When using the POP3 proxy I'm getting alerts on the rule for "BAD-TRAFFIC same SRC/DST" SID=527.
This is my config for POP3 Proxy DNAT rules etc.
I host my mail server in a DMZ off of ASL and ASL is behind a router.
The router forwards ports (110 is among them) to the external interface of my ASL machine.
I have a DNAT rule:
SRC=Any, DST=external_IP SVC=POP3
Change SRC=No CHange
Change DST=Mailserver
Change SVC=No CHange
POP3 Proxy has one proxied network defined "SRC = Any, DST=External IP"
If I set it to proxy "SRC=Any, DST=Mailserver" it fails.
The proxy works fine but alerts on SID=527. Is my config messed up?
