Huh? A hub has >ZERO< MAC addresses. It's a simple line that all of the devices which DO have a MAC address (i.e., a NIC, a WAN port on a router, etc.) connect to. It's literally just and electrical wire, with some minimal smarts. Even a SWITCH does not have a MAC, >UNLESS< it's a managed switch. Now, a ROUTER would have a MAC address, especially if it's doing NAT and MASQuerading... And I bet that's what you're really talking about. > > Our system won't let that work at all.

Ok, now you're saying that a HUB is doing filtering... that's BOGUS. You've got a ROUTER doing filtering... TOTALLY different beast, although some All-in-one boxes have a built in Hub or Switch on a Router... some WAPs (Wireless Access Points) also have a built in RJ45 Switch nowadays, hiding behind a NAT Router; my WAP (A Dlink DL-614+) has a 4 port switch and the wireless gateway, hiding behind a NAT and MASQ router with a WAN port.

AH HAH! You >ARE< talking about a router; you're talking about a Broadband Wireless Router, >NOT A HUB<. It simply has a hub (or more likely a switch) built into the Green side of the router. It provides NAT, which means you're running an internal network with private IPs, while the router's Red interface has an public IP. You also probably have to configure it to allow certain traffic through, and it's probably advertised as a Firewall, as well, with rudimentary filtering capabilities on a stateless firewall. Yeah, my WAP at home can do that, too; I don't bother, except the NAT, since I use IPCop as my router, and pull that to a 100Mbit Switch (actually, two, in different parts of the house, using an uplink between them). My WAP hangs off one of the switches, but in the meantime, my IPCop does my Firewalling, DNS serving, acts as an HTTP proxy, NAT, etc. Of course I'm biased for the IPCop, but I prefer it to the WAP's firewall (though I may eventually flatten my network slightly by hanging everything off the WAP, with the firewall connected directly to the WAP's WAN port. That would mean someone would have to hack two firewalls to get to one of my machines, unless they came in over the wireless...) I don't fully trust the WAP's firewalling features (very limited control). > from linksys hub: > > - one wired PC running XP > - one wireless access laptop running RH 9 > > cost of linksys hub: $89 US. > > and yes, it works, it really does, given that both machines > are on the net constantly, as you can verify from my incessant > posts to RH-related mailing lists. :-) > > rday -- redhat-list mailing list unsubscribe mailto:[EMAIL PROTECTED] https://www.redhat.com/mailman/listinfo/redhat-list
