Ports or service type blocking - CCTV

[Anonymous]

Hi, I'm trying to connect to my office CCTV which uses two tcp ports - 5290 for commands and 5291 for streaming. My iphone app (MViewer) can connect fine using a local IP addresses over the local LAN/WiFi, but if I try to access the CCTV DVR box from O2's mobile network it simpy cannot connect.

I know my ADSL router is set up OK (work with this stuff all day) and can happily get access from external networks using WiFi on my phone, but as soon as I disable WiFi and rely on the O2 GPRS/3G system, I get no access.

I did try to sort this out months ago (while still locked in a contract), but gave up as the frontline support staff simply hadn't a clue what I was talking about. A mate, who has the same setup but on Vodaphone gets access no problem, so i can only summise that O2 is restricting based on port or traffic content.

Anyone here who knows what O2's policy is as I'm out of contract now so would like to fix this one way or the other.

@macblank,

I'm afraid perksie is right. This is a matter for the O2 technical staff themselves to answer. Whilst I myself have never had any issues with protocol/port blocking on O2, I have no idea and no way of telling what filtering techniques they use on their web-facing gateway for us.. I think only those who are directly involved in this business would have those details.

I did actually suggest the TECH TEAM

They are not the quickest in getting back to u, but they will

The Internet is rather silent about the operation of their operating technique:/

You did indeed, but as a rule the technical department at O2 (the grunts that make sure the right lights are showing on the right boxes) don't talk to customers. They prefer to advise the customer care team on what to say and pass it down from on high.

Can't say I blame them, having worked in IT support myself!

Highly unlikely, that would set a precedent as it's never happened before.

It is rare but not the 1st time.

I had an issue yrs ago n spoke direct to the tech team.

They did have a system set up for tech support on a pay per fix basis, but they scrapped it.

I finally got fed up - switched to Vodafone - Can now stream H264 from my CCTV systems to my phone without any difficulty. 

O2 are clearly only setup to support the most basic of issues, and are utterly useless at dealing with business customers.

I had the same issue, with O2. You have two options, first you can run any free VPN from your phone, this will bypass any port blocking O2 use. Second option is if you change the ports on the CCTV system, and then again open these on the router to something else (as not all ports are blocked) 

O2 were no help with this issue, I had to work it out myself.
