I am relatively inexperienced with Cisco routing, so this is probably a simple question. Here's the hardware: Location A Cisco 2621 Router IOS 12.0 Interfaces - e0 to local LAN 192.168.48.55/24 s0/0.100-s0/0.105 to WAN (IP 192.168.100.1/24 - 192.168.106.1/24) Locations B-H Cisco 1720 or 1750 IOS 12.0 Interfaces - e0 to local LANs on each router 192.169.41.55/24- 192.168.47.55/24) s0/0.1 to WAN on each router (IP 192.168.100.2/24 - 192.168.106.2/24) This network is running 3DES on frame relay. Here's the problem: I am attempting to use a PC remote control software package (NetSupport) to control PCs on the network. The software resides at location A above. I am unable to see the PCs on the subnets at locations B thru H with the NetSupport software when browsing, but can see them using the client's IP address. NetSupport looks at the network broadcast address to find available clients. My thinking is that an ip helper-address command is needed for each subnet B-H on the router at location A. Also, I would need to use the ip forward-protocol 5405 command as the software uses udp port 5405 to talk to the clients. My questions: First, is my thinking correct on using the ip helper-address/ip forward-protocol commands? Next, would I use the ip helper-address command on e0 at location A? or another interface? Am I missing something else? As a test, I have tried using ip helper-address 192.168.41.255 and 192.168.42.255 on e0 at location A in conjunction with ip forward-protocol 5405 with no success. Can anyone help? -Phil __________________________________________ If replying by e-mail, replace the nospam with an underscore character
