maw246 Posted October 11, 2015 Share Posted October 11, 2015 I have a L2TP VPN set up on my network firewall that allows access to the entire network from outside. The Control4 app on my phone appears to time out when I try to use it from outside. The Lutron app works fine for my RadioRA2 switches so I know I am getting to network. I can ping the HC-800 IP address and it responds. Am I missing something or has Control4 done something to lock this down? Quote Link to comment Share on other sites More sharing options...
alanchow Posted October 11, 2015 Share Posted October 11, 2015 It should work. I would see if you have allowed for layer 2 broadcasts setup on your VPN. Quote Link to comment Share on other sites More sharing options...
C4RVA Posted October 11, 2015 Share Posted October 11, 2015 You can also just enter the IP address of the controller in the c4 app. Matt Lowe 1 Quote Link to comment Share on other sites More sharing options...
maw246 Posted October 12, 2015 Author Share Posted October 12, 2015 Thanks to both. To be clear, the Control4 app works fine when I'm on the network and IP address is entered. Not sure how to check Layer 2 broadcasts are set up in VPN. Quote Link to comment Share on other sites More sharing options...

C4RVA Posted October 12, 2015 Share Posted October 12, 2015 If you're able to ping the controller you should be able to connect. What version of c4 are you on? Quote Link to comment Share on other sites More sharing options...
C4RVA Posted October 12, 2015 Share Posted October 12, 2015 Do you have an IP address entered on this screen? Quote Link to comment Share on other sites More sharing options...
maw246 Posted October 12, 2015 Author Share Posted October 12, 2015 Do you have an IP address entered on this screen? If you're able to ping the controller you should be able to connect. What version of c4 are you on? I have a slightly different screen (includes account info) and Advanced Security is not something that can be selected, but IP address is shown and it can be pinged. Again, I have no problem if I am on the LAN with the App only when I tunnel in with L2TP VPN from outside the LAN. Quote Link to comment Share on other sites More sharing options...

zaphod Posted October 12, 2015 Share Posted October 12, 2015 Are you trying to connect when your phone has a wifi internet connection or a 3G/LTE connection? I have had problems using the C4 app via VPN in the past when my phone/iPad was only on LTE. So I put my iPad on wifi hotspot and connected my phone to the iPad and then it would work. It seems like the app was looking for a wifi connection before letting you connect to a controller - this was a year or so but it may have been fixed by now. Here is that thread - maybe there is something there that helps. http://www.c4forums.com/topic/14682-unable-to-connect-to-myhome-over-vpn/ Quote Link to comment Share on other sites More sharing options...
maw246 Posted October 13, 2015 Author Share Posted October 13, 2015 Thanks for the lead. I am trying to do this over LTE because if I access the VPN while I'm on my local network it behaves like there is not VPN. I can't try this until I get to another network. I did have my daughter try this from her network and it did not work. Will look at the post. Quote Link to comment Share on other sites More sharing options...

If you edit the IP address in the Control 4 app and change it back it works over LTE. I'm on 2.7.2 so C4 has not fixed this bug or they want to sell 4sight licenses. So this is not a VPN issue at all. Thanks again for the lead Quote Link to comment Share on other sites More sharing options...
ILoveC4 Posted October 13, 2015 Share Posted October 13, 2015 I connect to VPN over cellular all the time without issue, up until this past Friday. I tried to connect via cellular VPN and it was telling me I needed a valid user license. I didn't think to try this trick. I know the VPN was working because I could access my surveillance system. I didn't think to try this trick. I'll try it now. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
ILoveC4 Posted October 13, 2015 Share Posted October 13, 2015 For anyone else that might get the same message I was getting (screenshot attached), changing the IP to address to something wrong, saving it, trying to connect and then changing it back to the correct IP worked for me as well. I too am on the latest OS release. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

AP-123 Posted October 17, 2015 Share Posted October 17, 2015 I can connect from outside using VPN only from wifi. If I'm using my cellular network I can't connect. Sent from my SM-N920V using Tapatalk Quote Link to comment Share on other sites More sharing options...
Matt Lowe Posted October 17, 2015 Share Posted October 17, 2015 there is an issue with the app looking to connect to the controller over cellular if you do not have remote access. The current resolution is to go into the settings delete the ip address try to connect with it empty then reconnect using the local ip address of your controller.

RobG Posted October 25, 2015 Share Posted October 25, 2015 Has there been any solution to trying to connect over LTE? Still getting the "Unable to Connect .... 403.21) error. Quote Link to comment Share on other sites More sharing options...
maw246 Posted October 25, 2015 Author Share Posted October 25, 2015 Has there been any solution to trying to connect over LTE? Still getting the "Unable to Connect .... 403.21) error.I corrected the problem on LTE by opening the C4 app, changing the IP address to a bad address, trying to connect (which fails), then changing the IP address back and connecting. This worked for me. Again see the thread as follows: http://www.c4forums.com/topic/14682-unable-to-connect-to-myhome-over-vpn/ Quote Link to comment Share on other sites More sharing options...
Viperman Posted October 26, 2015 Share Posted October 26, 2015 just because you can ping it doesn't mean it will work. Ping uses the ICMP protocol. Not sure what connecting to the control 4 uses. I would think HTTPS but I could be WAY wrong. You could throw a sniffer on the wire and check. Verify those ports are open or use netstat or some other tools to check it.
