I have central router where ISP1 is connected.
router WAN side ip=203.109.128.x/30
and LAN has real IP 203.109.127.x/28
so in my server (DNS, Mail,proxy) has real ip which given by ISP1.
my default route to ISP1
Now another ISP2 is connected in my central router , my aim is when ISP1 is down all traffic goes to ISP2.
ISP2 Ip is 112.123.12.X/30
For test purpose I am redirect route to ISP2. default route 0 0 ISP2.
My server IP segment is unchanged. now when I ping from my server to yahoo.com its ok. but when I am start browsing from my server, browsing is not ok. but that time when I am again defaut route move to ISP1 then browse is ok.
So its poroblem that LAN real IP another ISP and goes to different ISP ??
so I need to route 203.109.127.x/28 in ISP2 ???
