3. In the ACL's the following expansion variables are available.
-proxy_host The src IP of the proxy server making the connection
-proxy_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 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.
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
an example, in my connect ACL, I have:
warn condition = ${if and{ {bool{$proxy_session}} \
- {eq{$proxy_host}{}} } }
+ {eq{$proxy_host_address}{}} } }
log_message = Failed required proxy protocol negotiation \
from $sender_host_name [$sender_host_address]
warn condition = ${if and{ {bool{$proxy_session}} \
- {!eq{$proxy_host}{}} } }
+ {!eq{$proxy_host_address}{}} } }
# But don't log health probes from the proxy itself
- condition = ${if eq{$proxy_host}{$sender_host_address} \
+ condition = ${if eq{$proxy_host_address}{$sender_host_address} \
{false}{true}}
log_message = Successfully proxied from $sender_host_name \
[$sender_host_address] through proxy protocol \
- host $proxy_host
+ host $proxy_host_address
