Not sure if anyone can help me on this - I installed a powerlink2 into my visonic powermax pro alarm last night, setup was simple, put a fixed IP address and gateway in and had the GUI up on my laptop in about 10 minutes. Then I want to try the Iphone app out and external access. Got the router port forwarding page up and configured the private fixed IP and private port 443 to external port 443. Tried going out the router and back in from local network and it worked. Then tried to configure the iphone app and connect external via 3g... no luck.. can't connet to server, tried my ipad over 3G using normal browser - no luck, can't connect to server... finally got to work this morning and tried to connect to it over the sneaking wireless which doesn't block any outgoing ports like the main lan.. .still can't connet to server. This is really aggravating as it works perfectly with my CCTV DVR and remote viewing. That is on port 80, the router itself is on port 8081 for https and that works as well, I know my ISP is not blocking any ports incoming. I use dyndns but have tried the IP number as well... I have tried both upnp and without upnp - I don't really trust upnp, but thought I'd give it a go. I'm using a draytek vigor 2800 router and normally it's brilliant at everything, VPN, remote access applications. I just don't get why this one app is not gettiong though. I have also tried forwarding port 443 on the powerlink to various other external ports. The only think I haven't tried yet is forwardiong port 80.. suppose will try that next but anyone else with any experience - would gladly accept any advice.
