    Hi Rakeshvela

     

    From what you have described, 1.1.1.1 is the Post-NAT IP address for F5 Virtual Server IP address 10.1.1.1 right?

     

    For the question you asked, is 10.1.1.1 same as the self-ip for outbound connections? if yes, then outbound traffic will be initiated from this IP (10.1.1.1). if not, the self-ip for your outbound vlan will be used. Outbound connections to resources where F5 does not have a leg(vlan + self-ip) will be forwarded to your default gateway or next-hop ip address if static routes were set on the box. You will need to add this IP address to your internet accessible subnets in your NAT statement.

     

    HTH Regards Eben.
