Avtech 761 remote viewing

[snoopyuk]

Hi all

Just wondered if you could help me. I have a avtech 761 that i can not see outside my network. I am using a dyndns address that works fine internally but from outside it just shows the avtech software but not the pictures. I have probably missed something simple but cant work out what it is. I am using it with a netgear router on sky broadband. I can also access it using my phone but only from my home wifi network.

could anyone help me please

Thanks Wendy
