@Aki,

In the scenario I am, I can surely tell I am s%$#d up. The network setup was done by some fellows and looks something like this:

LAN 1 --> Netscreen <-- 1Mbps --> Netscreen <-- LAN2 --> ISA Firewall ----> Internet

  |                                                                        |

  |                                                                        |

Cisco 1 (acts as GW/DHCP) --> VoIP tunnel --->  Cisco 2 (Another VoIP tunnel to the Internet)

*but is not directly connected to Netscreen*

Within the setup there are 3 Avaya PBXes :-)

It would appear that the Netscreens are the ones causing me grief?? Lan 1 cannot RDP to LAN 2 as well which, according to your statement, seems to be something to do with UDP filtering, right?

This is a network that I feel needs reworking, but for now I just want to figure out the camera issue.

Let me delve deep!
