I am using git to pull 3.0

[root at v kamailio]# cat .git/config
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = git://git.sip-router.org/sip-router
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
        remote = origin
        merge = refs/heads/master
[branch "kamailio_3.0"]
        remote = origin
        merge = refs/heads/kamailio_3.0


I can't do anything in request route?
[root at v kamailio]# cat /usr/local/etc/kamailio/kamailio.cfg | grep nathelper
loadmodule "nathelper.so"
# ----- nathelper -----
#modparam("nathelper", "rtpproxy_sock", "udp:127.0.0.1:7722")
modparam("nathelper", "rtpproxy_sock", "/var/run/rtpproxy.sock")
modparam("nathelper", "natping_interval", 30)
modparam("nathelper", "ping_nated_only", 1)
modparam("nathelper", "sipping_bflag", 7)
modparam("nathelper", "sipping_from", "sip:pinger at riki.ru")
modparam("registrar|nathelper", "received_avp", "$avp(i:80)")


Maybe wrong with sipping_from address.

[root at v kamailio]# cat /usr/local/etc/kamailio/kamailio.cfg | grep riki.ru
alias=sip.riki.ru:5060
alias=sip.riki.ru:5070
modparam("presence", "server_address", "sip:sip.riki.ru:5060")
modparam("nathelper", "sipping_from", "sip:pinger at riki.ru")

well it is not a server name. but! it is local in database domains, and 
aliased. Changing to pinger at server IP...
