wlan bridge does not bridge

I have set up a wireless bridge between two routeros devices.

one set to AP bridge, the other one set to station pseudobridge.
this is to connect one of my local PCs to my local network (because I cannot use cabel…)
Not NAT inbetween. I want it to be completely transparent. like a direct cable connection. NAT only to the internet with a noname-DSL-Router.

The bridge seems to be running nice. I can ping all lan and wlan interfaces of this mikrotik bridge and also all devices with local IPs beyond the bridge. (my dsl-wlan-router, other local PCs, printer, …)
But I can not access the internet or ping any device that is behind my DSL-Router.

config on the PC is ok, I have tried it with a cable.

I am new to mikrotik wireless, maybe someone knows what to do…

Couple things to check. First:
/ip route
to see if there is a default route to the internet.

(EDIT: This is only if you are a static ip. If you use dhcp, then this should be done already.)
/ip route
add gateway=xx.xx.xx.xx

Change xx.xx.xx.xx to the gateway your ISP issued you.

Second: Cablemodems are fussy. They do not like changing mac addresses using the same ip. Sometimes you must power down the modem for up to a minute before they will accept a new mac with the same ip.
.

also, you may create a dynamic wds on the router that is at the side of your dsl router. then change the mode of your ap bridge to brdge and the pseudobridge to stationwds on the other router. bridge both wlan1 and eth1 on both routers. this way you dont need ip route. the two routers will be bridge transparently and you will have the same network on both ends. i supporse thats what you want to achieve?

ok, i reconfigured.
