It seems quite clear from your ifconfig output that your provider doesn't give you a routable address, so you will never see inbound connections. Usually providers have an alternate APN that will give you one, but that depends on the provider in question.Hello, I'm using ppp(8) for many years to connect via UMTS to my service provider and Internet, actually www.fonic.de; all this works fine already for long time, works fine for outgoing TCP and UDP connections to Internet. Until now, I did not care about incoming TCP connections, for example for SSH'ing from remote to my netbook, connected via ppp(8), or for incoming SIP; it turns out now,, that I can: - check with "lynx -dump myip.nl | fgrep WAN" with which addr I show up in Internet: $ lynx -dump myip.nl | fgrep WAN WAN IP adres: 82.113.99.104- can SSH fine to some remote server,- but can not SSH back to the addr 82.113.99.104; I contacted the provider thinking that he is blocking all IP connects which have not been originated by a SYN pkg from my side; but he claims not blocking anything; and now? how can I debug this? My interface looks like this: tun6: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1500 options=80000<LINKSTATE>inet 10.33.28.104 --> 10.64.64.64 netmask 0xffffffff nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>Opened by PID 799 and the routing is: Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 10.64.64.64 UGS 0 1694 tun6 10.33.28.104 link#7 UHS 0 0 lo0 10.64.64.64 link#7 UHS 0 1 tun6 127.0.0.1 link#6 UH 0 75 lo0 Any ideas about this? Thanks. I'm attaching the ppp.conf file. matthias
