Hi I have problems with NAT - i cant run masqueradnig at all ;-( when i try ipnatctl -I -s 10.0.0.0/24 -b source -m masquerade or ipnatctl -I -o eth0 -b source -m masquerade i always have error setsockopt problem: Invalid argument all modules is loaded... (i use example script from QUICKSTART) ipchains&2.2 kernel work fine... I really want to use netfilter code & all is work fine - exclude masquerading ;-(
