I am trying to setup iptables on udoo quad but I hit a brick wall and cannot find a fix anywhere: root@udoo:/tmp# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination root@udoo:/tmp# iptables -S -P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT root@udoo:/tmp# iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT iptables: No chain/target/match by that name. root@udoo:/tmp# cd /tmp root@udoo:/tmp# cp /proc/config.gz . root@udoo:/tmp# gunzip config.gz root@udoo:/tmp# grep CONNTRACK config # CONFIG_NF_CONNTRACK is not set How do I add the module to the kernel? ... or do I need to compile new kernel? Any suggestions would be appreciated. Thx
Hi I have the same problem for use my UDOO board in hotspot and share internet from eth0 to wlan0 and use br0 for dhcp server and bridge br0->wlan0... I followed this instructions https://gist.github.com/2xyo/8452047 but it's worked one time and since reboot impossible to route packets from iptables.... The ipt_MASQUERADE and conntrack... modules are up but the iptables rules does not work anymore....
I have recompiled kernel as described here: https://it.awroblew.biz/quad-core-udoo-debian-compiling-kernel-4-0-8/
