I have a single port Dynalink RTA1320 DSL router going to a four port ZyXEL P334W WiFi access point/router. The Dynalink is handling DHCP, firewall and port forwarding. Currently the ZyXEL has only my iMac connected via ethernet. WiFi is used for my NDS - not currently on. WiFi is 802.11b secured with WEP and allowing only the NDS's MAC address. Yeah, that can be broken and spoofed respectively, but I'd see the activity (visually via the WLAN light), not to mention I'd have trouble connecting my NDS - and I never have. The only oddity is I could never could get the ZyXEL's WAN port to work without a phone call to their support (they helped set it up in the past, but I can't be bothered again - it's an international call). There's something iffy I obviously always overlook there. So I just have the Dynalink modem plugged into one of the ZyXEL's four LAN ports which works. -- If you're not part of the solution, you're part of the precipitate.

I've DHCP turned OFF on my ZyXEL switch. On my Dynalink modem I've reserved 192.168.1.2 via MAC address for my iMac. In case you've not read the other post - my network right now is very simply a single port Dynalink RTA1320 DSL router going to a four port ZyXEL P334W WiFi access point/router. The Dynalink is handling DHCP, firewall and port forwarding. Currently the ZyXEL has only my iMac connected via ethernet. WiFi is used for my NDS - not currently on. -- If you're not part of the solution, you're part of the precipitate.

These are maybe from running VMware? If you turn off VMware, then does en1 become your only interface with an IP address assigned? And if so, can you name your computer as you wish (using system preferences) in that case?

The last interface listed, vmnet1, is an Ethernet interface from VMware Fusion. It's using the same name. So to solve the issue, go into VMware Fusion, start Windows if needed, right-click My Computer and choose Properties, and change the computer name to something other than Crystalis. -- Send responses to the relevant news group rather than email to me.

Ah huh! I thought Fusion would have to be running. TY JR, I'll try it right away. -- If you're not part of the solution, you're part of the precipitate. |
