Subject: ping from 'wrong' ip-address
Date: Wed, 26 Feb 2003 15:13:51 +0100 [thread overview]
Message-ID: <20030226141351.GA23528@first.knowledge.no> (raw)
A 1/8 subnet (32-64). Pinging had suddenly changed from using the correct
ip-address for the external interface to use the ip-address for the first
alias for this interface (eth1:0). I can't ping outside anymore.
The ip-address for eth1:0 was previously a machine on the network, that
now has been moved to a reserved ip-address on the LAN.
Could this be a ARP-cache-problem?

Anyone familiar with this problem?
