The X-lite client is installed behind an ADSL router and it seems the ISP also has a firewall supposedly protecting their ADSL customers blocking some netbios ports and non-critical. I can't make outbound calls but I can receive but before then I had to use the following in the account section in SIP.conf [2222] ... type=friend secret=xxxx host=dynamic ;dtmfmode=inband ;

Hello, All I'm looking for is a yes/no answer here. I have heard that the following scenario is possible (reasonably easy to implement as well) . but I just don't get it :-) . if it is possible I'll go ahead and learn on my own, I just don't want to waste time on something that will not work. Scenario: 2x VoIP phones - Each phone is configured to register

Hi there, I've got a question about the fact that the source port of an outbound packet may not be altered by a masquerading firewall. Unfortunately the example on the website does not explain why this has to be done. Forwarding an inbound packet is often needed but WHY has the source port to remain unchanged? I'm not a too good coder so it's hard for me to reproduce what happens. Is

We have about 300 users distributed on different vlans using private ip network spaces, and sharing one single public IP when going out to the Internet. Our samba (3.0.24) server has a pulbic IP and is running as a primary domain controller. All clients receive Sambas's public IP as their WINS server. I am able to join the domain but samba stops responding sporadically. Looking at the

I know this is not a normal request, but I would like to connect two vlans into the same box that have the same subnet on them, and then NAT them out to the Internet. We don''t need to make any connections inbound to them, but only provide outbound access. Any suggestions on how to do this? If I can''t do it with routing then I could use something like user-mode Linux, or other
