I solved the main issue, I did not realise that modules require compat_xtables module to be loaded. Once I used modprobe, it solved module dependency and module is loaded now: # lsmod Module Size Used by xt_ipv4options 780 0 compat_xtables 3894 1 xt_ipv4options So now only one small issue persits: once I edited mconfig file and I commented out all lines (by adding hash as the first char on the line) but "build_ipv4options=m" all modules were compiled and installed anyway.
