WOW! That is really strange! i could not reproduce that. Tested with the
same ip.
but the only possible killer is this code in general_functions:
sub getlastip
{
my ($byte1,$byte2,$byte3,$byte4) = split (/\./,$_[0]);
my $step=$_[1];
for (my $x=$step;$x>=1;$x--){
$byte4--;
if($byte4==0){ $byte4=255;$byte3--;}
if($byte3==0){$byte3=255;$byte2--;}
if ($byte2==0){$byte2=255;$byte1--}
}
return "$byte1.$byte2.$byte3.$byte4";
your Prob seems that the code reduces byte 4, then byte3, then byte2
which leads to this "ip"
But as you can see in my code, i am checking if byte3 is EQUAL 0 and
only then i set byte3 to 255 and reduce byte 2 .. ans so on.
Please check if you have the right general functions !
i appended it to this mail. Maybe i was too dumb to push all code to the
git. it is in my ccd tree...
if you like i will send you the files via mail.

Well also here the same, i can not reproduce that error! It was right,
that this behaviour was when we tested it. but then i fixed that error.
I append the ovpnmain.cgi at this mail. please check it.
