snatpool <poolname> using automap address
Has anyone else noticed in LTM 10.2.3 when using the snatpool command that the connection sometimes uses the floating selfip instead of one of the snatpool addresses?
My VS has no SNAT setup (But is allowed to SNAT as is the pool) and uses an iRule to set the SNAT for particular client IP addresses.
The snat actually happens and USUALLY uses the snatpool addresses... But every now & again it ises the floating selfip to do the SNAT with... There's no exhaustion of addresses. Usually there's about 200 SNAT's being performed on that poll (peak of 339) with 17 addresses in the pool.
The (very simple) iRule is
when CLIENT_ACCEPTED {
if { [IP::addr [IP::client_addr] equals 172.28.0.0/16] } {
log local0. "SNAT automap [IP::client_addr]"
snatpool isa-selective-snat-eu-pool
}
}
Anybody seen this before?
