Dear senthil
As i have suggested u earlier
taking primary route for lease line
use command
ip nat inside source list 101 interface serial0 overload
delete loopback interface
secondly in bri0 config ip address is negotiated so check what ip address u r getting . try to ping an internet ip drom ur router when isdn is active
if it works then
just prepare access list 102 permitting same internal network and overload it with bri0
problem u r facing can happen if isp failed to put seconary route pointing bri0 .u can check this through as u have put this command
ip nat inside source static 192.168.5.20 59.145.X.X extendable.
just ask any 1 of them to ping this ip 59.145.X.X from outside . when lease line is down . if it's doesnt ping that means isp had not inject secondary route for same network 59.145.a.b/29 will be i guess. ok try this and let me know
