![]() When I installed and deployed Forefront 2010 TMG using both Microsoft TechNet: Installing prerequisites for e-mail protection and Microsoft TechNet: Configuring Transport Server having an internal NIC IP 192.168.1.5 and an external NIC IP 98.172.15.152. ![]() I have installed ADLDS, Exchange 2010 Edge Transport Server, and Forefront Protection 2010 for Exchange Server, and Forefront 2010 TMG with all using the RV016 router DMZ port with the Exchange 2010 Edge I am running the Windows Server 2008 R2 Standard Full Version operating system on three servers: a Domain Controller FQDN: (IP 192.168.1.2) on a single machine,Īn Exchange 2010 Server with a full complement (Excluding the Edge Transport Server) of all Exchange Servers on a single machine FQDN: (IP 192.168.1.3), and an Exchange 2010 Edge Transport Server (Workgroup) on a single machineĮ (IP 192.168.1.5). I would like to request that anyone having a similar experience with the Cisco Model RV016 wiredġ6 port router LAN let me know their solution to the problem. I am running Exchange 2010 Server with an Edge Transport Server with a Cisco Model RV016 16 port wired router where with the Subscription enabled, it fails. If your router's NAT settings mandate symmetric NAT, disable it it's behaviour is consistent with the issue you described (though there can be other reasons for it) Ĭheck your phone's STUN setting (page 106 of the user manual) and enable it STUN works great behind NAT when it comes down to traversing your local network by informing the remote party on sending its audio to an working port. If your router supports ALG and it is enabled, you should attempt reversing this setting as it effectively tampers with the SIP flow through your router its purpose has been obsoleted by NAT and these days it does more damage than help ![]() The reinvite is rejected by the other party on the account of the SDP being bogus (rightfully so), and during the course of the capture, this series of events repeats several times. Moreover, about a second into the call, your phone is sending a reinvite, this time using its local IP address rather than a publicly routable address: The issue is that while your phone successfully sends out its audio, it is not receiving any in return. Here is the rationale behind it: the capture you posted shows the remote party expecting media on port 33880 whereas your phone expects it on port 5012. You should check your router's NAT or ALG settings as well as the STUN settings of the phone. I have no idea why this is in the log.ġ0.1.0.4 is my internal IP for the phone.ĭoes anybody have an idea what could be wrong? I've change the phone numbers in the log.ġ11122223333 is the landline I was calling.Ĥ44455556666 is my mobile number I was calling from.ħ77788889999 is also in the log which is another configured landline. Unfortunately I have no experience with SIP so far so from the log I can't really tell if everything is correct there. It does not really look like a problem of a closed port or something else with the firewall. But: When I hang up on one side, the other side get's notified. In the opposite direction I also can't hear anything but the connection stays open. After 10 seconds the connection gets closed. The issue is that it is ringing, I pick up, but can't hear anything. Please have a look on the tcpdump I took while doing a call from my mobile to my configured landline: On the edgerouter I've whitelisted and forwarded almost every port to my phone (10.1.0.4). Those settings should be correct according to Telekom support. ![]() Only configuration I did there is following the wizard, entering my phone number and selecting predefined Telekom settings. Internet works well but I can't get VoIP working. I'm using ubiquiti edgerouter x with an pppoe connection to Telekom. I'm from germany and my provider is Deutsche Telekom. Set description "Inbound traffic to WEB GUI" If you require access to the Web GUI from an external location, you will need to create a firewall rule to allow the traffic.Ĭreate the firewall rule to allow inbound traffic on port 8443 edit firewall name WAN_LOCAL rule 50 Set the Web UI port change 8443 to whatever you would like To expose the EdgeRouter from the WAN, using an alternate port, I think you need to first change the web gui port. With VPN, you'll also want to install a valid cert. Otherwise you're at risk of a man-in-the-middle attack, because the self-signed cert that ships with the EdgeRouter is public domain. If you go with the solution you're suggesting, I'd highly recommend that you also replace the HTTPS cert with a valid cert, that has been signed by a root CA. However, what you're asking can still be done. I agree that VPN is a more secure solution.
