I supposed, that this would be only an optional line, in case other servers should provide DNS-functions.
I changed it as You recommended. Also I tried to provide the DNS-Server of our TeleComm-Provider, just in case.
I also tried only offering SVR5 or the router as DNS-Server by commenting the other lines out. None did work. I also checked the routes in the client. It showed 192.168.178.1 as Gateway once and 192.168.176.1 the other time. Both times no connection to the internet.
But I can always reach SVR5 via SSH and the config-page from the client as well as from any clients connected to the Fritz-Modem(/Router).
The config Page (accessed via ethernet-cable on eth0) shows this (followed by one of the configs I tried for dhcp):
## DHCP

option 'domainneeded' '1'
option 'boguspriv' '1'
option 'filterwin2k' '0'

They are just for general internet. I wanted to use pineapples instead of some random device in order to have them at ready to occasional use their features and to support hak5 of course.
Also I didn't think that they wouldn't work in this setup.
I would like to get the pineapples to work rather then sending them back especially as I suppose that I might run into the same problems with any other router based on OpenWRT (or even more, as pineapples at least come with it pre-installed). And how would I configure them to be dumb routers? And is there a reason why I couldn't do that with a pineapple?
Also I really want to understand why it doesn't work.
