PHP warning foreach in vpn_ipsec_phase1.php

[reetp]

Another one

PHP Warning: Invalid argument supplied for foreach() in /usr/local/www/vpn_ipsec_phase1.php on line 775

No check for a set variable - this warning was logged even though I only used PSK

I presume this is because I have no certificates setup.

755

Again a quick "isset" should be used somewhere

should be fixed with 9fe1b63
