4G - LTE Router

[risco-sam]

Router = TP-Link Archer MR600 / O2 Unlimited Phone/Text/Data Sim

Background:

Contract Started Mid September 2019 (unlimited Sim)

Home Security System (Riscogroup) was connected to cloud until 6th Nov when it went silent. 

Swapped O2 Sim for a Vodaphone sim and it becomes reachable.

O2 Support claim they dont block anything.

Traceroute via O2 doesnt provide any results, vodaphone gives output.

nslookup riscocloud.com

Non-authoritative answer:

Name:    riscocloud.com

Address: 51.105.177.19

traceroute 51.105.177.19

Greatly appreciate any help with identifing where the block is !

It's a problem that has been raised many times before. O2 do block certain ports, even though customer service deny it. 

Your only solution is using a different network.

How wonderful of them - clearly ive not reached the correct person in customer services.

Will be interesting argument in terminating the contract based the evidence.

[risco-sam]

Is there any evidence other than customers like us moaning ?

There's a number of threads on the forum.

The problem with a traceroute is it uses ICMP packets which are now blocked by a lot of networks, so the results arent reliable.

What port is the device trying to connect on? and can you telnet or SSH/RSH to it on that port?

o2 have a clause which means they can protect their network by throttling and port blocking, and bear in mind some ports in the higher end of the range of usable ports are sometimes used by trojans and viruses.

Looking at Risco.com i think a lot of these devices should be using M2M and IOT sims and not a consumer sim meant for a phone.

O2 Tech Support suggested this was not a Data Only Sim being used hence why calls from my alarm system to riscocloud are being blocked - Whats really weird is all other internet traffic is working from 24 Sep - 6 Nov.

Looking at the user manual it suggests port 33000 is used.
