• pfsense CARP - wan failure on firewall

  - by eldblz

  I have recently configured 2 firewall (on 2 DELL PowerEdge R210II with ESXI 5.1) with pfsense. We have several LANs and 2 WANs. Everything is running fine but i have a strange behavior: i can access internet from alla LANs but not from the firewall (itself). For example the firewall cannot retrive package information or if i setup a gatway monitor ip (like google 8.8.8.8 ) this fails. These are the screenshots of firewall configuration: http://imgur.com/a/LNuMz#0 ATM i kept firewall rules to minimum to avoid problem or conflicts. Any ideas how to solve the problem? Thank you in advance.

• Programming logic best practice - redundant checks

  - by eldblz

  I'm creating a large PHP project and I've a trivial doubt about how to proceed. Assume we got a class books, in this class I've the method ReturnInfo: function ReturnInfo($id) { if( is_numeric($id) ) { $query = "SELECT * FROM books WHERE id='" . $id . "' LIMIT 1;"; if( $row = $this->DBDrive->ExecuteQuery($query, $FetchResults=TRUE) ) { return $row; } else { return FALSE; } } else { throw new Exception('Books - ReturnInfo - id not valid.'); } } Then i have another method PrintInfo function PrintInfo($id) { print_r( $this->ReturnInfo($id) ); } Obviously the code sample are just for example and not actual production code. In the second method should I check (again) if id is numeric ? Or can I skip it because is already taken care in the first method and if it's not an exception will be thrown? Till now I always wrote code with redundant checks (no matter if already checked elsewhere i'll check it also here) Is there a best practice? Is just common sense? Thank you in advance for your kind replies.
