There is a Cisco router configured by another IT guy with specified addresses from ISP, now the problem is that the ISP give us new net mask and default gateway addresses, so what i did was changing the following addresses
old ISP address -
ip address: 10.131.61.246
net mask: 255.255.255.252
Default : 10.131.61.245
new ISP address -
ip address: 10.131.61.246
net mask: 255.255.240.0
Default : 10.131.48.1
Old Configuration on router
flow monitor MellaFMon
record netflow ipv4 original-input
exporter MellaFEX
cache timeout active 5
