I have a WB Quad Rev. C1, got Ubuntu 15.10 on it and got rid of the X11 and any GUI related items, in an attempt to transform it into a home file server. So far, so good - things work fine until now, but I realized that this kernel doesn't have support for iptables. Any chance of compiling a kernel that would have support for iptables? Can anyone help me on this one? Thank you very much!
