hi klaus,
first, thx for helping out.
i am running the "ser-0.8.12-0.i386.rpm" version of SER on redhat 9 released
by iptel.org
i am a newbie in linux.... so if u could instruct me on how to locate the
nathelper module then perhaps i can find out the more about the version in
detail.
best regards,

which version of ser do you use? It's for sure in unstable and stable
from cvs.

hi, when ever i startup SER with this function used,
"nat_uac_test", i get
the cfg loading error "is some module missing"
i know the function is in nathelper module, and it is loaded too.
can someone tell me what to do in order to use this function?
below is a sample code using nat_uac_test. thx in advance.
marty.
==============================================================
if (nat_uac_test("3")) {
# allow RR-ed requests, as these may indicate that
# a NAT-enabled proxy takes care of it; unless it is
# a REGISTER
if (method == "REGISTER" || ! search("?Record-Route:")) {
log("LOG: Someone trying to register from private IP,
rewriting\n");
# This will work only for user agents that
support symmetric
# communication. We tested quite many of them and majority is
# smart smart enough to be symmetric. In some phones, like
# it takes a configuration option. With Cisco 7960, it is
# called NAT_Enable=Yes, with kphone it is called
# "symmetric media" and "symmetric signaling". (The latter
# not part of public released yet.)
fix_nated_contact(); # Rewrite contact with source IP of
signalling
if (method == "INVITE") {
fix_nated_sdp("1"); # Add direction=active to SDP
};
force_rport(); # Add rport parameter to topmost Via
setflag(6); # Mark as NATed
};
};
