Hello, I have a 2 MBit cable modem with DHCP and my ISP rotate all 3-4 weeks the IP-Adresses. How can I check with a simpel and small program that the connection is broken ??? The program must force the router to rebooting ??? This must be compiled for LRP 2.9.4 (Linux Router Project). I think, it is good, if the program check the connectivity all 5 or 10 minutes. Thanks in advance for your help Webmistress Michelle
