Two solutions: your existing asterisk server could be given an interface on the internal network (without forwarding packets). Second, you could deploy an additional internal Asterisk server whose sole purpose would be to translate SIP calls to IAX, to relay to the outside Asterisk server. -Tilghman ___ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users

All my SIP devices in my home network are behind the NAT. The asterisk server at our institute has a official public IP address. Maybe the existing firewall ca make some trouble ??

Re: [Asterisk-Users] SIP, NAT & Asterisk
Hi all, beacause I am a newbie in the asterisk ralm and the existing documentation could not satisfy I'd like to ask you some Questions: 1. Does somewhere in the Internet exist additional documentations for asterisk configuration ? http://www.digium.com/handbook-draft.pdf In addition, there are a variety of home-built pages. http://www.automated.it/guidetoasterisk.htm http://asterisk.gnuinter.net/ 2. Does Asterisk work as a standard SIP Proxy ? No. Asterisk can perform basic SIP redirection, but it is not a standard SIP proxy in many of the ways that you might expect. It can do _some_ of the features of a SIP proxy, but to call it a SIP proxy would be an overstatement. 3. I am just installing a Asterisk PBX in our institute and additionally I purchased some ot the Snom 100 SIP devices. For SIP account I have registered with iptel.org and fwd.pulver.com. Both work fine with the Snom 100 device. I tried the Snom 100 from home via a Linksys DSL router wich supports UPnp and port range forwarding to the private network. I faced some troubles with registering the Snom with IPTEL.ORG from my NAT'ed network. Because I'd like to setup a Asterisk PBX to my private Network as well my approach is to connect the SNOM to the asterisk at home network and establish a server-server connection via IAX to the institutes Asterisk server. The institute's Asterisk can login at iptel.org and fwd.pulver.com. If soembody wants to call me he should first try to reach me at my Snom phone at institutes premisses and after a defined time this call should be forwarded to my home asterisk server to reach the SNom 100 at home. BTW - for calling out I want to use the AVM Fritz ISDN card with ISDN4LINUX. I could not find any doc for Asterisk- ISDN4LINUX configuration. Later I'd like to upgrade to a Digium device to support conferencing. Wich of the Digium's devices you propose for a normal EuroISDN line (2 B-channels) ? I have attached a small figure for my SIP configuration aaproach. My suggestion is that if your Asterisk server is behind a NAT, the only hosts it should talk with are devices that are also behind the NAT, or other Asterisk servers via IAX or IAX2 which may be on the outside of the NAT. Anything else causes more headaches than it's worth. I'm afraid I have no experience with the EuroISDN equipment, so I am not qualified to answer that part of your questions.
