Hi Sykurn,

you may apply the iRule below to your IP-Forward VS to flip the SNAT IP selectively...

when CLIENT_ACCEPTED { 
    if { [IP::local_addr] equals "50.50.50.50" } then {
        snat 111.111.111.111

[IP::local_addr]
is the destination address value of the client side connection.

Cheers, Kai
