I can access web GUI on my m0n0wall machine only few minutes after
m0n0wall boots for the first time or until I save any changes I have
made. After that any connection to m0n0wall web server times out
although I can ping machine running m0n0wall and it replies in under 1ms.

I’m running m0n0wall on Pentium 200 MMX machine with 64MB SD-RAM and wd
4GB hard drive. Hard drive has no bad sectors. I have also tested memory
with Memtest86 and it returned no errors.

Cheers
Toma
