We have a ADSL external modem and we are planning to buy an extra Leased Linegfor connection redundancy, ADSL modem works as a DHCP and connects to server via ethernet,
I guess Leased Line will have a router which gives real IP configuration to and another ethernet card,
Now the question is it possible to use ADSL connection first but if it losts connection server automatically switch to the Leased Line,
PS : ADSL is not shown as dial up connection, just an ordinary ethernet connection with a 10.0.0. or 192.168.0. class IP
but the Leased line will have real IP
thanks all
