Hardware

I have currently alix2d13 hardware with monowall 1.33.
This system seam drop tcp packets with option field 76 , 77 , 78 needed from Riverbed WAN optimizers to discovery each other on the way with probes.
How can prevent dropping this packes in monowall or how can I install older Version 1.2x on this hardware where I disable firewall / filter.

It seem older hardware with version 1.21 will work because ipfilter is disabled.
I only need traffic shaper without ip filter.

You can find old versions here:

but only 1.3x above for this hardware

where can I find 1.2x

I believe the WRAP images are what you are looking for. But I could be wrong.

m0n0wall 1.21 will most likely not work on ALIX.

If you just want to disable ipfilter, then the command "ipf -D" (issued via /exec.php) should do the trick. To make it permanent, add it in a <shellcmd> tag to the <system> section of config.xml.
