Xen: iptables issue

vm3:/# iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j DNAT --to-destination 85.12.6.173:8180
WARNING: Could not open 'kernel/net/netfilter/x_tables.ko': No such file or directory
FATAL: Could not open 'kernel/net/ipv4/netfilter/ip_tables.ko': No such file or directory
iptables v1.4.2: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Solution:

vm3:/# depmod
vm3:/# iptables -t nat -A PREROUTING -p tcp -m tcp --dport 80 -j DNAT --to-destination 85.12.6.173:8180

All ok 🙂
