Hi,
I'm new to this so take it easy everyone

Most of my users come from behind a proxy. In order to record the right IP when they register I did the following with register.php (vB 2.2.5, I won't upgrade until 2.3.0 becomes stable ).

Line 450 is the one that actually inserts a new user into the DB. It says:

  $DB_site->query("INSERT INTO user (userid,username,password,email,".$newstylefield."parentemail,coppauser,homepage,icq,ai$

I did this BEFORE that line:

  $ipaddress=iif(getenv("REMOTE_ADDR")!="",getenv("REMOTE_ADDR"),$HTTP_HOST);
  $ipaddress=iif(getenv("HTTP_X_FORWARDED_FOR")!="",getenv("HTTP_X_FORWARDED_FOR"),$ipaddress);

First line will record the regular IP, the second checks if there is a fowarded IP. REMOTE_ADDR might hold the proxy IP not the real IP.

My question is, will this affect $ipaddress somewhere else? Are the two lines safe and will cause a security problem?

Thanks.
Take care,

R.L.
