Hi, there, For the servers that I use pppoe I use to create scripts that tests the connection to the internet, and, in case of a problem, they restart everything (logically speaking). Things I use to care: - Kill the ppp process and destroy tun interface; - Put interface down for 2-3 seconds; - Clean arp tables; After that, when the script turns ppp on, everything works. If the problem is with the physical equipment, I once use python with telnet module to automatically log via telnet on the modem and send the command to reboot it.
