Re: [Serusers] checking source ip and dest ip

In fact, I am not looking for "if address is NATed or not", I need to check if address belongs to my network or not. what do you mean by RFC1918 addresses ?

That's what the onsip.org nat-handling scripts do. A NATed destination is determined by a flag in the location record and the src ip is checked with nat_uac_test(). It will give a more robust NAT handling that testing on IP addresses for parts of the RFC1918 addresses. The problem has already been solved, why not reuse? ;-) g-) İlker Aktuna (Koç.net) wrote: > Hi, > > I need to check source ip of a SIP message and also destination IP to > which the message will be sent. > i.e. I will use mediaproxy only if the one of the ip addresses match > 10.0.0.0 / 255.0.0.0 > > is it possible ? > > Thanks, > ilker > C "-//W3C//DTD HTML 4.0 Transitional//EN"> > In fact, I am not looking for "if address is NATed or not", I need to > check if address belongs to my network or not. > > what do you mean by RFC1918 addresses ? > > Thanks, > ilker > > ------------------------------------------------------------------------ > *From:* Greger V.
