Hello,
I'm used to connect my FreeBSD 10-CURRENT netbook to Internet via PPP;
the provider in question is a German O2 UMTS provider; so far so good,
i.e. all is working as it should: outbound HTTP, SSH, SMTP (I'm just
sending this mail through such a connection), ...
what does not work is VoIP; the call is established via SIP (using a
STUN server), but remote audio RTP packages are not coming down; I
checked this with TCPDUMP: only upstream RTP is send, no incoming UDP;
as well I checked incoming TCP, for example incoming SSH or HTTP; it
seems that incoming UCP/TCP is just not coming through the PPP link;
before bother (complain) the provider with this, I wanted to ask if I
miss something in the PPP configuration to get incoming delivered;
note: I'm not talking about NAT to some stations on a LAN, I just want
get IP to the local host (interface tun6); as well I disabled ipf(8)
which I have configured normaly;
any ideas? thanks in advance
matthias
