Did you build your own kernel or are you inside a VM like OpenVZ? Because it seems odd that OVH has left this out from the kernel. Anyway, typing "modprobe iptable_filter" will add this manually, and with "lsmod | grep ip" you should see it listed. If not, then your kernel does not support this and you need to use a different one (or compile with CONFIG_NETFILTER=y).

I have the same problem and when I try that, This message shows:

iptables v1.3.8: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded

Is it TCP or UDP (I don't know anything about Ventrillo)? Anyway, I'm not sure how your iptables is setup, but something like this should work:

iptables -A INPUT -p tcp -m tcp --dport 3784 -j ACCEPT

Simply replace tcp with udp if that's the protocol used. But keep in mind that generally a lot of voice or chat apps also need additional ports. So be sure to check what other ports it needs (ie., is there a dynamic range of 10200-10300 ports used?)

(come to think of it, you may need to add is as -A FORWARD... Give it a try.. )

Hello there,
I've had my RPS I for a few weeks and haven't had a single problem. I'm currently struggling to open up a port for a small ventrilo server. It's just so me and the fellow admin team on my community can converse more easily than via PMs and instant messaging.

I cannot for the life of me seem to figure out how to open up port 3784, I have quite literally sat here since half 6 plugging in whatever I could find on google into iptables which predictably hasn't worked

OS: OVH Gentoo

Thanks for any replies.
