I want to change the cesurity level, so that eth0 is trusted and I can telnet in on that device. I can ping the eth0 card from another computer on the LAN so there should be no problem there.

Whenever I try to alter the settings thru 'Security Level' using the Gnome Desktop, it fails. I get prompted to confirm the change (Are you sure you want to do this ?) and click yes. But when I go back in, it is again set for High Secrurity Level and 'Standard Firewall Rules'. Rebooting doesn't help either.

What do I need to do to get this working ?

try to reinstall redhat-config-securitylevel rpm.
