I have installed a small Linux server; the server is in a different subnet as the internet hosts. I added a route to my nat router to create a connection between both subnets. In both subnets I use an extra dhcp Server.

Subnet A: 192.168.0.0/26
Subnet B: 192.168.1.0/26

Router: 192.168.0.1, Server in A: 192.168.0.62, Server in B: 192.168.1.62


internet ____ nat router ___ (Sub A)___ internet hosts
                        |
                        |____(Sub B)___ other hosts

I could ping every host. Also the hosts which are connected to the subnet b, has internet connection.

But sadly I have a problem with the dns server. I use the dnsServer from my nat router, I set the dns Server for subnet b to the ip 192.168.0.1, but every dns entries are equal with the hostname from my linux server.

Example if the hostname from the server is test

Test    192.168.0.62 //Server subnet a
Test-2  192.168.1.62 //Server subnet b
Test-2-2    192.168.1.1 //host a
Test-2-2-2  192.168.1.2 //host b

Any idea what went wrong? The internet dns resolution works fine.
