And, you still see the non-healthcheck, normal traffic logged using the X-Forwarded-For information?
Here is my entire config, maybe this will help: # What port do we want to listen on? http_port 80 # Define refresh patterns for content types refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 # Define network ACL's acl all src 0.0.0.0/0.0.0.0 acl localhost src 127.0.0.1/255.255.255.255 acl localnet src 10.0.0.0/8 # RFC 1918 possible internal network acl localnet src 172.16.0.0/12 # RFC 1918 possible internal network acl localnet src 192.168.0.0/16 # RFC 1918 possible internal network acl loadbalancers src 10.26.100.136/255.255.255.255 acl loadbalancers src 10.26.100.137/255.255.255.255 # Define access ACL's.

Yes. Do exactly the same myself with a simple !aclname at the end of access_log directives. I can't figure out why neither that nor the longer log_access is working for you.
