Hey all,
sorry if this is not purely Fedora related, but I was hoping I might get
some feedback anyhow from someone who knows more than I do.
I have this:
A NAT-configured router between my house and the internet.
A NAS behind the router.
A dyndns account, set up and pointing to the global address of the router.
I want to be able to reach the NAS from the internet. However, trying to
do so (including attempts to bind to specific ports on the NAS) simply
do not work, and I cannot tell why.
I have set up the router to port-forward the correct portcalls to the
NAS, but that does not solve anything.
So I am stuck, any tips?
system-config-firewall provides a fairly simple way to set up port
forwarding. But, it's a take-it or leave-it proposition. system-config-
firewall will either take over all of your iptables configuration, or you
have to roll your own on everything; however system-config-firewall does
allow you to specify an external file with fixed iptables rules that gets
incorporated into system-config-firewall-generated ones. So, you might be
able to migrate to system-config-firewall, even if you have some custom
rules installed.
Then, it's a matter of figuring out which ports need to be forwarded. Your
problem may not necessarily be a firewall rule config issue, but knowing
which ports you need to forward.
