Hello, I try to enable h323 helper for specific internal hosts. However system gives error "No such helper h323" Actually when I enable modules without disabling /proc/sys/net/netfilter/nf_conntrack_helper module seems work. Kernel is 3.5.3. What do you think the problem is? Regards, echo 0 > /proc/sys/net/netfilter/nf_conntrack_helper # iptables -A PREROUTING -t raw -p tcp -s 10.14.1.7 -j CT --helper h323 iptables: No chain/target/match by that name. # dmesg |grep -v lfp [502137.581136] xt_CT: No such helper "h323" # iptables -A PREROUTING -t raw -p tcp --dport 1720 -s 10.14.1.7 -j CT --helper h323 iptables: No chain/target/match by that name.
