Exim version 4.82
-----------------
3. In the ACL's the following expansion variables are available.
-proxy_host_address The src IP of the proxy server making the connection
-proxy_host_port The src port the proxy server is using
-proxy_session Boolean, yes/no, the connected host is required to use
- Proxy Protocol.
+proxy_host_address The (internal) src IP of the proxy server
+ making the connection to the Exim server.
+proxy_host_port The (internal) src port the proxy server is
+ using to connect to the Exim server.
+proxy_target_address The dest (public) IP of the remote host to
+ the proxy server.
+proxy_target_port The dest port the remote host is using to
+ connect to the proxy server.
+proxy_session Boolean, yes/no, the connected host is required
+ to use Proxy Protocol.
There is no expansion for a failed proxy session, however you can detect
it by checking if $proxy_session is true but $proxy_host is empty. As
[$sender_host_address] through proxy protocol \
host $proxy_host_address
+ # Possibly more clear
+ warn logwrite = Remote Source Address: $sender_host_address:$sender_host_port
+ logwrite = Proxy Target Address: $proxy_target_address:$proxy_target_port
+ logwrite = Proxy Internal Address: $proxy_host_address:$proxy_host_port
+ logwrite = Internal Server Address: $received_ip_address:$received_port
+
+
4. Runtime issues to be aware of:
- Since the real connections are all coming from your proxy, and the
per host connection tracking is done before Proxy Protocol is
# appropriate links, and then creating and running the main makefile in that
