Thank you GunnarD. It was an Apple 802.11n Airport which, out of the box, we couldn't connect to with the utility sw to config it. Apparently, it begins handing out IPs out of the box, or maybe it's just munged. We're good now.
I didn't check. Let me find out. But my understanding is that the 10.0.x.x address is some default the machine uses when it cannot get an address from the DHCP server.
ISC DHCP v3.0.3 running on a MacMini under OS X Tiger.
Ran fine for years.
Suddenly, most of my PCs can't get a valid Address.
When I go to the PC with a problem, this is the routine:
>ipconfig/all
IP: 10.0.1.130
SN: 255.255.255.0
GW: 10.0.1.1
>ipconfig/release
success
>ipconfig/renew
IP...
Okay, I have a 515 but I'm running 6.3, so your mileage may vary...some commands may be deprecated. Of course my REAL-WORLD-IP never changes.
fixup protocol http 80
...
access-list outside permit tcp any host [REAL-WORLD-IP] eq www
access-list outside permit tcp any host [REAL-WORLD-IP] eq 1600...
and by what domain name is the webserver known to the world? i.e., how are the people outside to access it? are you telling them the current IP you received from DHCP, or running a DNS server somewhere?
thanks for the background.
we spoke too soon. the link ran solid for 20-30 minutes, then began dropping out, just like before. we suspect that there was not much traffic when it was solid. we ran pings, connected to a few services on the other side of the link, etc, and it all seemed good...
jeff et al, i have to agree with lerdalt and jneiberger - we set the speed and auto on both routers and radios yesterday for the switchover this morning and the radio on one side was saying "ethernet speed and duplex mismatch" this morning. we changed all back to auto.
our tower guys were out...
thanks jeff. we've set the speed/duplex to 100/full on both the routers and both the radios. we will not test until tomorrow AM early. i'll post the result.
>So what else is there between the wireless bridges and the router on each end? A switch or larger fabric?
the radio towers (PoE) have cat5 that runs through lightning arrestors and then directly into the fastEthernet on the routers. we thought maybe we're beyond the distance limit for cat5...
>The big thing I question, not that it's an impact is why you aren't using a smaller mask on your wireless link.
good point. out of the box, the motos come config'd 169.254.1.1 and 169.254.1.2 255.255.0.0. we just changed over to 172.22.x.x and didn't bother with the subnet mask. but you're...

we have 2 cisco 3620 routers connected over two T1s. we use multilink to load balance traffic. we have fastEthernet in slots 0 and 1 on both routers. we shut down the T1s and the multilink and brought up the second fastEthernet with motorola wireless radio towers plugged in to them - motos run...
