I believe I have now eliminated all network components like routers/switches and firewalls, only different left is the version of SLES. Below is the output from: - uname -a - cat /etc/*release - cat /etc/sysconfig/network/routes - route -n - ifconfig for both machines, first the one that is working ok (zlin1016) and then the one where you only can login using one IP, for the moment it is the last IP at eth2 (zlin0068).
