iptables, Netgear router

Carlee · 09-16-2004, 05:00 PM

How do I set iptables to work with a Netgear router?

Everything connected to the router slows, especially the Windows proxy server, when I use in RH-Lokkit-0-50-INPUT:
ACCEPT all -- 192.168.0.0/24 0.0.0.0/0

If I don't use that, the windows computers using the router can't get into the Linux (Redhat) server.

Thanks.

iptables sholuldn't be affected by the type of router hardware you're using. It sounds like your rules are too restrictive and are blocking normal traffic, untill you add the rule allowing everthing. If you could post your complete rule set and list the services and traffic you'd like to allow, it would probably be helpfull in determining the cause.

That's helpful.

Instead of trying to fix my old rules, would it be easier and reasonably secure to start over with Shorewall?

(I'm hoping I no longer need the restrictive rules blocking ChinaNet, which seems to have finally given up.)

Thanks.

Not really, but you can go ahead and install shorewall if you like. However if you post your rules we should likely be able to diagnose the problem (in theory

). If you don't care to learn about iptables and think that you'll need to modify your firewall in the future, then using a graphical interface like shorewall, firestarter, or guarddog might be worthwhile.
