hi all,

i want to add a dyndns adress in firewall.

somethig like:
chain=forward action=accept src-address=192.168.1.3 dst-address=sample.dyndns.org <--- thats my problem. ip adress changes, i need to add the dyndns name...

is that possible ?

Sure it's possable

sorry, maybe i described wrong.

for my own dyndns i use this script already, works well.


but now, i need a firewall rule to accept incoming connections from dyndns.

i need to accept incoming connections from:

sample.dyndns.com to port 4130 on my router

but i only can ad ip adresses in firewall (src adsress), not the dyndns name

why u wanna add DDNS by name address not IP? http://baremetal.com/cgi-bin/dnsip

Why not run a script periodically that resolves the IP from a hostname and alters the rule if there is a change? This should be fairly easy to do. You can (I am certain) find someone who will program this for a fee. (I have done similar things in the past).

A scripted solution is even available on the wiki:

od3m, if you search the forum for your question you'll find it's something that has come up quite a bit in the past, with the arguments for and against this feature.

thx,
i didnt find this solution in the wiki.
thx for that link.
it does exactly what i want.

i know the security reasons.
but i need this only for one dyndns name i need to resolv. and the source i trust.

so again,
thank you

i thought it would run...
but nothing happens.

resolve hostname doesnt bring any ip´s for hostnames.
i think there´s the mistake
it should or ?

Kind of hard to give an answer without details on your firewall rules and the script as you edited it.

works now !
thx again
