'k, but I want to use the managed aspect of it to be able to hard code the port rates (ie. to fix this full-duplex issue initially) as well as be able to access SNMP so that I can do bandwidth monitoring of external traffic ... I have SNMP setup on the FreeBSD boxes right now so that I can see network load per server, but I want to be able to isolate the 'external' traffic from 'internal', by monitoring the specific port that is connected to the providers switch ... So, in both cases, I need to assign an IP somewhere, correct? ---- Marc G. Fournier Hub.Org Networking Services (http://www.hub.org) Email: scrappy@hub.org Yahoo!: yscrappy ICQ: 7615664
