Something that acts like an arp proxy on your end might do the trick. chris kleban -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Miguel Mata-Cardona Sent: Thursday, February 15, 2001 1:19 PM To: nanog@merit.edu Subject: cablemodems and voip Hi, I've been following this list quite a while, I'm a little off topic but in the need of serious help. You can mail me direct all your help and I'll post a summary at the end. thanks in advance. ----------------------------------------------- problem: We are a cablemodem provider and have disabled the peer to peer options in our CMTSs to avoid problems with NBT and directed broadcast to our customers. The network has been split in many nodes around the city and each node is as follows: to other nodes | | ------------- | router | | 10.2.15.1 | ------------- | | --------------- | cable modem | | termination | | system | --------------- /\ / \ / \ / \ me other 10.2.15.2 10.2.15.3 As you might guess, under this configuration "me" and "other" won't be able to ping to each other. We have done some tests with linux setting "route -net 10.2.15.0 netmask 255.255.255.0 gw 10.2.15.1" and it works but it does not on win9x. We are looking for this solution because we are deploying a VoIP to some customers on the same node. The above solution, if possible under win9x, would bring a problem because we are modifying the customer machine instead of our network but is feasible solution anyway. Is there a way on doing this within our nodes? if not, is there a way to modify or tweak the win9x routing table? -------------------------- Miguel Mata-Cardona CCI El Salvador mmata@sv.cciglobal.net
