Hello guys, I have two ISP's connected to my router. One via eth2, second one via ADSL modem, with ppoe doing on my Centos 5 . The problem I have is, that when ADSL fails , interface ppp0 is removed. This also removes my static routes configured for this interface. I do not want that, as I have load balancing configured and default route is removed when ppp0 interface disapears. This is my ifcfg-ppp0 config : USERCTL=yes BOOTPROTO=dialup NAME=DSLppp0 DEVICE=ppp0 TYPE=xDSL ONBOOT=yes PIDFILE=/var/run/pppoe-adsl.pid FIREWALL=NONE PING=. PPPOE_TIMEOUT=80 LCP_FAILURE=3 LCP_INTERVAL=20 CLAMPMSS=1412 CONNECT_POLL=6 CONNECT_TIMEOUT=60 DEFROUTE=no SYNCHRONOUS=no ETH=eth0 PROVIDER=DSLppp0 USER=O2 PEERDNS=no DEMAND=no PERSIST=yes As you can see, I have PERSIST=yes , which according to documentation should keep ppp0 interface ON. Well it does but only for a couple of seconds. I suspect this to be other parameters problem (CONNECT_TIMEOUT or PPPOE_TIMEOUT). Can you please help me with this? Thank you in advance! David
