I'm using ArchLinux and I have an IP tables rule that I know works (from my other server), and it's in /etc/iptables/iptables.rules, it's the only rule set in that directory. I run, /etc/rc.d/iptables save, then /etc/rc.d/iptables/restart, but when I do "iptables --list", I get ACCEPTs on INPUT,FORWARD & OUTPUT.

How do I redirect all the UDP traffic on port 27016 of my current dedicated server to a new IP port 27015 using IP tables?

View 1 Replies View RelatedQuestion (and Google results aren't making this clear): Ubuntu has both iptables & ip6tables installed. 1. If I set a rule in iptables, does that rule also apply to ipv6, or just ipv4?
2. If "no" to above, then it would be prudent to *also* set ip6tables rules as well if I want to maintain an active firewall, correct?
3. Does ip6tables rules have the same syntax and behavior (more or less) to iptables rules - i.e. can I just copy my iptables rules & change "iptables" to "ip6tables"?
4. Any gotchas or issues that I should be aware of?

View 3 Replies View RelatedI'm running Ubuntu 9.10 (Karmic Koala) on a laptop and would like NumLock to automatically toggle depending on whether my USB keyboard is plugged in (numlock on) or unplugged (numlock off).
To accomplish this, I first installed the "numlockx" package. numlockx on and numlockx off works fine.
To hook into the device system, I thought I'd use udev. I have read "Writing udev rules", but I'm having trouble getting the udev rule to work.

I can't work out how to save the iptables. I searched the whole system for files/folders containing the name "iptables" and got 3 results:
/user/local/lib/iptables
/sbin/iptables
/lib/iptables
I've tried iptables save, iptables-save and iptables save active.
"iptables save" and "iptables save active" give me an invalid argument error. "iptables-save" isn't a valid command. "iptables --help" gives me a list of valid switches, none of which have to do with saving.
how I can save the iptables?

Config a CentOS iptables.I issued some iptables rules.the rules were effective at once.Then, I came with a "iptables-save", but the "/etc/sysconfig/iptables" file hasn't been updated, it still loads the defaults rules with CentOS after reboot.
View 4 Replies View RelatedI have 2 routers both with 5 network cards (both different subnets). On both machines I have the following configuration: Eth0 is the internet conection, Eth1 is the conection to the other router and the other network cards are for the subnets.My current Ip tables script allows all the subnets of one router to see each other but not the subnets of the other router.
In the new situation I want not all but specific subnets to see each other (no problem here)The issue is that some of theese subnets are subnets of the other router. For example the subnet of eth2 router1 should be able to connect to eth 3 on router2. This is were eth1 comes in play. My plan was to configure iptables so that in above example eht2 would be forwarded to eth1, which will forward to eth1 on router2.Then the iptables configuration on router2 will forward it to the network card of the correct subnet.
eth2 (router1) -> eth1 (router1)
eth1 (router1) -> eth1 (router2)
eth1 (router2 -> eth3 (router2)
