wiki.mikrotik.com/wiki/How_to_se ... d_Ethernet" and i get no connection between the PC on ethernet interface and the AP where is the Router connectet. The Connection between the Mikrotik station and my AP is OK. From Mikrotik I can ping to all my adresses in the net, but not from the PC behind the Mikrotik Router.
Have anyone any idea?

Thanks...

Have nobody any Idea?

Hi,

seems your routing is not ok.
So check the routing tables on all involved routers/pcs.

"route print" in windows
ip routes in winbox

*Every involved system* needs to know where to route
packets.

If this is ok check firewall rules

It seems, the routing on all other aps is OK, but I dont know, what's the rpoblem on mikrotik.
If I coonect with some other router/ap with the same configuration the connection is ok.
I think my configuration is impossible with an mikrotik device.

Don't give up to quickly. Tell us what you get when you do this;

/ip route print

my opinion is, that all connections would be routed to 192.168.12.5. I test it with interface bridge1, wlan1 and eth1.
I dont give up quickly. But I read some manuals and test since one week. Apologies please, I'm annoyed.
I have some mikrotik devices in use, but this problem exceeds my abilities.
My experience with Mikrotik has been very good. I think that are very good devices.

Ok the problem I see is that you have assigned both ether1 and wlan1 to the bridge but left the IP addresses as before.

Remember the bridge operates at layer 2 so this is a physical connection. Pretend the wireless and ethernet were joined somehow. Whilst you can physically connect them together, the network layer (3) wont work because they're on different IP ranges.

So either do one of the following;

1. Assign one common IP range to the bridge and remove the others

or

2. Remove both interfaces from the bridge and setup some routing but it may just work be default.

Hope this helps.

I change the configuration, remove the interfaces from the bridge, add routing and so on, but it don't work corectly.
I don't no, what I should do.

I found the problem and the routerboard run correctly. My problem was an error in the masquerading rules.

Thank you for your help
