I did a little experiment with webconfig configuration, to configure ClearOS 6.2 ip setting
1. My server has 2 nic, ppp0 (pppoe) and eth1 (LAN). All goes well.
2. Then I delete ppp0 and replace with eth0 (Static External)
3. Then I delete that eth0 and create new ppp0 (which same configuration with point 1 above)
4. Surprisingly, ppp0 not want to dialing modem, it shown warning like this "ppp0 device does not seem to be present"
Anyone know the solution?
