openser is doing reverse DNS lookups? I do not understand why. avp_check uses a regular expression, comparing the string in $dd with the pattern 192...... AFAIK openser does not care if these strings are domains, IP addresses or anything else

Hi Everybody,

I have a question regarding avp_check() and reverse-DNS-Lookups: I wanted to do the following in the routing logic (simplified):

loose_route(); if (avp_check("$dd","re/192.168.123.(1|2)/g")) {

The idea was to allow flexible re-routing to another proxy in case of loose-routing. One proxy would be the alias of the other, and so far, everything was fine. What happened now: We had a customer, who's IP could not be "reverse-lookuped" properly, the DNS-Server ran into an timeout. After we removed the code-snipplet from the routing, everything was fine (again); except this functionality drawback.

I believe, in OpenSER 1.2 i could replace it with the following, to avoid the reverse-lookups:

if (($dd == 192.168.123.1) || ($dd == 192.168.123.2)) {

Am i right? Would this work?

Can i somehow avoid the reverse-lookup in OpenSER 1.1?

Thank you everybody,

Carsten
