Here is my setup: * is on a NAT'd subnet, but also has an externally routable IP address. I have a Snom360 that's external to this and behind NAT. The Snom360 can call other phones in * subnet (by their internal extension numbers) and voice is transmitted fine; however, when I attempt to check voicemail (or any * voice...

Hey all, quick question: I have a server running Samba 2.2.3a which has two NAT'd private domains behind it (192.168.1.0/24 and 192.168.88.0/24). The .88.0 subdomain has a wireless AP/router on it (192.168.88.254) which also does NAT (the wireless machines are on 192.168.92.0/24). The router has the IP of the second internal NIC as its gateway; the wireless machines...

All, I have my * box NAT'd with all ports forwarded that are SIP related (based on Wiki). I also have nat=yes, externalip=WAN address of firewall, internalip=LAN network of *. I have my Xten soft phone on a PC which is NAT'd behind firewall with ports forwarded. I have also followed instructions on Wiki for Xten...

I am trying to make 1 soft SIP UA behind NAT connect to a public hard CISCO UA via a public asterisk server. The CISCO UA can hear the voice from the SIP UA but not vice versa. I do set nat to yes for the soft phone. Any help would be greatly appreciated. Below is my sip.conf [general] port = 8060 ; Port to bind to (SIP is 50...

For anyone who is interested, I have a working tftpd (modified wvtftpd) capable of serving configuration, dialplans, and ringtones to Cisco 7960/7940 and ATA-186 devices that are located behind NAT firewalls. As TFTP is not a very firewall/NAT friendly protocol, I had to break some rules to get it to work with these cisco devices. It might cause problems for other TFTP clients, but it works with the cisco's which I needed.. Your tftp server can also be located behind a NAT or firewall if...

Greetings- I recall mention of this bug at some tim elast year, but do not know if anything yet has been done to address it or if it is in any plans... I have multiple servers behind a f/w. I have ports forwarded on the f/w which map to port 22 on the various servers. i.e. ssh -p1001 FIREWALL_IP ---> NON_ROUTEABLE:22 This is fine, but the hostkey negotiation obviously fails... Is

Hi, I have the following setup: Asterisk <-> Nat <-> Internet <-> Nat <-> 2 x SIP endpoints With directmedia=no I can make a call between the two SIP endpoints; the RTP stream being passed through the Asterisk box. Obviously, this is sub-optimal. I attempted to enable bridging of the call between the 2 endpoints directly, give...

Hi all, Love tinc by the way. It's a great VPN. I'm having issues with 2 nodes always talking through an intermediate node. My set up is a VPS in a cloud somewhere that's running tinc and 2 other nodes - one a roaming laptop (always NAT'd) and the other a server behind a dynamic IP home broadband connection (Not NAT'd but firewalled). Neither the laptop nor the home server have any firewall rules that accept incoming traffic for tinc. They can all talk to each other, but it always routes the traffic via the VPS which...

...'m trying to do: I need to setup the PBX to answer on multiple 'lines' (I use that word with trepidation as I'm not sure if it's the right term in the absence of modems & actual lines) and play a brief message identifying itself as the 'line' connected to. The originator of that call will be a softphone. Before rolling this out to my lab, I'm trying to work out the proper config on my laptop. Therein I have Windows XP w/ VMware - Red Hat 7.3 is running in a VMware session. My connection to the net is NAT'd. My internal IPs for both XP & Linux are...

System = CentOS / Apache 2.0 / HTML files location = /var/www/html Nat'd IP - ports 80, 20, 21 already opened & routed to internal ip. I desperately need the quick & dirty solution. I need a setup where one user can ftp from another desktop (windows) to upload new website files. I currently have CuteFTP, but will use anything needed at this point. I nee...

I have 20-30 GXP2000's connected to * over a T1 line. Neither end is NAT'd and there is plenty of bandwidth available over the line. The GXP's are 1.1.5.15, which is the latest. I have a problem where the phones keep dropping off of * and I get a "failed to register" message in the log of *. Sometimes they eventually connect and sometimes, I hav...

Good Day All I recently implemnetd asterisk outside our LAN (external network).It works well in a NAT settings. But on external network with PROXY setting ASTERISK DID NOT WORK. My question are 1 Can ASTERISK work in a PROXY setting . 2 If it can work how can i implement it . Expecting your reply Thanks Paul --------------------------------- Yahoo! Messenger with...

...ingle port. (!) Sometimes it's a web service, sometimes it's a VNC service. Here's what I had in mind: 1) Server is normally a webserver listening on port 80, and normally has the following rules active: # iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # iptables -t nat -A POSTROUTING -j MASQUERADE 2) Server hosts a special PHP script, that when called correctly, sets rules like # iptables -I PREROUTING -p tcp -s $REMOTE --dport 80 -j DNAT --to-destination $FWIP:$FWPORT # iptables -I FORWARD -p tcp -s $REMOTE --dport 80 -j ACCEPT The *next* tcp connection f...

We have a handful of nodes set up. Some are NAT'd but a few have direct access to the Internet. Sample confs: HostA: Name = HostA AddressFamily = any Interface = tap0 Mode = switch Connectto = HostB GraphDumpFile = /tmp/mesh HostB: Name = HostB AddressFamily = any Interface = tap0 Mode = switch Connectto = HostA GraphDumpFile = /tmp/mesh...

Yes, our spectrometers that run VNMRJ are not allowed directly on the network. They are tucked away safely behind a NAT'd firewall with very few ports open and access is only allowed by proxy ssh from a few IP addresses (for some reason the users want to retrieve their data from it!). The extra cost of a firewall is nothing compared to the cost of the instrument. P.

...ernet. I've got the device on the VPN and it participates nicely, but I can't talk to the internet at large. When I tcpdump the external interface on the exit node, I see the packets leaving the network, but the source IP is still the tinc VPN IP address of the device, and it's not NAT'd the source as I expected. I've checked that I've added an iptables rule to do this, but for some reason it's not hitting it. I'm not new to setting up NAT gateways with iptables so I'm pretty sure that bit is correct. Could this be something to do with it coming from...

...OSTNAME will be a problem as a web server. Currently I have loaded a html doc in - /var/www/html, but I had to load from cd directly on this machine. Is is neccessary to setup ftp to be able to upload html from remote system? Don't know if this is important at this point - but this system is NAT'd to an internal ip. Heck of a 1st Linux project, huh. That's for all the advice. Beth -------------- next part -------------- An HTML attachment was scrubbed...

I have found that the NTP server is not contacted when the phone (Budgetone 100) comes back from a power down. I must reboot the phone without powering down to get the phone to contact the NTP server for the time. It doesn't matter whether I reboot from the phone's web site or using the menu reset function: either works. I have only tested this with a private NTP server. This may

I'm having a problem configuring asterisk to send incoming calls to Firefly. I can make outgoing calls from firefly through asterisk without any problems at all. The firefly client does this when it's on the same IP subnet without a firewall, or from a NAT'd environment. Can anyone tell me where I'm going wrong?
