[OpenSIPS-Users] IPv6 causing problems with HEP in siptrace

Hi Jeff,

That error is generated when the src and dst IP have different AF 
families - which of course is impossible :)

I guess you get the error when you have an incoming SIP packet over IPv6 
(so both SRC and DST should be IPv6), right ?

Best regards,
