The Wireless ISP made a change to the network, and I can only get into the wireless router via a web interface, when it is not connected to the wireless ISP. [7.0-CURRENT] <---> [10/100 SWITCH] <---> [wireless router] <-~~~-> Wireless ISP [6.x-STABLE] <--------------^ Note: the 6.x system wasn't powered on at the time this problem occured. arp -an was only showing the MAC address of the rl0 interface. tcpdump on rl0 was showing the wireless router arping for the MAC address of rl0, but no response by rl0. pinging the wireless router, tcpdump was showing rl0 arping for the MAC address of the wireless router, but no response by wireless router. Currently the problem hasn't reoccured. Scot -- DISCLAIMER: No electrons were mamed while sending this message. Only slightly bruised.
