[solved] routing / firewall problem

Hi

I have a bit of a problem with my router, maybe some can help. So, i have a setup with three networks, all providing dhcp, dns and internet nat:
eth0, connected to the dsl modem [192.168.100.100]
br0, wlan/lan bridge [192.168.0.1]
ath1, another wlan [192.168.101.100]

Its working quite well. The problem is, today i observed that i could ping (as well as ssh) throughout all three networks, eg from 192.168.101.123 to 192.168.0.100. Thats new, as well as not intended. Really, really not intended. I have never set any routes explicitely, and have pretty paranoid firewall rules.

current routing table:

default         *               0.0.0.0         U     0      0        0 ppp0
192.168.0.0     *               255.255.255.0   U     0      0        0 br0
192.168.100.0   *               255.255.255.0   U     0      0        0 eth1
192.168.101.0   *               255.255.255.0   U     0      0        0 ath1
lo1.br01.acham. *               255.255.255.255 UH    0      0        0 ppp0

I suspect theres the problem, but since networking stuff has a very high propability of confusing me, im not sure. I have tinkered around a bit, but except of learning a bit about how ip replaces route (and stuff), i got only a headache and some thousend open tabs.

So, F1, please

PS: Im really baffled, the last time i needed such an effect, i had a mildly funny hour or two, trying to find out how to achieve it.

PPS: I have a slight feeling of not seeing the obvious.

*EDIT*
I was right, i obviously deleted one rule. As this now has no information anymore, please delete.
