Dear all,
In my office i using 2 connection (Wireless connection direct to ISP "A"
and backup connection to ISP "B" with ADSL Modem), how to configure Linux
iptables (gateway) so when connection to ISP "A" down client can still
work with ISP "B" without reconfiguration at client computer (see network
diagram B).
