Using new pool of IPs website is unreachable

Hi All,

 

We have F5 acting as an link load balancer and authoritative DNS wherein all requests are resolved from F5 DNS which is at the perimeter of organisation. When requests arrives at F5, it is natted to back-end firewall which is then natted to back-end server. Right now the issue is we have got existing three links terminated on F5 from which one of ISP link provider has allotted new pool of IPs, we have used that new IPs to create wide IP for a website and which is then also natted to firewall IP. Wide IP are getting resolved and we checked statistics as well, but request is not passed to back-end firewall which is then natted to back-end server. Also VIP has been created with new IP and pool member is the natted Firewall IP. Can anyone help me with this issue?

 

Thanks in advance!!!
