I have been running Smallwall with great success on the long ago discontinued net4801-60 (256Mbyte SDRAM). I am wondering if anyone here has successfully used the net4801-50 or -48 which only has 128Mbyte SDRAM. Currently my memory status shows ~34% utilization so, in theory, it should be possible. I am speaking strictly of firewall application. No VPN, etc.
P.S. A litte more data
$ top -d1 last pid: 13557; load averages: 0.15, 0.11, 0.05 up 45+21:39:56 14:55:35 11 processes: 1 running, 9 sleeping, 1 zombie
In case anyone searches and finds this thread - I have been able to successfully run Smallwall on the net4801-50 with only 128MB RAM. No issues so far although my source feed is only 10Gbit. If you are trying to run serious Gbit networks this solution would not work for you.
