[OpenSIPS-Users] nathelper function for ipv6

[Bogdan-Andrei Iancu]

Hi Pasan,

19 is 16 + 2 +1 (as tests) :

/1/- Contact header field is searched for occurrence of RFC1918 / 
RFC6598 addresses.//
/2/- the "received" test is used: address in Via is compared against 
source IP address of signaling//
/16/- test if the source port is different from the port in Via

2 and 16 is checking IP versus IP, so they are not affected by v4 versus v6.

On test 1 I see no checks on v4 or v6 - it simply checks the IP (as raw 
bytes) against the know ipv4 private classes.

Could you try to remove the test 1 (use 18) and see if the test still 
returns true ?

Regards,

Bogdan-Andrei Iancu
