You must bridge the MAC addresses across all the router interfaces. There were some postings on this in 1998. Check the archives.

We have successfully testing the network connecting a pc to the HP3000. When the DTC is cirectly connect to the HP3000 via ether-net the DTC's configurations is successfully downloaded. But when we place the DTC on the other side of the network the HP3000 can't find the DTC. If it sounds like I'm rambling I am! What must I do to make the HP3000 see the DTC when the traffic passes thru the routers. -- Larry Barnes Director of MIS Mitek Corp. 4545 E. Baseline Rd. Phoenix, AZ 85040 [log in to unmask]
