Hi Andreas, this is this mean a BTS behind NAT and a OpenBSC +LCR/freeswitch + sip phone on freeswitch will be able to communicate with good RTP ?<div><br></div><div>Rgds</div><div>Nik<br><br><div class="gmail_quote">On Wed, Jan 23, 2013 at 1:11 PM, Andreas Eversberg <span dir="ltr">&lt;<a href="mailto:andreas@eversberg.eu" target="_blank">andreas@eversberg.eu</a>&gt;</span> wrote:<br>

Would the IP.Access nanoBTS works behind a NAT with OpenBSC ?<br>
<br>
i.e. two BTSs in two different locations behind NAT connecting to NITB. im trying to make a call, but it seems rtp has some problem.<br>

hi kelum,<br>
<br>
the NAT firewall should track the RTP frames from BTS behind NAT, so that frames from BSC outside NAT can find their way to the BTS. i suggest to sniff (tcpdump/wireshark) behind and before NAT, in order to localize the problem.<br>
