Hi everyone: Because I couldn't find the RPM package SER-0.8.14 for linux, and the mysql supported package. I have installed SER-0.8.12. But there is no "ping_nated_only" and "nat_uac_test" in module nathelper . To judge whether the client is behind NAT, How can I do? Anyone help me please! thank you!
