Ip aliasing error?
Sorry my English. I have a firewall with a debian Woody installed
with a kernel 2.4.29. This it connected to internet trought HDSL
line with a Cisco router 1721 , bridge mode. Has configured 5
public ips by ip aliasing. The firewall works correctly although
before 4 or 5 days one of the ips they configured is not accessible
from internet. Since inside of the network responds correctly. If
ifdown and ifup the interface does not fix anything. If I configure
some host inside of the network with that Ip, is accessible from
Internet. Finally if I powerOff the router and powerOn again, all
correctly. Any suggestion?
