Hi there
It must work fine. I've just tested it:
kamailio.cfg
xinfo("Checking source IP $si");
secf_check_ip();
xinfo("Result of sec_check_ip: $?");
kamailio.log
Aug 12 16:17:38 pepelux /usr/local/sbin/kamailio[23304]: INFO:
<script>: Checking source IP 85.XXX.YYY.54
Aug 12 16:17:38 pepelux /usr/local/sbin/kamailio[23304]: INFO:
<script>: Result of sec_check_ip: 2
# kamcmd secfilter.print ip
IP Address
==========
[+] Blacklisted
-----------
[+] Whitelisted
-----------
0001 -> 85.XXX.YYY.54
Are you sure that the secf_check_ip() function is executed? Could you put a
log before or after to verify it?
On the other hand, 0 is not a possible return value. If the IP address is
not found, the return value will be 1:

I implemented secfilter in a simple way, in first step routing put that
conditional for black list check that already works:
```
secf_check_ip();
if ($? == -2) {
xlog("L_ALERT", "$rm from $si is blacklisted");
drop();
}
```
BUT NOW i want to change to whitelick checks, so i reviewed the docs and
"2" is resulting for whitelist, so then i said "if not whitelisted so
block" using "!= 2" as on
https://www.kamailio.org/wiki/cookbooks/5.3.x/core#operators BUT SEEMS
DOES NOT WORK: that is the code:
```
secf_check_ip();
if ($? != 2) {
xlog("L_ALERT", "$rm from $si is not in whitelist,
block");
drop();
}
```
when i tested all the calls passed not matter if are in the table or not
as whitelist!
I want able to call only if are present and whitelisted the ip address..
so i also tested with:
```
secf_check_ip();
if ($? == 0) {
xlog("L_ALERT", "$rm from $si is not present, so
block");
drop();
}
```
to check if the ip address are presented in the table but call also passed
and must not cos i not put never a entry in the table!
