sorry for beeing late with my reply. I think I solved it.
The setup was as described in "perfect setup".
But Due to the shorewall-firewall layout I do have to have a split brained DNS.
editing resolv.conf with the very first nameserver as 127.0.0.1 did it. ( the lan adress is 192.168.0.2 which caused DNS queries to be answered for 192.168. and not with the external settings at 127.0.0.1)
Thank you for your guidance.
CentOS 5.1 in vmware 1.0.4 was dead slow -becoming better now.
Critical: using mc for fileops on the md0 array (the 2 drives are defined as sdb and sdc in vmware.vmdk? is drowning the CentOS Server!
installing vmware-tools is an adventure - my kernel should be patched
drivers/input/serio/i9042.c claims tainted kernel due to some licensing problems of the vmnet drivers.
really a mess
