Single Private Address to NAT with Multiple Public Address

Hi Team

    Hi

     

    I`ll provide rough guide. you should test and give me result.

     

    creating Virtual server with vlan-enabled INT

     

    Type : Forwarding IP

     

    Source : 1 private IP

     

    Destination : I think this may be 0.0.0.0:0

     

    Using SNAT Pool --> include multifle public IP

     

    My concern is below.

     

    without i-Rule BIGIP didn`t persist SNAT POOL IP. ex) first 192.168.1.100 -> 8.8.8.8:443 | F5 | 10.10.10.10(SNAT POOL) -> 8.8.8.8:443 Second 192.168.1.100 -> 8.8.8.8:443 | F5 | 10.10.10.11(SNAT POOL) -> 8.8.8.8:443

     

    likewise this, when private IP SNAT to external, SNATP IP would be changed likewise LB.

     

    So you have to test first and researching i-Rule persist SNAT IP.

     

    thank you.
