Im having a problem with a m0n0 (1.3b2) that has problems handing out new
dhcp leases after about 2 or 3 days running, the system is still responsive,
meaning that I can login to the web interface and reboot the machine (WRAP
128MB RAM 233Mhz), but the system doesn't hand out any new ip addresses to
clients. I originally thought the issue was with the logs filling up, still
don't know if this is the case, I stopped logging the default rules and
started pushing the logs out to a syslog server instead but the server is
still doing the same thing.

 

One thing that I've noticed is that in the Diagnostics -> DHCP Leases page
I'm seeing the same machine multiple multiple times at slightly different
times.

 

Snippet

 

IP address  MAC address      Hostname        Start
End

Is there any workaround to this problem?
