AltocumulusNeed original client IP on SMTP VIP
We have one VIp on port 25 in which we want to allow origin client ip. We asked server team to change the default route that will point to floating self ip of the VIP, that didn't work.
I configured http profile on the VIP and enabled x-forwarder that didn't work too. Kindly provide some solution to fix the problem.
VIP config:
ltm virtual xxxx {
description xxxx
destination x.x.x.x%RD:smtp
ip-protocol tcp
mask xxxx
partition xxxx
persist {
/Common/source_addr {
default yes
}
}
pool xxxx
profiles {
/Common/tcp { }
}
source 0.0.0.0/0
source-address-translation {
type automap
}
translate-address enabled
translate-port enabled
}
F5SJ_I searched some docs in devcentral and prepared one irule.
when CLIENT_ACCEPTED {
set c-addr [IP::client_addr]
log local0. "Client addr: $c-addr"
STREAM::expression {@^EHLO.*@@ @^HELO.*@@}
STREAM::enable
}
when STREAM_MATCHED {
set mstring [STREAM::match]
log local0. "STREAM_MATCHED: string: $mstring"
set replacment [string range $mstring 0 1]
append replacment "LO $c-addr\r\n"
log local0. "STREAM_MATCHED: replacement string: $replacement"
STREAM::replace $replacment
event STREAM_MATCHED disable
}
when SERVER_CONNECTED {
STREAM::disable
}
Will that work?
