Before starting the script i tested the routing of the setup, and everything worked.
Are you sure? x.y.z.129/25 x.y.z.132/25 x.y.z.133/25 x.y.z.134/25 and x.y.z.153/25 all belong to the same subnet (x.y.z.128/25). It's not possible to route with this setup. You could split your network into more subnets, say x.y.z.n/27, and then distribute your hosts accordingly.
Maybe it's the fault of my unusual setup:
internet C A | <____.y.z.153/25____.....______x.y.z.132/25______x.y.z.129/25 x.y.z.133/25 D / / x.y.z.134/25 B
(A:firewall, C:admin-comp, B:webserver, D:default gateway)
I'm sorry to say that there's no way to change the network (subnets, etc.) - not my fault...
Any ideas ?
Thank you in advance and sorry for the longish posting ! Tobias
